ABSTRACT:
A liquid crystal display device includes a display panel, a backlight which radiates light to the display panel, a light emitting element which is mounted on the backlight, and a light guide plate on which light from the light emitting element is incident. The light guide plate has an upper surface and a bottom surface. The bottom surface has grooves formed therein delimited by at least one surface which extends at a slant with respect to the bottom surface. A reflection sheet is provided which reflects the light radiated from the bottom surface. The grooves are formed to produce a first light which is reflected on the grooves and a second light which is radiated from the grooves and is reflected on the reflection sheet, and an asymmetric prism sheet is arranged on the light guide plate.
