Abstract

An organic electroluminescent element comprising: 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. At least one of the organic layer contains a compound of general formula (1): A-(B)n-D, wherein A, D, and B represent groups of the following general formulas (2), (3), and (4) respectively; n represents 0 or 1; and when n is 0, A and D are not symmetrical about a point to each other, including the binding sites:wherein XA1 to XA11, XD1 to XD11, and XB1 to XB11 are as defined in the specification.
