| Zusammenfassung: | To provide an organic electroluminescent element capable of suppressing a significant increase in a driving voltage while suppressing a short circuit.SOLUTION: The organic electroluminescent device includes: a first electrode; an organic layer including an organic light-emitting layer; an interface adjustment layer; a resistance layer; and a second electrode, in this order. The resistance layer has specific resistance larger than that of the second electrode. The interface adjustment layer has specific resistance larger than that of the second electrode and has specific resistance smaller than that of the resistance layer.SELECTED DRAWING: Figure 1
【課題】短絡を抑えつつ、駆動電圧の大幅な上昇を抑えることの可能な有機電界発光素子を提供する。【解決手段】本開示の一実施の形態の有機電界発光素子は、第１電極、有機発光層を含む有機層、界面調整層、抵抗層および第２電極をこの順に備えている。抵抗層は、第２電極よりも比抵抗の大きな層であり、界面調整層は、第２電極よりも比抵抗が大きく、抵抗層よりも比抵抗が小さな層である。【選択図】図１ |
