摘要：
An outer light collecting portion 10 which sticks out of a light emission surface 14 to the light emission direction at the same time when a light guide plate is formed by resin forming with a mold. An area of a surface for collecting outer light is larger than that of a conventional light guide plate so as to collect outer light effectively. Light from a light source which is incidence through a light incident surface 12 reflects from a light reflection surface 13 and two side surface 11 of a light guide plate 1, and is emitted as synthesized light having the even directivity from a light emission surface 14.
