ORGANIC ELECTROLUMINESCENT DEVICE |
摘要 |
An organic electroluminescent device 10 has an anode 14, a cathode 18 disposed facing the anode, and an organic layer 16 that is sandwiched between the anode and the cathode and that includes at least a light emitting layer, wherein the light emitting layer includes a light emitting material having electron transportability, a host material having hole transportability and an electrically inert material, and the concentration of the light emitting material having electron transportability gradually decreases from the cathode side toward the anode side. Preferably, the concentration of the electrically inert material also gradually decreases from the cathode side toward the anode side. |
