Projection type display apparatus

Abstract

In order to provide a noise-free reliable projection type display apparatus which has no movable portion and can display a high quality full-color image, the following arrangement is proposed. In a projection type display apparatus which has an optical modulation device for displaying an image by controlling the reflected state of light, illumination units (1R, 1G, 1B) for irradiating the optical modulation device with R, G, and B color light components, and a projecting optical system for projecting reflected light components of the light components with which the optical modulation device is irradiated, and projects and displays an image formed by the optical modulation device, as the optical modulation device, a mirror array device for modulating light by controlling the tilt amounts of mirrors that form pixels is used. The mirror array device is illuminated with the R, G, and B color light components from different directions, and at least some of the reflected light components are guided to the projecting optical system. These some of the reflected light components are made incident on a screen through the projecting optical system.
