Abstract
A projector includes an illumination system for emitting illumination light, an electro-optical device for modulating light from the illumination system according to image information, and a projection'system for projecting a modulated light beam obtained by the electro-optical device. The electro-optical device has a polarizer on at least one of the light incident side and the light emitting side, and the polarizer is attached to a flexible and transmissive plate material that bends in response to changes in shape of the polarizer. This makes it possible to reduce unevenness in brightness and color of images to be projected and displayed.
