Patent ID: 6919680

Claim:
A manufacturing method for a display which uses an organic EL element in a display portion, comprising the steps of: preparing a circuit substrate with microstructures made with drive circuits for said organic EL element set at positions corresponding to pixels, a protective film made of an insulating material covering the microstructures, the protective film having through holes, and with wiring formed on the surface connecting to the microstructures through the through holes; separately preparing a transparent substrate with a transparent electrode layer common with the pixels laminated on the surface, forming an insulating layer with openings therein separated by banks of insulating material on the transparent electrode layer, and forming an emissive layer containing an organic EL layer and a cathode layer in the openings in the insulating layer at positions corresponding to said pixels, the cathode layer having a protruding portion protruding from each of the openings, in which a concave portion is formed on a surface of the protruding portion at an area corresponding to each of the pixels, a part of the protruding portion covering a part of the banks; and then sticking together said circuit substrate and said transparent substrate with the side on which said wiring of said circuit substrate is formed and the side on which said cathode layer of said transparent substrate is formed facing towards the inside.
