摘要： The present invention relates to an illumination device (6). When the light from the light emitting element (23) is guided to the first illuminating portion (26) of the light guide plate (24), the light is radiated from the whole upper surface of the first illuminating portion to illuminate the upper surface side of the light guide plate. Also, when the light from the light emitting element (23) is guided to the second illuminating portion (27) of the light guide plate (24), the light is radiated from the whole lower surface of the second illuminating portion (27) to illuminate the lower surface side of the light guide plate (24). The upper and lower surface sides of the light guide plate (24) can be excellently illuminated with one light guide plate.
