Safe Harbor Notice

The statements included in this presentation that are not historical in nature
are "forward-looking statements" within the meaning of Section 27A of the United
States Securities Act of 1933 and Section 21E of the United States Securities
Exchange Act of 1934. These forward-looking statements, which may include
statements regarding AU Optronics' future results of operations, financial
condition or business prospects, are subject to significant risks and
uncertainties and are based on AU Optronics' current expectations.

Actual results may differ materially from those expressed or implied in these
forward-looking statements for a variety of reasons, including, among other
things: the cyclical nature of our industry; our dependence on introducing new
products on a timely basis; our dependence on growth in the demand for our
products; our ability to compete effectively; our ability to successfully expand
our capacity; our dependence on key personnel; general economic and political
conditions, including those related to the TFT-LCD industry; possible
disruptions in commercial activities caused by natural and human-induced
disasters, including terrorist activity and armed conflict; and fluctuations in
foreign currency exchange rates.

Beginning on January 1, 2013, we have adopted the International Financial
Reporting Standards as issued by the International Accounting Standards Board
("IFRS") to the extent endorsed by the ROC Financial Supervisory Commission
("FSC") ("Taiwan IFRS") for reporting our annual and interim consolidated
financial statements in the ROC in accordance with the requirements of the FSC.
All financial information contained herewithin is presented in conformity with
Taiwan IFRS. Readers should be cautioned that Taiwan IFRS differs in many
material respects from accounting principles generally accepted in the Republic
of China ("ROC GAAP"), the United States of America ("US GAAP"), and IFRS
including to the extent that any new or amended standards or interpretations
applicable under IFRS may not be timely endorsed by the FSC. We have
historically presented our consolidated financial statements in accordance with
ROC GAAP, including our consolidated financial statements for the year ended
December 31, 2012. Consequently, the selected comparison financial information
to be included in our quarterly earning releases in 2013 may differ materially
from those released historically.

Our release of financial forecasts and forward-looking statements at any
particular time does not create any duty of disclosure beyond that which is
imposed by law, and we expressly disclaim any obligation to publicly update or
revise any forecasts or forward-looking statements, whether as a result of new
information, future events or otherwise.

Additional information as to these and other factors that may cause actual
results to differ materially from AU Optronics' forward-looking statements or
some of the major differences between ROC GAAP and US GAAP, IFRS or Taiwan IFRS
can be found in AU Optronics' Annual Report on Form 20-F with respect to the
year ended December, 2012 filed with the United States Securities and Exchange
Commission.
