Abstract:
An organic electroluminescent element having a small reduction rate in the luminance immediately after the start of light emission is provided. The organic electroluminescent element includes a substrate, a pair of electrodes including an anode and a cathode, disposed on the substrate, a light emitting layer disposed between the electrodes, and at least one organic layer disposed between the light emitting layer and the anode, in which at least one kind of a specific compound including a fluorene structure is contained in at least one organic layer between the light emitting layer and the anode, and at least one kind of a specific compound including a carbazole structure or a fluorene structure is contained as a light emitting material in the light emitting layer.
