    摘要： The present invention relates to a highly efficient organic electroluminescent device, and particularly to an organic electroluminescent device comprising an anode (a first electrode), a cathode (a second electrode), and one or more organic luminescent layers formed between the anode and the cathode, having an emission layer, wherein the emission layer comprises a doping region having host material and doping material, and a non-doping region having only host material as the hole blocking layer, which is in contact with the doping region, and a preparation method thereof. The organic electroluminescent device of the present invention is characterized in high efficiency, low cost, and improved process without forming the hole blocking layer by using a separate organic material.
