发明名称 Liquid crystal display device
摘要 To prevent, in a backlight where light emitting diodes are arranged on a side surface of a light guide plate, light leakage from a reflection sheet and reduce non-uniformity of emission light from the backlight. In a liquid crystal display device that includes a backlight that irradiates a liquid crystal panel with light, LEDs are disposed as light emitting elements on a light guide plate that is disposed in the backlight, a reflection sheet that comprises a multilayer film is disposed on a bottom surface of the light guide plate, projections are disposed by sandblasting on the bottom surface of the light guide plate in the vicinity of the LEDs, and tight adhesion between the reflection sheet and the light guide plate is prevented. In the vicinity of the LEDs, in order to counter light non-uniformity, reflecting grooves are not disposed and it is a mirror surface, but tight adhesion can be prevented by disposing the projections.
