ABSTRACT:
In a liquid crystal display device which uses light emitting diodes as a light source, a backlight can efficiently house a heat radiation plate even when an area of the heat radiation plate is increased by taking the radiation of heat from the light emitting diodes into consideration. Light emitting diodes are arranged on a metal substrate to form a plate-shaped light source portion. A heat radiation effect is enhanced by adhering a heat radiation plate to the plate-shaped light source portion. The heat radiation plate to which the plate-shaped light source is adhered is constituted as a housing casing thus efficiently housing the heat radiation plate. A problem which occurs due to the use of the metal-made housing casing can be overcome by mounting a resin-made light guide plate fixing member on the housing casing.
