Abstract:
An organic electroluminescence device capable of realizing both high light emitting efficiency and high reliability with an inexpensive structure is provided. The organic electroluminescence device includes an organic layer including a light emitting layer between an anode and a cathode. The anode has a laminated structure including a first layer composed of aluminum (Al) or an alloy containing aluminum as a main component and a second layer that is provided between the first layer and the organic layer and is composed of an alloy containing aluminum as a main component, and a resistance of the first layer is lower than a resistance of the second layer.
