Abstract

Abstract The present invention relates to an image display device comprising a plurality of image display means for displaying a plurality of bits of time-serial image information from image producing means, shutter means corresponding to the plurality of image display means and transmitting or not transmitting a light beam therethrough, an imaging optical system for imaging the plurality of bits of time-serial image information on the same area on a common imaging plane, and control means for repeating to bring about a state in which only one of the plurality of shutter means transmits a light beam therethrough for a predetermined time with a predetermined time difference to thereby image the plurality of bits of image information successively on the imaging plane.
