Abstract:
A projection image display apparatus is equipped with a light shielding member for partially shielding the illumination light from the illuminating optical system so as to reduce the image brightness in a region where the intensity of the reflected light reflected between the on-light and off-light becomes strong, and making the intensity of the illumination light emitted to the respective mirror elements uneven.
