Abstract
A projector includes a single light modulator that has a pixel region containing a plurality of pixels, and a pixel shifting device configured to switch the optical path of image light output from the light modulator between a reference optical path and a shifted optical path. A plurality of sub-pixels that are segmented by a black matrix and output light having different colors form each of the pixels in the pixel region of the light modulator. The pixel shifting device positions the image light traveling along the reference optical path at a reference display position on the projection receiving surface, and positions the image light traveling along the shifted optical path at a shifted display position on the projection receiving surface to superimpose the image light output from the sub-pixels at the shifted display position on a region corresponding to the black matrix at the reference display position.
