ORGANIC EL DISPLAY PANEL AND MANUFACTURE THEREOF

摘要

PROBLEM TO BE SOLVED: To reduce the resistance of a metal electrode by cutting a metal electrode auxiliary part formed on a bulkhead and consisting of the same material as the metal electrode from the adjacent metal electrode by one side surface of the bulkhead. SOLUTION: An organic EL material layer 3 and a metal electrode 4 are formed successively on one side surface 6A forming a normal taper surface of a bulkhead 6 and the head part 6C of the bulkhead 6 by evaporation. On the other side surface 6B forming the reverse taper surface of the bulkhead 6, the organic EL material layer 3 and the metal electrode 4 are formed separately. The metal electrode 4 is connected to a metal electrode auxiliary part 4A formed on the head part 6C of the bulkhead 6 via the normal taper surface to reduce the resistance of the metal electrode 4. Since the organic EL material layer 3 is formed between a transparent electrode 2 and the metal electrode 4 also in the vicinity of the root of the other side surface 6B that is the reverse tapered surface, the transparent electrode 2 is never short-circuited to the metal electrode 4.
