ABSTRACT:
A projection apparatus and image display apparatus. The apparatus includes a three-color light source that emits a plurality of color lights having different wavelengths, and a diffraction type optical element that performs diffusion forming of individual color lights. A field lens makes the diffusion-formed individual color lights into parallel lights, and a liquid crystal panel has a microlens array with a plurality of microlenses arranged in a matrix at the incident regions of the individual parallel color lights. A pixel section has three pixel openings arranged oppositely to the individual microlenses.
