Abstract: The present invention provides a top emission-type organic EL element with low resistance, whose upper electrode transmits visible light. The organic EL element includes an electron-transport layer, a light-emitting layer, a hole-transport layer and an upper electrode functioning as an anode formed in that order on a lower electrode functioning as a cathode. The upper electrode, which transmits visible light, includes a transparent electrode layer, a metal electrode layer and a transparent electrode layer, layered in that order from the lower electrode side. The present invention provides a top emission-type organic EL element with low resistance, whose upper electrode transmits visible light. The organic EL element includes an electron-transport layer, a light-emitting layer, a hole-transport layer and an upper electrode ...more ...less
