ORGANIC LIGHT EMITTING ELEMENT, PRODUCTION METHOD OFORGANIC LIGHT EMITTING ELEMENT, IMAGE FORMING DEVICE, AND DISPLAY UNIT

摘要

With a conventional organic light emitting element, a pixel formation accuracy is controlled by the pattern formation accuracy of an electrode provided on the top surface of an organic layer. Since this electrode pattern is formed after an organic layer is formed, a vapor deposition method with a low pattern formation accuracy only is available to make it difficult to form homogenous and fine pixels. A method of producing an organic light emitting element in this invention forms an organic layer covering transparent electrodes exposed by removing those portions of a metal layer corresponding to pixels in a first electrode consisting of a transparent electrode and the metal layer, and forms a second electrode on the organic layer, with a pixel formation accuracy depending on only a metal layer removing accuracy. Since the metal layer is removed before the organic layer is formed, a photolithographic technique can be applied to enable homogenous and fine pixels to be formed.
