Abstract
A backlight device includes LEDs, a light guide plate, and a heat dissipation member. The light guide plate includes edge surfaces including a light entrance surface through which light from the LEDs enters, a front plate surface as a light exit surface through which the light from the LEDs exits, and another plate surface as an opposed surface on an opposite side from the light exit surface. The heat dissipation member having heat dissipating properties includes a bottom plate portion extending along the opposed surface on an opposed surface side, and an upstanding portion extending from the bottom plate portion toward the light exit surface. The bottom plate portion includes projections projecting toward the light exit surface and facing short-side edge surfaces of the light guide plate. The projections are stopped at the corresponding edge surfaces to restrict a distance between the LEDs and the light entrance surface.
