Abstract: A liquid crystal display device and a method of compensating for a luminance point defect of the liquid crystal display device. After a detective luminance point pixel is detected, a laser beam is irradiated from an excimer laser oscillator on a portion of a surface of one of glass substrates of a liquid crystal panel on which an illuminating light is incident, the portion being located on the same irradiation path of the illuminating light with the luminance point pixel. In this way, the portion is laseretched, thereby forming a rough surface in the portion. When such a panel is used in a projection device, the light transmitted through the luminance point pixel is scattered and so reduced. Accordingly, the defective luminance point pixel is inconspicuous to normal pixels around the defective luminance point pixel.

Abstract: In a liquid crystal display device having pixels arranged in a matrix form, light is allowed to pass or blocked depending upon whether or not a voltage is applied to electrodes each corresponding to the pixels, and the display operation is conducted by controlling the transmission/nontransmission of light. When a conductor or switching element connected to an electrode is broken, it is not possible to apply such a voltage to the respective electrode. Such a pixel is always at the light transmission display state, with the result that the pixel becomes a bright spot, thereby degrading the display quality. Therefore, a blocking piece for blocking light is disposed over the pixel which becomes a bright spot. This prevents the bright spot from appearing, thereby improving the display quality.
