摘要：
An organic electroluminescent element including a substrate, a pair of electrodes including an anode and a cathode, disposed on the substrate, and at least one organic layer including a light emitting layer, disposed between the electrodes, in which at least one kind of compound represented by the following general formula is contained in any layer of the at least one organic layer, is an organic electroluminescent element, in which the generation of dark spots during driving is inhibited:
