AUO Showcases the World's Highest Efficiency PV Module at SNEC 2011

HSINCHU, Taiwan, February 21, 2011 - AU Optronics Corp. ("AUO" or the "Company") (TAIEX: 2409; NYSE: AUO) will
attend 2011 SNEC 5th International Photovoltaic Power Generation Exhibition &
Conference and showcase the world's highest efficiency PV module SunForte
PM318B00 with a conversion rate up to 19.5% and eco-friendly PV modules. AUO
will deliver low-carbon, advanced and high-quality total green solutions to
clients through its world's highest efficiency vertical solar value chain.

AUO is a global leading low-carbon TFT-LCD corporation and has been
developing proactively its solar business since 2008. The company, by
acquiring M.Setek, and joint venturing with SunPower, has created the world's
highest efficiency vertical solar value chain, including polysilicon raw
material, solar cell, PV module and system projects. AUO has also established
its first high-efficiency PV plant in Tianjin, which will be the first PV
plant in China acknowledged by U.S. Green Building Council's LEED (Leadership
in Energy and Environmental Design) certification. The plant is designed to
be a green facility, with construction and equipment installation expected to
complete this year. Its total capacity will reach 1GW.

In addition to establishing green PV plants, AUO has engaged itself in
promoting carbon footprint verification for products. AUO's EcoDuo PM220P00
is the world's first PV module to have passed PAS2050 carbon footprint
verification by SGS, signifying a critical milestone for the PV industry. AUO
will also benchmark all its future PV modules against this standard and
devote itself to energy-saving designs, raw material reduction or
replacement, and develop innovative R&D technologies to effectively lower
total CO2 emissions and reduce carbon footprints in products.

In 2011 SNEC 5th International, AUO will display the high efficiency
mono-crystalline SunForte PM318B00 that targets densely populated urban areas
with smaller rooftops. The SunForte PM318B00 has a conversion rate as high as
19.5%, the world's highest for PV modules, and the output is approximately
40% higher than that of the conventional module in the industry with
conversion rate of 14%. The product will maximize the solar power output for
solar system users. Moreover, AUO will also demonstrate its PM240P00 PV
module that could withstand salt corrosion and moisture in coastal or humid
areas, making the power systems more efficient. All AUO high-efficiency PV
modules are tested for power performance and durability in UL certificated
laboratories, meeting CGC, TUV, UL, IEC standards to assure customers of
excellent long-term first class power generation warranty. In the future, AUO
will continue to take advantage of its world's highest efficiency vertical
solar value chain to design low-carbon and high efficiency PV products, and
offer high quality total green solutions to customers with its innovative R&D
strengths and mature supply chain management systems.
