AUO Demonstrates Its R&D Strength to Showcase a Full Lineup of PV Products at Solar Power International 2010

HSINCHU, Taiwan, October 11, 2010 - AU Optronics Corp. ("AUO" or the "Company") (TAIEX: 2409; NYSE: AUO)
announced today that the Company will participate in Solar Power
International 2010 to showcase its full lineup of PV products. SunForte
PM318B00, a high-efficiency mono-crystalline solar module, will make its
debut in the show. The product employs high-efficiency mono-crystalline solar
cells and has a conversion rate as high as 19.5%.

Solar Power International 2010 will be held in Los Angeles, U.S.A., from
Oct. 12-14. The show is organized by the Solar Electric Power Association
(SEPA) and the Solar Energy Industries Association (SEIA). It is one of the
most noted professional PV trade shows in the world.

In addition to the solar module with the highest conversion rate, AUO
will be displaying the AC Module for the U.S. residential market. AUO leads
the industry by applying an anti-reflection coating to the AC Module, which
increases the conversion rate by 4%, maximizing the system's output power.
The system is therefore free from output power degradation in case of
shadowing, easy to install and maintain, and highly expandable.

The mainstream multi-crystalline solar module EcoDuo PM220P01 is also
among the exhibits. The module is on the CEC (California Energy Commission)
listing under the solar electricity systems category. Furthermore, EcoDuo
PM240P00, the upgraded model of the multi-crystalline solar module PM220, has
an output power that is 10% higher than its predecessor, from 220W to 240W.
Worthy of note, the PM220P00 of the same series is the world's first PV
module to have obtained carbon footprint verification.

AU Optronics Corp. comments that as one of the few companies worldwide
possessing cutting-edge technology for high quality TFT-LCD panels, the
Company's experiences and technologies in TFT-LCD production and yield rate
control have been passed on to the development of solar modules. The
expertise along the value chain from materials, modules to power system
development, is thus better secured. The participation to Solar Power
International 2010 will demonstrate AUO's strengths in R&D and its fruits.
The occasion will also present enormous opportunities for the Company to
further develop the North American PV market.

AUO is currently the only "total solutions" provider that tops the
industry in various technological domains of the vertical solar value chain,
including the solar wafers that produce the highest efficiency solar cells,
the solar cells with the highest conversion rates, and the establishment of
solar module plants worldwide. Following the mass production of solar modules
in the Taiwan (Taichung) and Czech sites, AUO will also set up its second
solar module plant in Tianjin, China for an expected capacity of 1GW. AUO
will continue to accelerate its solar development to complete the industry
value chain, providing customers with even more satisfactory products and
services from upstream to downstream.
