EXHIBIT INDEX 99.1 Press Release Dated August 18, 2003, with respect to declaration of a $0.15 per share quarterly cash dividend to be paid October 17, 2003. 4

                                                                    Exhibit 99.1

          Gentex Corporation Declares Initial Quarterly Cash Dividend

    ZEELAND, Mich., Aug. 18 /PRNewswire-FirstCall/ -- Gentex Corporation, the
Zeeland, Michigan-based manufacturer of automatic-dimming rearview mirrors and
commercial fire protection products, today announced that its Board of
Directors approved a change in the Company's cash dividend policy and has
declared an initial quarterly cash dividend.  The quarterly dividend of
$0.15 per share will be payable October 17, 2003, to shareholders of record of
the common stock at the close of business on October 3, 2003.

    "It's unusual for a growth company to pay a cash dividend," said Garth
Deur, Gentex executive vice president.  "However, based on The Jobs and Growth
Tax Relief Reconciliation Act of 2003, which has significantly reduced the
federal income tax rate for shareholders who receive corporate cash dividends,
the declaration of a dividend is now a more tax-efficient means of returning
value to shareholders."

    Deur said that declaring a quarterly cash dividend demonstrates the Board
of Director's confidence in the Company's long-term growth opportunities,
strong net income and cash flow from operations, and solid financial
condition.   He said that he believes paying a cash dividend will make Gentex
stock even more attractive to a broader range of investors.

    "We are pleased to be able to return a portion of our net earnings to our
shareholders, while maintaining our significant investment in research and
development," said Deur.  "In the short term, the uncertainties in the economy
and in global automotive light vehicle production schedules make it difficult
to forecast with any degree of certainty.  A very early look at automotive
mirror unit shipments in calendar 2004 indicates potential growth of
approximately 10-15 percent over calendar 2003."

    "Over the long term, we see significant potential for growth in our core
auto-dimming mirror business, including the addition of electronic features to
both interior and exterior mirrors.  We remain committed to attracting
investors who share our enthusiasm and long-term view of the Company's growth
opportunities," said Deur.

    Certain matters discussed in this news release, including growth rate
trends, future performance, and the impact of electronic features in mirrors,
are forward-looking statements which involve certain risks and uncertainties,
and are subject to change based on various market, industry and other
important factors.  The Company cautions investors that numerous factors (some
of which are outlined in the Company's Form 10-K filed with the Securities and
Exchange Commission and other interim reports) and future events may affect
the Company's actual results, and may cause those results to differ materially
from those expressed in this news release.  Furthermore, Gentex undertakes no
obligation to update, amend, or clarify forward-looking statements whether as
a result of new information, future events, or otherwise.
