ABSTRACT:
A front light including a light-guiding plate for receiving light from a light-entering surface and emitting the light from a light-emitting surface, an intermediate light-guiding body disposed along the light-entering surface, light-emitting elements disposed at longitudinal ends of the intermediate light-guiding body. A side surface of the intermediate light-guiding body adjacent to the light-entering surface of the light-guiding plate is a light-emitting surface for emitting light from the light-emitting elements to the light-guiding plate. A side surface opposite to the light-emitting surface is a reflective surface. The total length of the intermediate light-guiding body and the light-emitting elements is the same as the width of the light-guiding plate, the length of at least the light-emitting surface of the intermediate light-guiding body is the same as the width of the light-guiding plate, and the length of the reflective surface is smaller than the length of the light-emitting surface.
