Taiwan's AU Optronics, the world's No.3 LCD maker, said on Tuesday it returned to profit in the first quarter from a year-ago loss as strong demand for flat-screen TVs lifted prices for its displays.

The profit was well ahead of market expectations but fell short of a record in the fourth quarter, when consumers bought more computers and flat-screen TVs that use liquid crystal displays (LCDs) in the run-up to Christmas.
