摘要： The invention provides a technique for reducing unevenness in brightness and color of images to be displayed in a projector. 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 302Bo on at least one of the light incident side and the light emergent side, and the polarizer is stuck on a flexible and transmissive plate material 308 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.
