Abstract
To provide an organic electroluminescent element that can attain efficiency improvement by forming an electron injection layer by a film that is stable and excellent in uniformity, and forming a charge generation layer capable of effectively exhibiting the function. In an organic electroluminescent element provided with at least one organic layer between a pair of electrodes, an electron injection layer comprising a ZnO-containing layer, and a charge generation layer containing an electron acceptor-containing film in contact with the cathode side thereof and an electron donor-containing film adjacent thereto are formed.
