摘要：
An organic electroluminescence device having high light emitting efficiency and improved reliability is provided. The organic electroluminescence device includes: an anode containing at least aluminum (Al); a cathode; and an organic layer between the anode and the cathode, the organic layer including a light emitting layer. The organic layer has a hole injection layer composed of a sulfonic acid derivative between the anode and the light emitting layer.
