AUO SunPower Solar Cell Fab Dedicated

AUO Chairman and Malaysian Prime Minister to Inaugurate New Green Building Design

HSINCHU, Taiwan, December 15, 2010 - AU Optronics Corp. ("AUO" or the "Company") (TAIEX: 2409; NYSE: AUO)
today announced the inauguration of AUO SunPower Sdn. Bhd. ("AUO SunPower")
in Malaysia. The ceremony was attended by AUO Chairman K.Y. Lee, Malaysian
Prime Minister Datuk Seri Najib, SunPower CEO Tom Werner, and Melaka Chief
Minister Datuk Seri Ali Rustam. The construction of the facility will
continue through 2013 and, when completed, is expected to generate more than
1,400 megawatts annually of high-efficiency solar cells to meet world
demands.

AUO SunPower is located in Melaka's "solar valley", south of Kuala
Lumpur, Malaysia. The construction will continue through 2013 and, when
completed, is expected to generate more than 1,400 megawatts annually of
high-efficiency solar cells. The two-building facility will be 108,000 square
meters (more than 1 million square feet), which is approximately the size of
seven U.S. football fields, and will house 28 solar cell production lines
when fully online. In production since October of this year, AUO SunPower has
already produced approximately 5 megawatts with up to 22.5 percent conversion
efficiencies.

"We are pleased to dedicate this facility and celebrate the success of
the AUO SunPower joint venture," said K.Y. Lee, Chairman of AUO. "The AUO
SunPower Fab is already in production, benefiting from our leading
manufacturing technology, and efficiently-run global operations and
management. We welcome Prime Minister Datuk Seri Najib to our facility today,
and thank him and the Malaysian government for their full support of our
joint venture."

AUO SunPower has been recognized by the International Energy Agency for
its superior energy-efficient design. In addition, it has applied for both
gold and silver Leadership in Energy and Environmental Design (LEED)
certifications for its administration building and cell fab, respectively.
AUO SunPower was engineered with a variety of energy efficient features that
will help increase operations efficiency and cut energy costs. These features
include:

    - Solar covered parking, with the system generating up to 2.6
      megawatts of power;
    - Rooftop solar on all site facilities with systems generating more
      than 10 megawatts of power;
    - Rain water retention ponds for environmental protection and water
      recycling;
    - Improved HVAC cooling and heating systems that offer a much lower
      carbon footprint for a facility of this size and type;
    - 100 percent of the hot water heating capacity is generated by
      heat recovery air compressors;
    - Cooling system efficiency that uses approximately 40 percent less
      electricity compared to typical systems in the Melaka area.

"AUO SunPower will enable us to significantly increase the production of
our high-efficiency solar cells in this state-of-the-art manufacturing
facility," said Tom Werner, SunPower CEO. "Malaysia's investment in the AUO
SunPower joint venture, an excellent talent pool and a positive business
investment climate, has given us the opportunity to significantly expand
solar cell production that will meet the demand for solar worldwide, which
has grown nearly eight fold over the past four years. We appreciate our
partnership with the Malaysian government."
