Light-emitting layer material, light-emitting device, and display panel

Abstract

The present disclosure relates to the field of display technology, and in particular, to a light-emitting layer material, a light-emitting device, and a display panel, for improving the efficiency of light-emitting devices. The light-emitting layer material is selected from any one of the structures of the following general formula (I). A1, A2, and A3 are identical or different, and are each independently selected from any one of a substituted or unsubstituted C6-C30 aromatic ring and a substituted or unsubstituted C2-C30 heteroaromatic ring. X1, X2, X3, and X4 are identical or different, and are each independently selected from any one of a direct bond, O, S, NRA, CRBRC, and SiRDRE. RA, RB, RC, RD, and RE are identical or different, and are each independently selected from any one of the structures of general formula (IA). The light-emitting layer material described above is used for the light-emitting layer of light-emitting devices.
