Abstract: PURPOSE: An organic light emitting diode and a manufacturing method thereof are provided to implant an inorganic nano particle between a first electrode and an electron transporting layer, thereby lowering the driving voltage of a device. CONSTITUTION: An inverted organic light emitting diode is made of a substrate, a cathode, an electron implanting or electron transporting layer(13), a light emitting layer(14), a hole transporting or hole implanting layer(16), and an anode. The electron implanting or electron transporting layer is made of inorganic nano particles. The cathode is made of thin metal films. The hole transporting or hole implanting layer is made or an organic layer, a material in which p type material is doped in an organic layer, or inorganic nano particles. The anode is made of metal whose diameter is longer than 60nm.
