In general, organic light emitting phenomenon refers to a phenomenon of converting electrical energy into light energy using an organic material. An organic light emitting device using an organic light emitting phenomenon usually has a structure including an anode and a cathode and an organic material layer therebetween. In this case, the organic material layer is often formed of a multi-layered structure composed of different materials to increase the efficiency and stability of the organic light emitting device, for example, it may be made of a hole injection layer, a hole transport layer, a light emitting layer, an electron transport layer and an electron injection layer.
