摘要 |
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. A diffusion plate has a curved surface substantially equal to the display screen. By mounting respective optical sheets on the diffusion plate, predetermined curved surfaces are imparted to the respective optical sheets. Due to such constitution, it is possible to realize a liquid crystal display device having a curved surface without using a complicated optical system.
