Abstract:
1. A liquid crystal light valve for a projection type display comprising: a semiconductor substrate on one surface of which a region of switching elements is formed and a plurality of pixels are formed in a matrix form; a first metal layer formed on said one surface of the semiconductor substrate through an insulating layer, said metal layer being divided into a plurality of metal layers by first slits; a second metal layer formed on said first metal layer through an insulating layer and including a shading layer formed so as to cover the entire surface of said plurality of pixels and one intermediate electrode electrically isolated from said shading layer by second slits within said pixel; a third metal layer formed on said second metal layer through an insulating layer and divided into a plurality of metal layers by third slits; an opposite substrate including opposite electrodes on one surface thereof, said opposite electrodes opposing to said third metal layer with a spacing; and a liquid crystal filled in the spacing between said opposite electrode and said third metal layer; said intermediate electrode of said second metal layer being electrically connected with said first metal layer and said third metal layer through though-holes; said shading layer of said second metal layer being electrically isolated from said first metal layer and said third metal layer; and said second slits being staggered from said first slits and said third slits in a direction along the surface of said semiconductor substrate.
