Beschreibung
Zusammenfassung:	A side-edge type surface light emitting apparatus includes: a light guide plate having a first light emitting surface, a light distribution controlling surface opposing the first light emitting surface and a light incident surface; a light source disposed on the light incident surface; a first prism sheet having multiple first prisms opposing the first light emitting surface and a second light emitting surface opposing the multiple first prisms; a light absorbing sheet opposing the light distribution controlling surface; and a second prism sheet having a flat surface opposing the light distribution controlling surface and multiple second prisms opposing the light absorbing sheet, the multiple second prisms being perpendicular to the light incident surface of the light guide plate.
