The present disclosure provides an azapyrene compound, a display panel and a display apparatus. The compound has a structure represented by Chemical Formula 1, in which X1-X4 are each a nitrogen atom or C—Ra, one or two of X1-X4 are a nitrogen atom; only one of X1 and X2 is a nitrogen atom; only one of X3 and X4 is N; Ra is mainly hydrogen, deuterium, or C1-C10 alkyl; Ar1 and Ar2 are each C6-C30 aryl or C3-C30 heteroaryl; m and n are 0, 1, 2, or 3, and when one of m and n is 0, the other one of m and n is not 0; and L1 and L2 are a single bond, C6-C30 arylene, or C3-C30 heteroarylene; p and q are 0, 1, or 2. The compound can be used as a CPL material to improve external quantum efficiency (EQE) of an organic light-emitting device and light-emitting efficiency.
