An organic electroluminescence element includes an anode and a transparent electrode cathode. An organic luminescent layer is located between the anode and the cathode. An electron injection layer is located between the cathode and the organic luminescent layer, and includes at least one of an alkali metal and an alkali earth metal to inject electrons into the organic luminescent layer. A cathode buffer layer is located between the electron injection layer and the cathode, and includes a hole-transporting organic material.
