Abstract

Selection transistors and drive transistors are formed in individual pixel areas on a substrate. Cathode electrodes which reflect visible light are formed above the selection transistors and the drive transistors so as to cover the pixel areas, with flat insulation films between the cathode electrodes and the selection and drive transistors. An organic EL layer and an anode electrode are sequentially formed on the cathode electrodes.
