Abstract: A method of manufacturing an organic light emitting device includes providing a substrate and forming an anode on the substrate; melting at least two organic materials having different melting points by a heating means; and coating and cooling each of the melted at least two organic materials on a surface of the anode respectively, in sequence, to form an organic compound layer having at least active layer. A melting point of one of the at least two active layers adjacent to the anode is greater than a melting point of another of the at least two active layers away from the anode.
