Patent attributes
A projector comprises a light source, an optical system for illumination, a reflective light modulating device having a plurality of reflective elements arranged in matrix form to be illuminated by the light emitted from the optical system for illumination, and an optical system for projection. The optical system for projection includes a reflective surface configured to bend a projection chief ray reflected at the center of the reflective light modulating device among projection chief rays in the optical system for projection. The reflective surface has a predetermined angle to the ray which is emitted from the optical system for illumination and which strikes the center of the reflective light modulating device, and includes a P shaft parallel to one of an X axis and a Y axis along which the plurality of reflective elements is arranged.
