Abstract:
1. An organic electroluminescence element comprising: a substrate; a first electrode arranged on a first surface side of the substrate; a second electrode arranged on the first surface side of the substrate so as to face the first electrode; and a functional layer interleaved between the first electrode and the second electrode, the functional layer including a light emission layer, wherein the resistivities of the first electrode and the second electrode are less than the resistivity of transparent conducting oxide, respectively, wherein the functional layer includes a carrier injection layer as the outermost layer, the carrier injection layer being located on the second electrode side of the light emission layer, wherein the second electrode is provided with an opening for extracting light emitted from the functional layer, wherein a conductive layer is formed in the opening so as to be in contact with the second electrode and the functional layer, the conductive layer being optically transparent, wherein the second electrode is covered with the conductive layer, and wherein the carrier injection layer is provided with a recess in the projection domain of the opening.
