Abstract
The present invention provides a method of manufacturing an organic EL display capable of decreasing the resistance of scanning-side electrodes, and improving the efficiency of utilization of light emitted in organic layers. In the manufacturing method, stripe first electrodes made of a transparent conductive material are formed in parallel on a transparent substrate, and then an insulation layer is formed on the transparent substrate with the apertures formed above the first electrodes. An organic film 24 composed of a film of an organic luminescent material, a second electrode material film and a protecting film is laminated in this order on the transparent substrate to cover the insulation layer, and then independent island resist patterns are formed on the protecting film. Then, a laminated film composed of the organic film, the second electrode material film and the protecting film is etched using the resist patterns as a mask to pattern independent island laminations each composed of an organic layer, a second electrode, and a protecting layer.
