Patent ID: 7498737

Claim:
A method for manufacturing an organic electro-luminescent device, the method comprising the steps of: providing a substrate; arranging at least one first electrode on substrate, the first electrode being made of a first conductive film to form a subassembly; forming a plurality of insulating ribs on the first electrode; forming at least one organic layer on the subassembly, the at least one organic layer being made of an organic electro-luminescent medium, so that the at least one organic layer covers the first electrodes; forming a second conductive film over the at least one organic layer; and removing at least one portion of the second conductive film using a radiation method to create second electrodes that are electrically isolated from each other; wherein removing the at least one portion of the second conductive film includes removing a portion of the second conductive film from over the insulating ribs and removing at least a portion of the insulating ribs.
