1. A projector comprising:
a light source;
a light modulation panel that has a pixel region containing a plurality of unit pixels segmented by a black matrix and modulates light incident from the light source to generate image light;
a projection system that projects the image light output from the light modulation panel onto a projection receiving surface; and
a pixel shifting device that is disposed between the light modulation panel and the projection system and shifts an optical path of the image light output from the light modulation panel,
wherein one of the plurality of unit pixels in the pixel region is set as a reference unit pixel,
before the optical path is shifted at a reference display position on the projection receiving surface, the pixel shifting device shifts the optical path of the image light output from the light modulation panel to successively switch the optical path between a first shifted optical path that causes the shifted image light to be located at a first shifted display position on the projection receiving surface and a second shifted optical path that causes the shifted image light to be located at a second shifted display position on the projection receiving surface, and
the pixel shifting device superimposes the image light output from the reference unit pixel at the first shifted display position on a region corresponding to a second portion of the black matrix and located at one side of the reference unit pixel at the reference display position,
and surrounding the reference unit pixel at the reference display position in such a way that the image light does not overlap with other unit pixels adjacent to the reference unit pixel out of the unit pixels.
