Dell Inc, the world's third-largest PC maker, has filed a lawsuit against Sharp Corp, Hitachi Ltd, Toshiba Corp and two other companies for alleged price fixing of LCD displays.

Dell filed the suit at a U.S. district court in San Francisco on Friday against the group of five firms, which also includes Japan's Seiko Epson and Taiwan's HannStar, a spokesman at Dell's Japan unit said on Monday.

Dell has not decided the level of damages it will seek in the lawsuit, the spokesman said.

Sharp and Hitachi said that they were aware of the suit filed by Dell but declined to comment further. Toshiba and Seiko Epson said they were still making checks on the issue, while no one at HannStar was immediately available for comment.
