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:
![]() 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.
