    摘要： The present disclosure relates to an organic light emitting diode in which an emitting material layer disposed between two electrodes includes a first compound forming a fused ring among a boron atom and at least one of oxygen atom, sulfur atom and a selenium atom, 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 and second compounds with adjusting their energy levels 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.
