By circular or polygonal openings formed in at least one of a metal film, a semiconductor film, an insulating film and the like, which films are below a reflecting electrode, minute irregularities are densely formed on a surface of the reflecting electrode. In this case, it is required that a linear density defined by peripheral dimensions of the openings per unit area is equal to 0.2 or more.
