Abstract:
A projector comprising:a light source; a sheet polarization beam splitter (PBS) arranged to be inclined with respect to an optical axis on a proceeding path of light emitted from the light source; a reflection display mechanism which generates an image from an incident light polarized in one direction transmitting the sheet polarization beam splitter and transmits said image toward said sheet polarization beam splitter; a relay lens unit arranged on an optical path to guide an incident light by at least one of focusing and diverging said incident light; a correcting mechanism which corrects an aberration of said incident light caused by said sheet polarization beam splitter, said correcting mechanism arranged on a proceeding path of the light generated from the reflection display mechanism and transmitting the sheet polarization beam splitter; and a projection lens unit which magnifies and projects a corrected incident light input from the correction mechanism toward a screen.
