A FET is formed on a semiconductor substrate, a curved surface having a radius of curvature is formed on an upper end of an insulation, a portion of a first electrode is exposed corresponding to the curved surface to form an inclined surface, and a region defining a luminescent region is subjected to etching to expose the first electrode. Luminescence emitted from an organic chemical compound layer is reflected by the inclined surface of the first electrode to increase a total quantity of luminescence taken out in a certain direction.
