A Series of Mobile Device Technologies to be Showcased at SID Display Week
                                    2008

    HSINCHU, Taiwan, May 19 /Xinhua-PRNewswire-FirstCall/ -- AU Optronics
Corp. ("AUO" or the "Company") (TAIEX: 2409; NYSE: AUO) is unveiling today
the world's first* Curved Display Technology on glass substrate. This
technology will be exhibited at SID (Society for Information Display)
Display Week 2008, from May 20 through 22 in Los Angeles, California. In
addition, a series of mobile device technologies will be showcased for the
first time at the exhibition.

    Curved Display Technology

    The world's first* Curved Display is developed and produced by AUO with
TFT-LCD process on glass substrate. The curved radius is 100mm, and
therefore requires a special thinning technology. The specially designed
curved backlight unit maintains uniformity in brightness and contrast on
the curved surface. Unlike the existing e-paper on a flexible substrate,
AUO's new curved display technology can bring TFT-LCD technology into play
in terms of both color performance and image quality. Therefore, it could
be applied to some curved display applications in the future, such as
watches and dashboards.

    World's Thinnest* Ultra Thin 0.63mm for Mobile Phone Applications

    AUO will also demonstrate a series of mobile device technologies, in
which the world's thinnest* Ultra Thin 1.9-inch TFT-LCD is expected to grab
the spotlight. This ultra thin TFT-LCD, with a thickness of merely 0.63mm,
broke AUO's own record of 0.69mm released at FPD International 2007 in
Japan. This 8-inch TFT-LCD uses special glass thinning technologies,
shrinking the thickness of related components, to achieve 0.63mm in
thickness, 2.1 grams in weight and 400nits in brightness. The end result is
a multitude of desired features -- light, slim, elegant and sunlight
readable, to meet current mobile lifestyles.

    In-cell Multi-Touch Technology

    AUO is also showcasing its in-cell multi-touch technology through
4.3-inch and the latest 8-inch TFT-LCDs at SID's Display Week 2008. Unlike
the current touch panels in the market, AUO's in-cell multi-touch TFT-LCD
integrates touch function features into the TFT manufacturing process
without adding an additional glass. In addition, it has superior anti-glare
properties to retain proper image color saturation and readability in
direct sunlight. AUO's in-cell multi-touch technology has been successfully
applied to 4.3-inch products and will be in mass-production in Q2 2008. It
is regarded as one of only a few touch-panel technologies worldwide that
integrate touch features directly into the LCD cell manufacturing process.

    Grease Free and Touch Mura Free Technology

    Another AUO innovation is its Grease Free and Touch Mura Free
technology that accomplishes better performance for the booming touch panel
display market. This technology coats the AF (Anti-Fouling) layer as part
of the surface treatment of the polarizer, therefore attaining a
fingerprint free surface. In addition, its grease-resistance features help
to easily wipe off smudges and grease from the display. By adopting AUO's
self developed AMVA- mobile technology, touch mura free function features
make information easy to read without touch mura. The three features of
fingerprint free, grease free and touch mura free are ideal technologies
for touch panels. This technology will be demonstrated on a 2.4"
AMVA-mobile panel.

    "In recent years the small- and medium-sized display market has become
increasingly competitive, fostering the depth and width of its technology.
In addition, the 3 major trends -- human interface, system integration and
thin- and-light eco products, are still dominating the market," said Dr. CT
Liu, AUO Vice President & GM of Consumer Product Display Operations. "Being
an industry leader, AUO will be leveraging the advantages of its TFT-LCD
manufacturing process integration with the aim to produce value-added
TFT-LCDs and deliver customer- and consumer-oriented products and
technologies."
