Abstract:
In the present invention, a diffusing sheet for diffusing light outputted from a light guide plate is extended to a stepped upper surface of an LED substrate and disposed at a lateral surface of the light guide plate so that the diffusing sheet can completely cover the light guide plate, thereby preventing undiffused light from being supplied to an liquid crystal display device.
