Patent ID: 8334529

Claim:
A method of manufacturing an organic electroluminescence element, comprising: providing an anode metal layer on a substrate, the anode metal layer comprising an inner region and an outer region, the inner region being adjacent to and different than the outer region, an upper surface of the inner region being lower than an upper surface of the outer region; providing a metal oxide layer on the inner region of the anode metal layer; providing a hole transport layer above the metal oxide layer, the hole transport layer comprising a hole-transporting organic material; providing an organic luminescent layer above the hole transport layer; providing a cathode layer above the organic luminescent layer, the cathode layer for injecting electrons into the organic luminescent layer; and providing an insulating layer above the outer region of the anode metal layer after providing the anode metal layer on the substrate; and providing an opening in the insulating layer by partially removing the insulating layer through patterning the insulating layer after providing the insulating layer above the anode metal layer, wherein the metal oxide layer is provided on a surface of the opening through oxidizing the surface after providing the opening.
