An outer light collecting portion,which sticks out of a light emission surface,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,reflects from a light reflection surface,and two side surface,of a light guide plate,and is emitted as synthesized light having the even directivity from a light emission surface
