A plurality of LEDs emit light to a right end surface of a light guide plate. The light guide plate emits the light from a front surface, the light being made incident on the right end surface. The heat dissipater dissipates heat generated by the plurality of LEDs. A backlight chassis supports the light guide plate. The backlight chassis includes: a cover plate for covering a rear surface of the light guide plate; and an upper wall connected to the cover plate, for covering an upper end surface of the light guide plate adjacent to the right end surface. The heat dissipater includes a right side wall for covering the right end surface of the light guide plate. The right end of the upper wall of the backlight chassis and the upper end of the right side wall of the heat dissipater are connected by a non-transparent connecting part.
