The figure reflects the impact of another quarter of red ink at LG.Philips LCD, its 38%-owned LCD joint venture with Dutch Philips, which last week posted 169 billion won in net loss amid a seasonal supply glut. Operating profit came in at 172.9 billion, much larger than a forecast for 77.9 billion, swelled by strong sales of premium mobile phones. Sales improved to 6.03 trillion won from 5.8 trillion a year ago. Shares in LG, which has a market value of $10 billion, closed 1.8% lower at 63,300 won. The stock surged 16.7% in the first quarter, beating the KOSPI's 1.3% rise. The display division posted an operating loss margin of 16%, compared with a profit margin of 2% a year ago and bigger than the fourth quarter's 12% loss. Analysts say plasma makers have no clear solution but to wait for the industry standard to move to the 50-inch-and-bigger category, where PDPs should have a price advantage.
