Abstract
The projector apparatus of the invention constructs colored imaging light by splitting a beam of light received from a light source into beams of three primary colors and inputting the beams of three primary colors in an image synthesizing device via light adjusting device. The image synthesizing device includes a prism, a prism mount for fixing the prism, LCPs, and LCP holders integral with the prism mounts for fixing the LCPs. The prism mount has a central area and multiple peripheral areas, each area in contact with the prism. The invention provides effective solution for solving reliability problems encountered in a cost reduction strategy for miniaturization of a prism and for using inexpensive plastic prism fixation members.
