  • Patent number: 9076990
    Abstract: A method of manufacturing an organic EL device according to the present application example includes forming a sealing layer by covering multiple organic EL elements and a connection terminal, forming a color filter as an organic layer that covers the sealing layer, patterning the color filter in such a manner that an opening extending up to the sealing layer is formed in a portion of the color filter, 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 color filter serving as a mask.
