Abstract:
An organic electroluminescent element includes a layer having a shallower LUMO and a higher T1 than those of the first light-emitting layer on the anode side of the first light-emitting layer, and a layer which satisfies at least one of a deeper LUMO and includes a lower T1 than those of the second light-emitting layer on the anode side of the second light-emitting layer, and provides the organic electroluminescent element capable of suppressing the lowering of display quality.
