Display device and method of fabricating the display device
First Claim
1. A display device comprising:
- a first electrode on an insulating surface;
an electroluminescence film on said first electrode;
a second electrode on said electroluminescence film; and
a bump selectively formed for covering an end portion of said first electrode, wherein said bump has a bottom end portion contacting with an upper surface of said electrode and a top end portion connecting continuously to a flat upper surface of said bump, wherein a surface of said bottom end portion is rounded, and a surface of said top end portion is rounded.

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.
