Provided is a light guide plate including: a diverging portion which is provided on an opposite side of a light exit surface from which light is emitted, the diverging portion causing a luminous flux emitted from a light emitting element to diverge; and a restricting portion which is provided, when a prescribed range from the light emitting element on the light exit surface is defined as an illuminated area illuminated by the light emitting element, in at least a periphery of the illuminated area on the light exit surface and which deflects or shields light traveling from inside toward outside of the illuminated area to restrict traveling, toward a side of the light exit surface, of light traveling toward the outside of the illuminated area.
A light guide plate, comprising:
A planar light source comprising a light emitting element, and a light guide plate which guides light emitted from the light emitting element the light guide plate comprising a light exit surface comprising a side from which the light is emitted, a range of the emitted light comprising an illuminated area caused by the light emitting element, the planar light source apparatus further comprising:
