摘要： The present invention provides a liquid crystal display device of high quality having high brightness and uniform brightness distribution by focusing the light radiation direction from a light guide plate in the vertical direction with respect to a light radiation surface of the light guide plate. The liquid crystal display device includes a liquid crystal display panel and a flat lighting device which radiates an illumination light to a back surface of the liquid crystal display panel. The flat lighting device includes a light guide plate which has an upper surface facing a back surface of the liquid crystal display panel in an opposed manner and constituting a light radiation surface and a bottom surface which is arranged opposite to the upper surface. One LED is arranged at a first corner portion of the light guide plate and another LED is arranged at a second corner portion of the light guide plate arranged adjacent to the first corner portion. By forming reflection surfaces which are inclined toward the upper surface from the bottom surface of the light guide plate and inclined surfaces which abut on the reflection surfaces on the lower surface of the light guide plate, the light radiation direction from the light guide plate is focused in the vertical direction with respect to the upper surface of the light guide plate.

摘要： In a liquid crystal display device using a light emitting diode as a light source, even when a plurality of light emitting elements are provided, an inclined surface is formed on a light guide plate as a reflection surface, and a light is converged in the liquid-crystal-panel direction using the reflection surface. In a liquid crystal display device which includes a backlight for radiating a light toward a liquid crystal panel, LEDs are formed on the light guide plate which is mounted on the backlight as light emitting elements. The plurality of LEDs are arranged along a side surface of the light guide plate, and a first reflection surface and a second reflection surface are formed on a bottom surface of the light guide plate. The second reflection surface is arranged closer to the LEDs than the first reflection surface and an angle of the second reflection surface is set larger than an angle of the first reflection surface.

The backlight arranged on a back surface of a liquid crystal panel includes a light guide plate, a light source, a first asymmetrical prism sheet, and a second asymmetrical prism sheet. A reflection surface having an inclination of 2° or less for guiding light from the light source toward the liquid crystal display panel is formed on a back surface of the light guide plate. The first asymmetrical prism sheet and the second asymmetrical prism sheet respectively include projecting portions which extend in the arrangement direction of the light source and are arranged in parallel to each other in the direction which intersects the arrangement direction of the light source.
