The object of the invention is to provide an organic electroluminescent element comprising a hole blocking layer capable of achieving a lower driving voltage. The invention relates to an organic electroluminescent element comprising: an anode, a cathode, a first luminescent layer formed by a wet film forming method, and a second luminescent layer formed by a vacuum evaporation method, wherein the first luminescent layer contains a phosphorescent material of a low-molecular-weight compound and a first charge transporting material, and the second luminescent layer contains a fluorescent material of a low-molecular-weight compound and a second charge transporting material, and the hole blocking layer, which is adjacent to the cathode side of the second luminescent layer, contains a specific compound. |
