Abstract:
A multi-display device comprising:a plurality of projectors for projecting partial images on a screen so that adjoining partial images will overlap to have margins thereof superposed on each other, the plurality of partial images being synthesized to construct one image, and each projector includes an illuminator that radiates light resulting in light source images that are arrayed two-dimensionally, a display that is illuminated with light radiated from the illuminator and displays the partial images, and a projecting optical system that projects light rays, which represent the partial images onto a screen; and a light interceptor that intercepts the marginal part of light to be projected as a partial image, and lowers the luminance in a portion of the partial image to be superposed on a portion of an adjoining partial image so that the luminance in the superposed portion of the overlapping partial images is substantially identical to the luminance in the other portions of the partial images that are not superposed on each other, the interceptor has an intercepting edge that comprises a plurality of parts that are not parallel to the direction of rows of said light source images.
