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.
