Abstract: An organic compound having a spiro-anthracene core and an aromatic or heteroaromatic group and/or an amino group bonded to the core, and an organic light-emitting diode and an organic light-emitting device including the organic compound are disclosed. Since the organic compound of the present disclosure has a rigid structure and a substantially narrow full width at half maximum (FWHM), it is possible to manufacture an organic light-emitting diode and an organic light-emitting device with lowered driving voltages and enhanced luminous efficiency and color purity using the organic compound.

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.
