Beschreibung
Zusammenfassung:	An illumination device includes a transparent light guide plate having an end face being an incident surface and a bend between the incident surface and a distal end face opposite to the incident surface, and a light source facing the incident surface. The light guide plate includes first prisms on a first surface extending from the incident surface to the bend to reflect light from the light source entering the light guide plate through the incident surface and emit light through a second surface opposite to the first surface, and second prisms on a third surface extending from the distal end face to the bend to reflect light from the light source entering the light guide plate through the incident surface and emit light through a fourth surface opposite to the third surface.
