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.
