Abstract
Light that enters from an incident light surface of a light guide plate includes not only light which is guided toward the forward direction in front but also light whose optical path is modified by optical elements while progressing through the inside of the light guide plate, and thus wasteful emission from an emitting surface is inhibited. Lights are guided in a longitudinal direction of the optical elements. Light is diffused in the course over which the lights are guided and the region to which they are guided. The lights are guided by the optical elements in the longitudinal direction of the optical elements, and thereby light diffusivity is exhibited in the region in which the optical elements are provided while controlling the directivity of the light.
