Abstract:
1. A method of manufacturing an organic EL device including a plurality of organic EL elements that are arranged on a substrate, the plurality of organic EL element including an organic light-emitting layer interposed between an anode and a cathode, and a connection terminal disposed on the substrate, the method comprising: forming a sealing layer by covering the plurality of organic EL elements and the connection terminal such that the plurality of organic EL elements lie between the substrate and the sealing layer; forming an organic layer that is formed above the sealing layer; patterning the organic layer in such a manner that an opening extending up to the sealing layer is formed in a portion of the organic layer, which overlaps the connection terminal; and etching the sealing layer in such a manner as to expose at least one part of the connection terminal with the pattern-formed organic layer serving as a mask.
