Abstract:
A liquid crystal light valve comprising:a semiconductor substrate having a region for a plurality of switching elements formed in a matrix form on a surface thereof;a first metal layer formed on said surface of said semiconductor substrate through an insulating layer and divided into a plurality of parts by first slits;a second metal layer formed on said first metal layer through another insulating layer and divided into a plurality of parts by second slits;an opposite substrate having an opposite electrode on a surface thereof, disposed so as to be opposite to said second metal layer through an interval on said opposite electrode side;liquid crystal filling said interval between said opposite electrode and said second metal layer; andan n conductivity type region and a p conductivity type region adjacent thereto disposed at a place where light projected from said opposite substrate side through said first slits and said second slits arrives at said semiconductor substrate, both said n conductivity type region and said p conductivity type region being connected with a reference potential.
