ILLUMINATION DEVICE, AND LIQUID CRYSTAL DISPLAY DEVICE

摘要

The present invention provides an illumination device which efficiently releases the heat generated from an LED element and prevents the life property of the LED element from deteriorating and the luminance efficiency from dropping; and a liquid crystal display device provided with said illumination device. The illumination device of the present invention is provided with: a substrate attached with a light-emitting element; a heat-releasing plate; and a substrate locking plate. The substrate is attached to one of the surfaces of the heat-releasing plate, the heat-releasing plate has a chamfered notch on the edge of the surface on the opposite side of the surface to which the substrate is attached, and the surface of the heat-releasing plate on the opposite side of the surface to which the substrate is attached is joined to the substrate locking plate.
