摘要： A light source unit includes a first reflector having a reflection face; a second reflector having a reflection face; a plurality of light sources; and a light condensing optical system disposed between the first reflector and the second reflector. Light beams emitted from the plurality of light sources are reflected at a first reflection position on the reflection face of the first reflector, and then reflected at a second reflection position on the reflection face of the second reflector. The second reflection position is close to an optical axis of the light condensing optical system compared to the first reflection position. The light condensing optical system is configured such that the light beam passes through the light condensing optical system at least two times when the light beams reflect between the first reflector and the second reflector.

摘要： A projection optical system includes first and second optical systems. The first optical system includes a transmissive-refractive element and the second optical system includes a reflective-refractive element. An image formed by a spatial light modulator is projected by the projection optical system on a projection surface. A light beam that travels along an optical path that leads from the second optical system to the projection surface in an optical path between a center of the image formed by the spatial light modulator and the projection surface is projected at an angle with respect to a normal to the projection surface. An optical axis of the first optical system is folded to a folded position by an optical path deflecting unit in an area of the first optical system where the light beam entering the optical path deflecting unit is a converging light beam or a substantially parallel light beam.
