Abstract
Disclosed herein is an organic light-emitting diode, comprising: a first electrode, a second electrode opposite the first electrode, and a light-emitting layer and an electron-density-controlling layer in that order between the first electrode and the second electrode, wherein the electron-density-controlling layer includes at least one selected from among compounds represented by Chemical Formulas A to D, and the light-emitting layer includes at least one anthracene compound represented by Chemical Formula H. The electron-density-controlling layer may be disposed between the light-emitting layer and an electron transport layer.
