Abstract

PURPOSE:To allow a user to visually view images even in a bright atmosphere due to disturbance light by stretching a polarizing filter on the side of the reflecting surface of a screen so that the polarizing filter attains a non-parallel attitude. CONSTITUTION:The polarizing filter 3 is stretched on the side of the reflecting surface 2' of the stereo screen 1 so that the filter can fall naturally in a non- parallel attitude. Namely, a space in a shape of a semi-convex lens is formed between the reflecting surface 2' of the screen 1' and the polarizing filter 3, and they are installed a prescribed distance before an image projector 4 so that prescribed images formed by an electric drive device can be reflected on a liquid crystal panel. Since the disturbance light 7 is not polarized, it is extinguished too much by the reflecting surface 2' to be reflected. Thus, the reflected light of disturbance light cannot be found even if it exists, that it, even if a room is lighted by disturbance light, projected images are sharply viewed.
