SEOUL, Aug 12 (Reuters) - Shares of South Korean and Taiwanese LCD makers jumped while Japanese rival Sharp (6753.T) fell on Wednesday after an earthquake disrupted glass production in Japan, stoking concerns shortages may intensify.
A shortage in glass substrates has constrained output in the liquid crystal display (LCD) sector and pushed up panel prices as glass suppliers have been slow to boost production after a slump in flat panels last year.
The display industry is recovering from one of its worst downturns as billions of dollars from China’s stimulus package and resilient North American markets help boost demand for televisions and computers.
“Glass supply was already tight and this quake will contribute even more to that. This is good news for LG Display as a lead maker of LCDs,” said Moon Hyun-sik, an analyst at Meritz Securities.
U.S. speciality glass maker Corning Inc (GLW.N) said on Tuesday it has halted production of LCD glass at a factory in Japan, warning the shutdown would result in a 5 to 10 percent decline in the volume of glass shipments in the third quarter from the second quarter. [ID:nN11525861]
Shares in LG Display Co Ltd (034220.KS), the world's second-biggest LCD panel maker, rose 2.1 percent by 0330 GMT in a broader market down .KS11 1.5 percent. LG Display is up 67 percent so far this year.
More than 78,000 shares were traded in AU, 1.3 times the average daily volume over the past 30 days, while over 3.5 million shares changed hands in LG Display, nearly matching the stock’s average daily volume.
Shares in Sharp, Japan’s only major LCD supplier, however fell 3.5 percent as it was expected to be directly affected by the stoppage at Corning’s plant in Japan.
Analysts and fund managers asid LCD shares were set to gain further, thanks to sustained demand and deep shortages of glass production.
“With the glass supply disruption, we see delay in normalisation of supply-demand at least until November,” Nomura analyst James Kim said and upgraded his view on the display sector to “neutral” from “bearish.”
Kim said output from Sharp’s key eight-generation production line would be cut by 70 percent during the outage, “which should cut the global supply by 3 percent on a monthly basis.”
He said he would review the earnings forecasts of LG Display, Au Optronics and Chi Mei.
The shortages could be particularly bullish news for Taiwanese makers, many of whom currently play second fiddle to bigger manufacturers and have suffered several straight quarterly losses.
“There seems to be no let-up in demand for LCD panels,” said Michael On, who manages $40 million on behalf of Beyond Asset Management.
“I see the glass shortage as helping LCD makers improve their margins, which could lead to better-than-expected results this quarter.”
Last week, an LG Display executive told Reuters he expected the uptrend in some PC screen prices to continue into October as the glass shortage was expected to linger through September.
