X 3 is —N— or —CR 3 —,
X 4 is —N— or —CR 4 —,
R 1 to R 4 are each independently hydrogen, deuterium, a substituted or unsubstituted C1 to C20 alkyl group, a substituted or unsubstituted C6 to C30 aryl group, a substituted or unsubstituted C3 to C30 heteroaryl group, or a combination thereof, and
Ar 1 includes a benzimidazole group or a benzoxazole group, and
L 1 is a substituted or unsubstituted C2 to C6 alkenylene group, a substituted or unsubstituted C2 to C6 alkynylene group, a substituted or unsubstituted C6 to C30 arylene group, a substituted or unsubstituted C3 to C30 heteroarylene group, or a combination thereof,
n is an integer from 0 to 2, and
X 6 to X 8 are each independently —N— or —CR′—,
R′ is hydrogen or deuterium,
at least one of X 6 to X 8 is —N—, and
R 5 and R 6 are each independently a substituted or unsubstituted phenyl group, a substituted or unsubstituted naphthyl group, a substituted or unsubstituted anthracenyl group, a substituted or unsubstituted phenanthrenyl group, a substituted or unsubstituted triphenylenyl group, a substituted or unsubstituted pyrenyl group, a substituted or unsubstituted chrysenyl group, or a combination thereof.

2. The compound as claimed in claim 1 , wherein:
n is an integer from 1 to 2, and
L 1 is a substituted or unsubstituted ethenylene, a substituted or unsubstituted ethynylene, a substituted or unsubstituted phenylene, a substituted or unsubstituted biphenylene, a substituted or unsubstituted naphthalene, a substituted or unsubstituted pyridinylene, a substituted or unsubstituted pyrimidinylene, or a substituted or unsubstituted triazinylene.
