An array of pixels in a liquid crystal silicon light valve are fabricated with a minimum of surface topology by forming raised dielectric spacer walls on an underlying array support surface prior to the deposition of the metal pixel electrode layer. Deposition of the metal pixel electrode layer, followed by chemical-mechanical polishing to stop on the top of the spacer walls, produces an electrode surface that is flush with the tops of the dielectric spacer walls. This resulting planarity in the surface of the pixel cell array minimizes surface topology exhibited by the array, maximizing reflectance of the light valve.
