Abstract: The present disclosure relates to an organic light emitting diode in which an emitting material layer disposed between two electrodes includes a first compound in which an electron donor moiety is liked to an electron acceptor moiety via a carbon-carbon bond, and a second compound forming a fused ring between a boron atom and a nitrogen atom, and an organic light emitting device including the organic light emitting diode. The first compound and the second compound may be included in the same emitting material layer or adjacently disposed emitting material layers. The organic light emitting diode includes the emitting material layer where includes first compound that have high bonding energy between the electron acceptor moiety and the electron donor moiety, and a second compound with an adjusted energy level compared to an energy level of the first compound, so that driving voltages of the organic light emitting diode can be lowered and luminous efficiency and luminous lifetime of the organic light emitting diode can be improved.
