Abstract
A projector includes: a solid-state light emitting element that emits light; a projection image forming unit that includes an effective area in order to form a projection image; and a reflecting member disposed between the solid-state light emitting element and the projection image forming unit, wherein: the reflecting member reflects part of the light emitted from the solid-state light emitting element and thus redirects the part of the light to travel back to the solid-state light emitting element, the part of the light not entering the effective area.
