Abstract
An organic electroluminescent element includes, in order, a first electrode, an organic layer that includes an organic electroluminescent layer, an interface adjustment layer, a resistive layer, and a second electrode. The resistive layer has a specific resistance higher than a specific resistance of the second electrode. The interface adjustment layer has a specific resistance higher than the specific resistance of the second electrode and lower than the specific resistance of the resistive layer.
