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.

Abstract: An organic light emitting diode including a plurality delayed fluorescent materials with specific energy levels and an organic light emitting device including the diode is disclosed. When the plurality delayed fluorescent materials with specific energy levels are applied in an emitting material layer, it is possible to minimize the energy loss or exciton quenching during luminous process and to prevent the diode from reducing life span caused by the exciton quenching. When the emitting material layer includes other luminous material having a narrow FWHM, the organic light emitting diode can enhance its color purity.
