ABSTRACT:
In an EL element having an anode, an insulating film (bump) formed on the anode, and an EL film and a cathode formed on the insulating film, each of a bottom end portion and a top end portion of the insulating film is formed so as to have a curved surface. The taper angle of a central portion of the insulating film is set within the range from 35° to 70°, thereby preventing the gradient of the film forming surface on which the EL film and the cathode are to be formed from being abruptly changed. On the thus-formed film forming surface, the EL film and the cathode can be formed so as to be uniform in thickness, so that occurrence of discontinuity in each of EL film and the cathode is prevented.
