Abstract
Providing an organic electroluminescence element that can reduce the unevenness of the brightness and can improve the external quantum efficiency. The organic electroluminescence element includes a substrate, a first electrode, a second electrode, a functional layerinterleaved between the first electrodethe second electrodeand including a light emission layer, and a conductive layer. The resistivities of the first electrodeand the second electrodeare less than the resistivity of transparent conductive oxide. The second electrodehas an opening for light extraction. The functional layerincludes, as the outermost layer on the second electrodeside, a carrier injection layer. The conductive layeris optically transparent and is in contact with the second electrodeand the functional layer. The carrier injection layerhas a recess in the projection domain of the opening.
