Abstract: The present disclosure relates to an organic compound having a binaphthyl core and a group connected to the biphenyl core and having excellent charge mobility property, and a light emitting diode and a light emitting device having the organic compound. The organic compound can be applied into the light emitting diode by using solution process and has very deep HOMO energy level. When the organic compound is applied into a chare transfer layer, a HOMO energy level bandgap between the charge transfer layer and an emitting material layer is reduced so that holes and electrons can be injected into the emitting material layer in a balanced manner.
