Abstract
A method of fabrication of organic electroluminescent device having an organic electroluminescent layer between a first electrode and a second electrode, including the steps of forming a set of first electrode elements on a principal surface of a support to provide the first electrode, forming an insulation layer to overlie the first electrode elements as well as open regions between the first electrode elements so that the insulation layer defines a substantially smooth top surface, removing a surface portion of the insulation layer to a level sufficient to expose clean top surfaces of the first electrode elements so that the insulation layer and the first electrode have a common top surface, and sequentially forming the organic electroluminescent layer and the second electrode on the common top surface.
