"Despite a particularly difficult business environment in 2H 2004, AUO was able to achieve both record sales and net profit for FY 2004, the best performance since the Company's inception and the highest achieved ever in Taiwan's TFT-LCD industry." Said Mr. Max Cheng, Vice President and Chief Financial Officer of AUO Corporation "This performance is attributed to AUO's remarkable execution capability, product mix management, customer portfolio, cost competitiveness, manufacturing capability, technology, R&D and design know-how. As a result, our ROE improved from 16.9% in 2003 to 21.4% in 2004." The management also achieved considerable success in managing production costs and working capital management, which resulted in notable 24.2% reduction in inventory and the inventory turnover days were reduced from 56 days at the end of 3Q04 to 44 days at the end of 4Q04.

AUO's large size panel shipment (10" and above) also posted strong growth, supported by the Company's 5G fab capacity. Shipment of large size panels reached 18.9 million, up 59.0% YoY.

"LCD TV is expected to be a key growth driver for the year 2005." Dr. Hui Hsiung, Executive Vice President of AUO Corporation pointed out. "AUO's LCD TV business will also reflect its well thought out strategy, as revealed by our 48% QoQ growth in LCD TV revenues in 4Q04." The Company is expected to play an important role in the fast emerging LCD TV market, supported by its strong research and development, design capability, product and process technology, and enhanced production efficiency from its G6 fab (1,500 x 1,850mm), which is expected to commence mass production in March 2005 and is expected to reach design capacity of 60,000 substrates per month by the end of 2005. The Company has successfully turned on the first 32"W LCD TV panel in January 2005 by its G6 fab, following its first success of 19" monitor panel by its G6 fab in November 2004. The timely capacity expansion contributed by the Company's G6 fab is expected to be instrumental to its business opportunity in the LCD TV sector.
