Abstract
Disclosed is an organic light emitting diode, including a cathode electrode and an anode electrode positioned above the cathode electrode. An emitting layer is positioned between the cathode electrode and the anode electrode. An electron transporting unit is positioned between the cathode electrode and the emitting layer. The electron transporting unit is configured to inject and transport electrons to the emitting layer. A buffer layer is disposed between the cathode electrode and the electron transporting unit. The buffer layer includes an organic layer and a metallic layer disposed on the organic layer.
