ABSTRACT:
In a backlight which arranges light emitting diodes on a side surface of a light guide plate, even when the light emitting diodes having a thickness larger than a thickness of the light guide plate are used, it is possible to manufacture the light guide plate with high accuracy by injection molding. In a liquid crystal display device having a backlight which radiates light to a liquid crystal panel, LEDs are mounted on the light guide plate formed on the backlight as a light emitting element, and an S-shaped inclined portion whose thickness is not changed is formed on the light guide plate from a light incident surface to a light emitting surface of the light guide plate. Since the thickness of the inclined portion is not changed, it is possible to make the pressure of resin flow at the time of performing injection molding uniform thus manufacturing the light guide plate with high accuracy.
