An object of the present invention is to provide an organic electroluminescent device having a hole blocking layer capable of lowering the driving voltage. The present invention relates to an organic electroluminescent device including an anode, a cathode, a first light emitting layer formed by a wet film forming method, and a second light emitting layer formed by a vacuum deposition method, wherein the first light emitting layer is a low molecular weight element. A phosphorescent light emitting material that is a compound and a first charge transporting material, wherein the second light emitting layer contains a fluorescent light emitting material and a second charge transporting material that are low molecular weight compounds, and the cathode of the second light emitting layer The hole blocking layer adjacent to the side relates to an organic electroluminescence device containing a specific compound. |
