摘要：
An organic electroluminescent element is provided that has high luminous efficiency, and a slow luminance deterioration rate in the initial stage of lighting. The organic electroluminescent element includes 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, wherein at least one organic layer includes a compound represented by the general formula (1). (R11 to R15 represent hydrogen atoms, alkyl groups, or silyl groups, and any one of R21 to R24 represents a group represented by general formula (1A) or (1B). Ph4 represents a p-phenylene group, and at least one of Ph4a and Ph4b represents a p-phenylene group.)
