Abstract:
1. A manufacturing method of an organic light emitting device, comprising the steps of: preparing an optically-transparent substrate formed with an optically-transparent electrode; forming an emission layer on the optically-transparent electrode; forming an organic layer on the emission layer, said organic layer having unevenness formed on a surface of the organic layer, and forming a light reflective electrode on said surface of the organic layer, wherein the unevenness is formed by giving variations to a film thickness of the organic layer so as to form the organic layer unevenly, the organic layer includes projected portions and recessed portions formed by giving the variations to the film thickness of the organic layer, and a film thickness at each of the projected portions of the organic layer is thicker than a film thickness at each of the recessed locations of the organic layer.
