AUO Showcases Industry Strength at PV Taiwan 2010

HSINCHU, Taiwan, October 25, 2010 - AU Optronics Corp. ("AUO" or the "Company") (TAIEX: 2409; NYSE: AUO)
announced today that the Company will showcase the latest PV products at PV
Taiwan 2010. SunForte PM318B00, a high-efficiency mono-crystalline solar
module, will make its debut in Taiwan. Besides, in order to highlight its
solar competitiveness, AUO will also demonstrate the multi-crystalline EcoDuo
PM240P00 and EcoDuo PM250P00 solar modules.

For the urban areas with smaller rooftops, AUO will launch the SunForte
PM318B00 with a conversion rate as high as 19.5%, which is 5.5% higher than
the rate of the conventional module in the industry. The product will
maximize the solar power output for solar system users.

In addition, EcoDuo PM240P00, the same-sized upgraded model of the
multi-crystalline solar module PM220, has raised its output power to 240W,
which is 10% higher than its predecessor. EcoDuo PM250P00, with an output
power of 250W, will also be showcased at the exhibition.

Since 2008, AUO has dedicated itself to collaboration with solar
partners. As a result, the joint venture solar cell fabrication facility in
Malaysia, AUO SunPower Sdn. Bhd., has successfully manufactured the initial
production of solar cells, yielding a minimum conversion efficiency of 22.2%.
It demonstrates AUO SunPower's high-quality product technology and strong
manufacturing capability.

Other than the solar system project in Europe, AUO Solar dedicates to
Taiwanese solar system development and low-carbon engineering. AUO has just
completed the construction of 30KW solar system on the rooftop of AUO
Taichung Fab I. Also, a rooftop solar system of 134KW at the AUO Dormitory in
Houli started to operate recently. The other construction of 10MW solar
system project in AUO's Taichung Fab II is currently in process, which will
showcase AUO's technology and integration competence in the solar business.
The efforts also realize the goals of using renewable energy and achieving
low-carbon fabs.
