ABSTRACT:
An illuminating device achieves higher brightness by improving the utilization efficiency of light from a light source in an illuminating device for emitting plane-shaped light. The backlight device includes a light guide member, and LED units facing side surfaces of the light guide member, and propagates light that is emitted by the LEDs and made incident to the side surfaces in the light guide member so as to emit plane-shaped light from a first main surface of the light guide member. The backlight device includes an insulating reflective member placed outside a second main surface of the light guide member facing the first main surface, and a metal reflective sheet laminated on the insulating reflective sheet on the side opposite to the light guide member.
