The present disclosure provides a boron-heterocyclic compound having a structure represented by Chemical Formula 1, in which L.sub.1 and L.sub.2 are each independently selected from a single bond, C6-C30 aryl, C6-C30 fused aryl, C4-C30 heteroaryl, or C4-C30 fused heteroaryl; and R.sub.1 and R.sub.2 are each independently selected from carbazolyl and derivative groups thereof, acridinyl and derivative groups thereof, and diarylamino and derivative groups thereof. In an embodiment, the boron-heterocyclic structure is suitable for use not only as an electron acceptor group but also as a linking group. By linking a group having a large steric hindrance to the boron atom of the boron-heterocyclic ring, the compound molecules are prevented or limited from aggregating, and thus a π-aggregation or excimer formed by direct accumulation of conjugate planes is avoided or reduced, thereby improving luminous efficiency. The present disclosure further provides a display panel and a display apparatus containing the compound. ##STR00001##
