REFLECTION TYPE LIQUID CRYSTAL ELEMENT, ITS PRODUCTION, AND PROJECTION DISPLAY DEVICE

摘要

PROBLEM TO BE SOLVED: To give a flat light reflection face to reduce the loss of reflected light due to diffraction. SOLUTION: An active matrix type reflection liquid crystal element is provided with an array substrate having switching elements corresponding to picture elements and an array of picture element electrodes 32 connected to switching elements, and a counter substrate which has a transparent electrode facing the array of picture element electrodes 32 with a liquid crystal layer between them. Each picture element electrode 32 is formed so as to have an array of electrode studs, namely, split electrodes 68, Areas between studs are filled with an insulating material 64. The surface of the stud array is smoothed by chemical and mechanical polishing treatment. A dielectric light reflection film is provided on the flat surface of the stud array, and a liquid crystal molecule orienting film is provided on this film.
