ORGANIC ELECTROLUMINESCENT ELEMENT AND METHOD FOR MANUFACTURING SAME

WIPO Patent Application WO/2013/157451

A1

To provide: (1) an organic-inorganic hybrid-type organic electroluminescent element having excellent light-emission characteristics in which even when a low-molecular compound layer is used as the layer constituting the organic electroluminescent element, crystallization of the low-molecular compounds is suppressed; (2) an organic-inorganic hybrid-type organic electroluminescent element having even better light-emission characteristics than conventional organic-inorganic hybrid-type organic electroluminescent elements; and (3) an organic electroluminescent element that is easy to manufacture and that has excellent light-emission efficiency and lifespan. The present invention is an organic electroluminescent element having a structure in which a plurality of layers are stacked, the organic electroluminescent element being characterized in having a metal oxide layer between a first electrode and a second electrode and having, on the metal oxide layer, a buffer layer formed from an organic compound.
