ABSTRACT:
A projection-type display device for producing a synthesized symmetrical projected image. The device includes three liquid crystal light valves associated with the three primary colors producing three separate images. One of the light valves is horizontally scanned in a direction opposite to the horizontal scanning direction of the other two light valves. The two images produced by the light valves which scan in the same horizontal direction are mirror images of the image produced by the third light valve.
