Organic electroluminescent device, method for producing organic electroluminescent device, and electronic apparatus
Abstract:
A method for producing an organic electroluminescent device includes forming a first electrode configured to partially cover a substrate, forming an organic light-emitting layer configured to cover the first electrode, forming an optically transparent second electrode that lies on a side of the organic light-emitting layer opposite the side adjacent to the first electrode and is superposed on a current-carrying portion of the first electrode in plan, forming a third electrode in at least part of a region that is not superposed on the current-carrying portion in plan, the third electrode being electrically connected to part of the second electrode, forming an optically transparent protective layer configured to cover at least a region of the second electrode where the second electrode is not superposed on the third electrode in plan, and removing part of the organic light-emitting layer with the third electrode and the protective layer serving as a mask.
