Abstract

Embodiments relate to a delayed fluorescence compound and a display device including the delayed fluorescence compound. The delayed fluorescence compound includes an electron acceptor moiety of benzo[4,5]thieno[2,3- b ]quinoxaline and at least one electron donor moiety covalently bonded to the electron acceptor moiety. The at least one electron donor moiety is covalently bonded to a benzene ring of benzo[4,5]thieno[2,3- b ]quinoxaline and is selected from carbazole, phenylcarbazole, acridine, and phenylacridine. The effective charge transfer in the delayed fluorescence compound results in improved emitting efficiency of the compound.
