Abstract:
An organic electroluminescence device includes: an anode; an emitting layer; and a cathode, the emitting layer containing a first material, a second material and a third material, the first material being a fluorescent material, the second material being a delayed fluorescent material, the third material having a singlet energy larger than a singlet energy of the second material.

Claim (Index 17):
The organic electroluminescence device according to  claim 12 , wherein the moiety represented by the formula (32) is in a form of at least one group selected from the group consisting of formulae (35), (36), (37), (38), (39) and (30a) below and contained in the third material,\n aromatic hydrocarbon group having 6 to 30 ring carbon atoms, and a substituted or unsubstituted heterocyclic group having 5 to 30 ring atoms, the substituted or unsubstituted aromatic hydrocarbon group having 6 to 30 ring carbon atoms being a non-fused ring;\n Y 39  in the formulae (35) and (36) represents a nitrogen atom; \n Y 39  in (37) to (39) and (30a) represents NR 33 , an oxygen atom or a sulfur atom, R 33  being a substituent that is selected from the group consisting of a cyano group, a substituted or unsubstituted alkyl group having 1 to 20 carbon atoms, a substituted or unsubstituted cycloalkyl group having 3 to 20 ring carbon atoms, a substituted or unsubstituted alkoxy group having 1 to 20 carbon atoms, a substituted or unsubstituted aryloxy group having 6 to 30 ring carbon atoms, a substituted or unsubstituted alkylthio group having 1 to 20 carbon atoms, a substituted or unsubstituted arylthio group having 6 to 30 ring carbon atoms, a substituted or unsubstituted alkylsilyl group having 3 to 50 carbon atoms, a substituted or unsubstituted arylsilyl group having 6 to 50 ring carbon atoms, a substituted or unsubstituted aromatic hydrocarbon group having 6 to 30 ring carbon atoms, and a substituted or unsubstituted heterocyclic group having 5 to 30 ring atoms, the substituted or unsubstituted aromatic hydrocarbon group having 6 to 30 ring carbon atoms being a non-fused ring; and \n wavy lines in the formulae (35) to (39) and (30a) each show a bonding position with another atom or another structure in the molecule of the third material.
