摘要：
An organic electroluminescence element including an organic layer including a light-emitting layer disposed between a pair of electrodes, wherein the light-emitting layer contains at least one hole transporting light-emitting material and at least one electron-transporting host material, and a concentration of the hole transporting light-emitting material in the light-emitting layer decreases from an anode side toward a cathode side.
