20080303976 | Liquid Crystal Display Device - A liquid crystal display panel includes a TFT substrate and a color filter substrate respectively formed of a glass substrate. By housing the liquid crystal display panel in the inside of a frame having a curved surface, a predetermined curved surface is imparted to a display screen. Using a direct backlight having a plurality of fluorescent lamps, distances between the respective fluorescent lamps and the liquid crystal display panel are set to a fixed value.
