Abstract: An organic light emitting device is provided to reduce hole injection barrier by forming a surface dipole between a first electrode and a hole implant layer. A first electrode(120) is formed on a substrate(110), and a second electrode(130) is formed on the first electrode. An intermediate layer(140) between the second electrode and the first electrode comprise an organic light-emitting layer and a hole implant layer, and a hole implant layer contains the copper iodide while contacting with the first electrode.
