Abstract

Provided are a boron-silicon heterocyclic compound having a structure represented by formula 1, a display device and a display apparatus. In formula 1, Land Lare each a single bond, C6-C30 arylene, C6-C30 fused arylene, C4-C30 heteroarylene, or C4-C30 fused heteroarylene; Dand Dare each a substituted or unsubstituted C6-C60 aryl, a substituted or unsubstituted C4-C60 heteroaryl, a substituted or unsubstituted C10-C60 fused aryl, a substituted or unsubstituted C8-C30 fused heteroaryl, or a substituted or unsubstituted diphenylamino. The compound has a strong inductive effect and can reduce the driving voltage of the device. The silacyclopentadiene having a silicon atom as spiro-atom can effectively improve the solubility of the material, which is beneficial to the cleaning of the vapor deposition mask. In addition, the compound has a higher triplet energy level to effectively transfer energy to the luminous body, and improves the efficiency of the device.
