Organic electroluminescent element

An organic electroluminescent element comprising a pair of electrodes composed of a positive electrode and a negative electrode and a light emitting layer disposed between the pair of electrodes, in which

• the light emitting layer comprises at least one of a polycyclic aromatic compound represented by the following general formula (1) and a polycyclic aromatic compound multimer having a plurality of structures represented by the following general formula (1), and an anthracene-based compound represented by the following general formula (3)
• (In the above formula (1),
• ring A, ring B and ring C each independently represent an aryl ring or a heteroaryl ring, while at least one hydrogen atom in these rings may be substituted,
• Y1 represents B,
• X1 and X2 each independently represent N—R, R of the N—R is an optionally substituted aryl, an optionally substituted heteroaryl or alkyl, R of the N—R may be bonded to the ring A, ring B, and/or ring C with a linking group or a single bond,
• at least one hydrogen atom in a compound or a structure represented by formula (1) may be substituted by a halogen atom or a deuterium atom)
• (In the above formula (3),
• X's each independently represent a group represented by the above formula (3-X1), (3-X2), or (3-X3), a naphthylene moiety in formula (3-X1) or (3-X2) may be fused with one benzene ring, a group represented by formula (3-X1), (3-X2), or (3-X3) is bonded to an anthracene ring in formula (3) at *, two X's do not simultaneously represent a group represented by formula (3-X3), Arl, Are, and Ar3 each independently represent a hydrogen atom (excluding Ar3), a phenyl, a biphenylyl, a terphenylyl, a quaterphenylyl, a naphthyl, a phenanthryl, a fluorenyl, a benzofluorenyl, a chrysenyl, a triphenylenyl, a pyrenylyl, or a group represented by the above formula (4), at least one hydrogen atom in Ar3 may be further substituted by a phenyl, a biphenylyl, a terphenylyl, a naphthyl, a phenanthryl, a fluorenyl, a chrysenyl, a triphenylenyl, a pyrenylyl, or a group represented by the above formula (4),
