- X1 to X4 are the same as or different from each other, and each independently N, CH, CRa, or C linked to L1, two or more of X1 to X4 are N, and any one of X1 to X4 is C linked to L1,
- X5 to X8 are the same as or different from each other, and each independently N, CH or CRa,
- at least one of X1 to X8 is CRa,
- Ra is a substituted or unsubstituted aryl group having 6 to 60 carbon atoms;
- or a substituted or unsubstituted heterocyclic group having 2 to 60 carbon atoms,
- L1 is a direct bond;
