AUO to Showcase Its Competitive Edge in the Solar Industry Value Chain at Japan's PV EXPO

HSINCHU, Taiwan, March 1, 2010 - AU Optronics Corp. ("AUO" or the "Company") (TAIEX: 2409; NYSE: AUO) will
exhibit at PV EXPO 2010 in Tokyo Big Sight, Japan from March 3-5 to showcase
its competitive edge in the solar industry value chain. High quality
polysilicon, ingots and wafers produced by M.Setek and high-efficiency
mono-crystalline and multi-crystalline PV modules from AUO will be on
display.

The PV EXPO in Japan is one of the most noted professional PV trade shows
in the world, as well as the most important business platform of the Asian PV
industry. There are 570 exhibitors worldwide participating this year,
displaying a full range of technologies for materials, equipment, solar cells
and modules, photovoltaic systems and integration schemes. It is a
must-attend event for vendors who wish to break into the Japanese and Asian
PV markets.

AUO will be exhibiting the high-efficient module Mono 245W, which is
capable of generating more power on space-limited rooftops with an impressive
conversion rate of 14.7%. It weighs merely 20kg, around 15% lighter than
modules of the same size in the market, and is also easy to install.
Customers have their options of choosing black or white colored modules to
match the designs of their buildings.

In its energy business, AUO has both the quality key materials from
M.Setek in the upstream and photovoltaic system projects in the downstream to
provide the most competitive total solution. Therefore, the company will
exhibit quality material with high conversion rates at the PV EXPO to
demonstrate its strategic position in the integration of the solar industry
supply chain.

Being a major supplier to renowned solar cell companies around the world,
M.Setek boasts leading technologies in Japan for upstream polysilicon and
wafers with high conversion rates. It is one of the few global suppliers that
can provide high quality and high-efficiency solar wafers. The Company is
also among the first to employ diamond wire sawing and is capable of mass
production. The technology helps increase conversion rates, eliminate the use
of organic solvents to ensure eco-friendly production, and maintain cost
competitiveness. M.Setek is also equipped with the technologies to fully
recycle its materials, to take their share of responsibility in carbon
balance in the green energy industry. At the PV EXPO, M.Setek will display
several wafers, among which the N-Type mono-crystalline wafer can be applied
to the making of high-efficiency solar cells, with a conversion rate as high
as 20-23%.

James Chen, AUO's Senior Associate Vice President of the Solar
Photovoltaic Business Unit will be speaking at the Taiwan Photovoltaic
Industry Forum on the morning of March 4 during PV EXPO. The topic is to be
AUO's Green Solutions.

AUO has actively invested in solar business and planned for the solar
value chain from upstream to downstream. The Company has partners in Europe
for the development of several solar projects. In addition, a reliability lab
for the testing of solar modules has been set up in Taichung, with its
product quality certified by TUV Rheinland, a global leader in independent
testing and assessment services from Germany. The plan is to next launch
solar business operating points in China this year. With the strategy to
provide total solutions, AUO will cooperate closely with partners in the
industry value chain to further develop the global solar market.
