Abstract
In order to achieve a liquid crystal display device for TV with a reduced thickness, light weight, and uniform brightness, a liquid crystal display panel and a backlight are housed in a mold. In the backlight, light emitting diodes are provided in a frame-like flexible wiring substrate, in which plural the light emitting diodes are provided on each of four side surfaces of a light guide panel. A distance between the light emitting diodes in the central portion of each side of the light guide panel is small, while a distance in the corners of each side is large.
Claims7
