    - Revenue of NT$467,158 million, up 30% year-over-year
    - Net income of NT$7,408 million

"Owing to the lower-than-expected TV panel prices, inventory control by
the customers, and the currency influence of NT dollar appreciation, AUO's
operating performance in the fourth quarter of 2010 fell short of
expectations. Fortunately, the Company maintained profitable throughout the
year of 2010," said Mr. Andy Yang, Chief Financial Officer of AUO. "As the
Company proactively adjusted the capacity utilization rates in the fourth
quarter, our quarter-end inventory amounts were able to decrease
sequentially. The Company's EBITDA margins also maintained a leading
position. In addition, the Company's inventory turnover days remained at 40
days at the end of the fourth quarter, the same as those in the previous
quarter."

Looking into the first quarter of 2011, as customers' inventory
adjustments gradually come to an end, demands are expected to gradually
recover. The Company's panel shipments and capacity utilization rates are
also expected to improve quarter over quarter. At the same time, AUO will
continue to implement the "value-oriented" business strategy in 2011. For
example, leading-edge technologies to produce 3D panels, touch modules, OLED
displays and other high-end, value-added products are anticipated to enter
mass production this year. On the other hand, the Company will continue to
strengthen the strategic alliance with customers, and hope to improve the
product profitability as well as asset turnover ratios, which could
eventually contribute to a better return on equity (ROE).
