Abstract: The present disclosure relates to an organic compound having the following structure, and an organic light emitting diode (OLED) and an organic light emitting device including the organic compound. The organic compound can be a bipolar compound having a p-type moiety and an n-type moiety and has high energy level and proper energy bandgap for an emissive layer of the OLED. As the organic compound is applied into the emissive layer, the OLED can maximize its luminous properties as holes and electrons are recombined uniformly over the whole area in an emitting material layer (EML).

Abstract: An organic light emitting diode includes a first electrode; a second electrode facing the first electrode; and an organic emitting layer between the first and second electrodes. The organic emitting layer includes a first emitting part between the first and second electrodes, a second emitting part between the first emitting part and the second electrode, and a charge generation layer between the first emitting part and the second emitting part. The charge generation layer includes an n-type charge generation layer between the first emitting part and the second emitting part, and a p-type charge generation layer between the n-type charge generation layer and the second emitting part. The p-type charge generation layer has a multi-layered structure, where an organic charge generation material layer and an inorganic charge generation material layer are alternately stacked.
