ABSTRACT:
Light emitted from a light source is separated into ordinary light and extraordinary light by a polarization separation element including a polarized light synthesizing device. The ordinary light is regulated in a direction of the polarization plane by a phase difference plate provided on an aperture member so that the polarization plane becomes the same as the extraordinary light. The lights are then converted into a parallel luminous flux through a condenser lens, and then selectively passed through a liquid crystal panel in accordance with an image so that a large image plane of the image is displayed on a screen.
