ABSTRACT:
The image display apparatus of the invention includes: an image projector for projecting a plurality of optical images having image information for a color display in a juxtapositional color mixture state; and a direct-viewing type screen including two opposed faces, wherein the plurality of optical images projected from the image projector onto one of the two opposed faces of the screen vary optical characteristics of the other of the two opposed faces so as to write the image information for a color display; and the written image information for a color display is read out by utilizing surrounding light from the other face, thereby performing a color display.
