the substituted or unsubstituted aryl group of the one of Ar1 and Ar2 is a substituted or unsubstituted aryl group having 7 to 30 ring carbon atoms,

wherein in Formula 4, a is an integer of 1 to 3,
wherein in Formula 6,
i) Ar1 and Ar2 are not dimethylfluorenyl groups,
ii) when any one of Ar1 and Ar2 is a p-biphenyl group and the other one of Ar1 and Ar2 includes an aryl substituent, the number of ring carbon atoms in the aryl substituent is 13 to 30,
iii) L is a phenylene group, a is an integer of 1 or more and 3 or less, and when L includes an m-phenylene group, Ar1 and Ar2 are not an unsubstituted or alkyl-substituted phenyl group, or an unsubstituted p-biphenyl group, and
vi) when Ar1 and Ar2 are each a heteroaryl group comprising S, or one of Ar1 or Ar2 is a heteroaryl group comprising S, and an other one of Ar1 or Ar2 is a heteroaryl group comprising O, the heteroaryl group comprising S is a substituted or unsubstituted dibenzothiophene group, and the heteroaryl group comprising O is a substituted or unsubstituted dibenzofuran group, and
wherein in Formula 7 and Formula 8,
i) Ar1 and Ar2 are not an unsubstituted p-biphenyl group or an unsubstituted p-terphenyl group,
ii) when Ar1 and Ar2 are a fluorene group or a fluorene derivative, Ar1 and Ar2 are substituents represented by Formula 7a;, wherein in Formula 7a,
R3 is a hydrogen atom, a deuterium atom, a halogen atom, 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, or a substituted or unsubstituted aryl group having 6 to 30 ring carbon atoms,
R4 and R5 are each independently a hydrogen atom, a deuterium atom, a halogen atom, a substituted or unsubstituted cycloalkyl group having 3 to 20 ring carbon atoms, or a substituted or unsubstituted aryl group having 6 to 30 ring carbon atoms, or may combine with each other to form a ring,
is an integer of 0 or more and 3 or less,
p is an integer of 0 or more and 4 or less,
iii) L is a substituted or unsubstituted phenylene group, and
vi) when one of Ar1 and Ar2 is an unsubstituted 2-dibenzofuran group, an unsubstituted 2-dibenzothiophene group, an unsubstituted 3-dibenzofuran group, or an unsubstituted 3-dibenzothiophene group, the other one of Ar1 and Ar2 is a substituted or unsubstituted phenylnaphthyl group, a substituted or unsubstituted dibenzofuran group, or a substituted or unsubstituted dibenzothiophene group.
