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: At least one emitting material layer in an organic light emitting diode (OLED) includes a first compound of phosphorescent material having the following structure of Chemical Formula 1, Ir(LA)m(LB)n, a second compound of a P-type host, and optionally a third compound of an N-type host. The luminous efficiency, color purity and luminous lifespan of the OLED and the organic light emitting device can be improved.
