Reflection type liquid crystal device, manufacturing method therefor, and projection display system

摘要

An active matrix reflective liquid crystal device includes an array substrate which includes switching elements corresponding to pixels and an array of pixel electrodes connected to the switching elements; and an opposing substrate which has a transparent electrode opposite the array of pixel electrodes with a liquid crystal layer inserted therebetween. Each of the pixel electrodes includes an array of electrode studs, (e.g., divided electrode elements). The regions between the electrodes are filled with an insulating material, and the surface of the stud array is planarized by chemical-mechanical polishing (CMP). A dielectric light reflective film is formed on the planarized surface of the stud array, and a liquid crystal molecule alignment film is deposited thereon. Thus, a reflection type liquid crystal device is provided having a planarized light reflective face for a reduced reflection loss, along with a method for manufacturing the same, and a projection display system using such a reflection type liquid crystal device.
