Abstract

Discussed is an organic compound having a benzofluorenocarbazole core and an aromatic or hetero aromatic groups bonded to a specific positions of the benzofluorenocarbazole core, and an organic light emitting diode and an organic light emitting device including the compound. The organic compound has a narrow Stokes Shift between an absorption spectrum peak and an emission spectrum peak, it has a broad spectral overlapping area between its absorption wavelength range and an emission wavelength range of another luminous material. Therefore, it can emit light having high color purity and exhibit excellent luminous efficiency.
