OG exemplary drawing
1. 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 which is arranged between the electrodes and which includes a light emitting layer;
wherein the organic layer contains a compound expressed by general formula (1) in at least one layer:

OG Complex Work Unit Drawing
wherein in general formula (1), the two X's represent the same linking group, and either both represent oxygen atoms or both represent sulfur atoms, R1 through R10 independently represent a hydrogen atom or a substitution group, and R1 through R10 may jointly form a ring; however, if the two X's represent sulfur atoms, at least one of R2, R3, R5, and R6 represents a substitution group.
