Abstract
A LCD device has a LCD panel and a drive TCP for driving the LCD panel. Back light is guided to the rear surface of the LCD panel by a light-conductive sheet. The leakage back light passed the rear surface of the light-conductive sheet is reflected by a reflecting plate having a conductive film at the rear surface of the reflecting plate. The conductive film is connected to a ground pattern of the printed circuit board which transfers signals to the drive TCP. The reflecting plate has both functions for reflecting back light and shielding the LCD panel against the noise generated by the printed circuit board.
