Abstract: The present disclosure relates to an organic light-emitting diode exhibiting high luminance efficiency, low-voltage operation, and long lifespan and, more particularly, to an organic light-emitting diode, comprising: a first electrode; a second electrode facing the first electrode; and a light-emitting layer and an electron density control layer sequentially arranged between the first electrode and the second electrode wherein the light-emitting layer includes at least one of the amine compounds represented by Chemical Formula A or B and the electron density control layer includes at least one of the compounds represented by Chemical Formulas F to H. The structures of Chemical Formulas A, B, and F to H are as described in the specification.
