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 23):
The organic electroluminescence device according to  claim 12 , wherein the third material comprises a group represented by a formula (30d) below, where:\n X 31 , X 32 , X 34  and X 36  each independently represent a nitrogen atom or CR 31 ; \n X 41 , X 43 , X 44  and X 45  each independently represent a nitrogen atom or CR 36 ; \n R 31  and R 36  each independently represent a hydrogen atom or a substituent, the substituent being selected from the group consisting of a halogen atom, a cyano group, a substituted or unsubstituted alkyl group having 1 to 30 carbon atoms, a substituted or unsubstituted cycloalkyl group having 3 to 30 ring carbon atoms, a substituted or unsubstituted trialkylsilyl group, a substituted or unsubstituted arylalkylsilyl group, a substituted or unsubstituted triarylsilyl group, a substituted or unsubstituted diarylphosphine oxide group, 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; \n X 32  and X 41  are optionally cross-linked via an oxygen atom, sulfur atom or CR 55 R 56 ; \n X 34  and X 45  are optionally cross-linked via an oxygen atom, sulfur atom or CR 57 R 58 ; \n R 55  to R 58  each independently represent a substituent selected from the group consisting of a halogen atom, 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 each show a bonding position with another atom or another structure in the molecule of the third material.
