| description | An organic EL device includes at least a light-emitting layer provided between a pair of electrodes. The light-emitting layer includes at least a hole transporting host material and an electron transporting phosphorescent material, and the concentration of the electron transporting phosphorescent material in the light-emitting layer decreases from a cathode side toward an anode side. |
