SEMI-ANNUAL REPORT

TCW CONVERTIBLE SECURITIES FUND, INC.
[TCW LOGO]

DEAR SHAREHOLDER:

The equity markets started off in 2004 with positive returns in January and
February; however, they gave up most of their gains by the end of April due to
concerns over lack of job creation and terrorism. The change in non-farm
payrolls increased by an average of over 200,000 per month during the months of
April, May and June, signaling the economic recovery was gathering steam and was
no longer a "jobless recovery." Markets took this information as a sign the Fed
could no longer sustain its accommodative stance toward interest rates, fearing
a rise in inflation. As a result, markets began to factor this information into
stock and bond prices only to be surprised by warnings about business outlooks
from the likes of Wal-Mart and select technology stocks, creating a volatile
second quarter.

PERFORMANCE OF THE FUND'S SHARES:

For the six months ended June 20, 2004, the net asset value of the TCW
Convertible Securities Fund, Inc. (the "Fund") increased by 3.4%. For the same
period, the CS First Boston Convertible Securities Index generated a total
return of 2.9% while the S&P 500 Index delivered a total return of 3.4%. While
the net asset value of the Fund increased during this six month period, the
market price of the Fund continued to trade at a discount to net asset value and
returned -1% with dividends reinvested. The discount, which averaged 13.2% with
a high of 17.3% during the first half of 2004, increased approximately 4%. The
increase in the discount was in-line with the performance of other closed-end
convertible funds during this period of rising interest rates.

The Fund paid a total dividend of eight cents per share in the first half of
2004. The Fund's dividend distribution is highly dependent on the level of short
and intermediate term interest rates. As rates rise or fall, Fund income is
likely to move in the same direction.

PORTFOLIO STRUCTURE AND STRATEGY:

The Fund buys securities of companies that exhibit strong and improving business
fundamentals. The Fund does not purchase securities that may be in default or
where the dividends are in arrears. We continued to structure the Fund so that
it has modestly higher exposure than its convertible benchmarks to a rising
equity market. An expanding economy with low inflation, accompanied by a likely
continued recovery in Europe and Japan is expected to result in a positive
market return for the year. Offsetting these positives have been persistently
high and rising energy prices, the Presidential race and fears of terrorism.

In response to the current low interest rate environment, the fund has modified
its portfolio holdings in order to enhance income. The fund currently has an
average rating of BB+, with over 53% of its securities being investment grade,
down slightly from 2003. Secondly, the Fund's holdings in convertible preferreds
has risen to approximately 48%. This allows the Fund to pick up income and
maintain exposure to a rising equity market, though the net sensitivity to
equity prices has been reduced slightly.

We believe that the Fund is structured to benefit in an environment of moderate
economic growth with a modestly improving stock market. As of June 30, 2004, the
annualized current yield of the Fund is 3.31%. The yield to maturity on its
convertible bonds is over 4.5%. We believe that the Fund has good exposure to
improving equity markets given its sector allocation and the structural
characteristics of its convertible securities. The Fund is broadly diversified
with 79 holdings in over 26 industries.

SHARE REPURCHASE PLAN

The Fund completed the Share Repurchase Plan (the "Plan") in the first quarter
of 2004 by repurchasing 899,300 shares at an average price of $5.22 per share
(average discount of 10.56% from NAV). The Fund

                                        1


started the Plan in 2000 by repurchasing 624,700 shares, and in 2003, it
repurchased an additional 1,476,000 shares. In total, the Fund repurchased
3,000,000 shares as authorized by the Fund's Board of Directors.

DIVIDEND REINVESTMENT PLAN

Shareholders who wish to add to their investment may do so through the Dividend
Reinvestment Plan (the "Plan"). Under the Plan, your dividend is used to
purchase shares on the open market whenever shares, including the related sales
commission, are selling below the Fund's Net Asset Value per share. If the
market price, including commission, is above the Net Asset Value, you will
receive shares at a price equal to the higher of the Net Asset Value per share
on the payment date or 95% of the closing market price on the payment date.

To enroll in the Plan, if your shares are registered in your name, write to The
Bank of New York, Church Street Station, P.O. Box #11002, New York, New York
10277-0770, or call toll free at (800) 524-4458. If your shares are held by a
brokerage firm, please call your broker. If you need assistance, please call our
investor relations department at (877) 829-4768 or visit our website at
www.tcw.com. As always, we would be pleased to accommodate your investment
needs.

DISCLOSURE OF PORTFOLIO INFORMATION

As stated previously, it is the policy of the Fund to provide certain unaudited
information regarding its portfolio composition as of month-end (the "Portfolio
Holdings") to shareholders and others upon request to the Fund, beginning on the
15th calendar day after the end of the month (or, if not a business day, the
next business day).

Shareholders and others who wish to obtain Portfolio Holdings for a particular
month may make a request by contacting the Fund between 7:00 a.m. and 5:00 p.m.
Pacific time, Monday through Friday, toll free at (877) 829-4768 beginning on
the 15th day following the end of that month (or, if not a business day, the
next business day).

Persons making requests will be asked to provide their name and a mailing
address, e-mail address or fax number. The Fund reserves the right to refuse to
fulfill a request if it believes that providing Portfolio Holdings would be
contrary to its best interests.

In addition to the policy stated above, the Fund may disclose Portfolio Holdings
at other times to analysts or rating agencies. The disclosure of Portfolio
Holdings in this context is conditioned on the recipient agreeing to treat such
Portfolio Holdings as confidential (provided that analysts and rating agencies
may publish portfolio positions upon the consent of the Fund), and to not allow
the Portfolio Holdings to be used by it or its employees in connection with the
purchase or sale of Fund shares. In addition, Portfolio Holdings are provided or
otherwise available to third-party service providers of the Fund, including the
Fund's custodian, pricing services, and administrators, as necessary for the
provision of services to the Fund.

Sincerely,

TCW CONVERTIBLE SECURITIES FUND, INC.
NOTES TO FINANCIAL STATEMENTS (UNAUDITED)
[TCW LOGO]

NOTE 1--SIGNIFICANT ACCOUNTING POLICIES:

TCW Convertible Securities Fund, Inc. (the "Fund") was incorporated in Maryland
on January 13, 1987 as a diversified, closed-end investment management company
and is registered under the Investment Company Act of 1940, as amended. The Fund
commenced operations on March 5, 1987. The Fund's investment objective is to
seek a total investment return, comprised of current income and capital
appreciation through investment principally in convertible securities. In
accordance with the requirements of Rule 35d-1 under the 1940 Act, the Fund will
invest, under normal market conditions, at least 80% of its net assets, plus any
borrowings for investment purposes in convertible securities. The 80% investment
policy described above is non-fundamental and may be changed by the Board of
Directors to become effective upon at least 60 days' notice to shareholders.

The preparation of the accompanying financial statements requires management to
make estimates and assumptions that affect the reported amounts of assets and
liabilities at the date of the financial statements as well as the reported
amounts of income and expenses during the reporting period. Actual results could
differ from those estimates.

The following is a summary of the significant accounting policies consistently
followed by the Fund in the preparation of its financial statements. The
policies are in conformity with accounting principles generally accepted in the
United States of America.

SECURITY VALUATION: Securities traded on national exchanges are valued at the
last reported sales price or the mean of the current bid and asked prices if
there are no sales in the trading period. Other securities which are traded on
the over-the-counter market are valued at the mean of the current bid and asked
prices. Short-term debt securities with maturities of 60 days or less at the
time of purchase are valued at amortized cost. Other short-term debt securities
are valued on a mark-to-market basis until such time as they reach a remaining
maturity of 60 days, where upon they will be valued at amortized value using
their value on the 61st day prior to maturity.

SECURITY TRANSACTIONS AND RELATED INVESTMENT INCOME: Security transactions are
recorded on the trade date. Dividend income is recorded on the ex-dividend date,
while interest income is recorded on the accrual basis. Discounts, including
original issue discounts, and premiums on securities purchased are recognized as
interest income and expense, respectively, using a constant yield-to-maturity
method. Realized gains and losses on investments are recorded on the basis of
identified cost.

DISTRIBUTIONS: Distributions to shareholders are recorded on ex-dividend date.
The Fund intends to distribute its investment company taxable income quarterly
and to distribute any net realized capital gains at least annually, to the
extent required for U.S. federal income tax purposes. The Board of Directors
also may, in its discretion, choose to pay distributions in excess of net
investment income and net realized capital gains, though it is not required to
do so.

Income and capital gain distributions are determined in accordance with income
tax regulations which may differ from accounting principles generally accepted
in the United States of America. These differences may be primarily due to
differing treatments for losses deferred due to wash sales and spillover
distributions. Permanent book and tax basis differences relating to shareholder
distributions will result in reclassifications

                                       11


to paid-in-capital and may affect net investment income per share.

REPURCHASE AGREEMENTS: The Fund may invest in repurchase agreements secured by
U.S. Government Securities. A repurchase agreement arises when the Fund
purchases a security and simultaneously agrees to resell it to the seller at an
agreed upon future date. The Fund requires the seller to maintain the value of
the securities, marked to market daily, at not less than the repurchase price.
If the seller defaults on its repurchase obligation, the Fund could suffer
delays, collection expenses and losses to the extent that the proceeds from the
sale of the collateral are less than the repurchase price. The Fund did not
enter into any repurchase agreements for the six months ended June 30, 2004.

NOTE 2--FEDERAL INCOME TAXES:

It is the policy of the Fund to comply with the requirements of the Internal
Revenue Code applicable to regulated investment companies and distribute all of
its net taxable income, including any net realized gains on investments, to its
shareholders. Therefore, no federal income tax provision is required.

At June 30, 2004, the Fund had the following net realized loss carryforwards:

NOTE 3--INVESTMENT ADVISORY AND SERVICE FEES:

TCW Investment Management Company (the "Advisor") is the investment advisor of
the Fund. As compensation for the services rendered, facilities provided, and
expenses borne, the Advisor is paid a monthly fee by the Fund computed at the
annual rate of 0.75% of the first $100 million of the Fund's average net assets
and 0.50% of the Fund's average net assets in excess of $100 million.

NOTE 4--PURCHASES AND SALES OF SECURITIES:

For the six months ended June 30, 2004, purchases and sales or maturities of
investment securities (excluding short-term investments) aggregated $150,710,655
and $153,612,883, respectively. There were no purchases or sales of U.S.
Government securities for the six months ended June 30, 2004.

NOTE 5--SECURITY LENDING:

During the six months ended June 30, 2004, the Fund lent securities to brokers.
The brokers provided collateral, which must be maintained at not less than 100%
of the value of the loaned securities, to secure the obligation. At June 30,
2004, the cash collateral received from the borrowing brokers was invested in
short-term investments valued at $46,971,831 which is 102.5% of the value of the
loaned securities.

NOTE 6--DIRECTORS' FEES:

Directors who are not affiliated with the Advisor received, as a group,
aggregate fees and expenses of $43,036 from the Fund for the six months ended
June 30, 2004. Certain officers and/or directors of the Fund are also officers
and/or directors of the Advisor.

                                       12


NOTE 7--RESTRICTED SECURITIES:

The Funds are permitted to invest in securities that are subject to legal or
contractual restrictions on resale. These securities generally may be resold in
transactions exempt from registration or to the public if the securities are
registered. Disposal of these securities may involve time consuming negotiations
and expense, and prompt sale at an acceptable price may be difficult. There are
no restricted securities (excluding 144A issues) at June 30, 2004.

NOTE 8--SHARE REPURCHASE PLAN:

In 2000, the Fund's Board of Directors approved the Shares Repurchase Plan (the
"Plan") authorizing the Fund to repurchase up to 2 million shares of its common
stock. In 2003, the Board authorized an additional 1 million shares to be
repurchased pursuant to the Plan. The purpose of the Plan was to enhance the
shareholders' value during the time when the stock price traded at a discount to
the Fund's net asset value per share. The Fund completed the Plan in the first
quarter of 2004 repurchasing all 3 million shares authorized. The following is
the summary of the Plan:



                                 2000             2003             2004            TOTAL
