要約
(EN) The present invention provides an organic electroluminescence device having excellent luminous efficiency and excellent luminance. The present invention relates to an organic electroluminescence device including a structure in which a plurality of layers is laminated between an anode and a cathode formed on a substrate; wherein the organic electroluminescence device includes a metal oxide layer between the anode and the cathode; and a nitrogen-containing film layer having an average thickness of not less than 0.1 nm but less than 3 nm adjacent to the metal oxide layer and disposed on an anode side.
(FR) L'invention porte sur un élément électroluminescent organique qui a une excellente efficacité lumineuse et une excellente luminance. La présente invention concerne un élément électroluminescent organique qui a une structure dans laquelle une pluralité de couches sont stratifiées entre une électrode positive et une électrode négative qui est formée sur un substrat, et qui comprend une couche d'oxyde métallique entre l'électrode positive et l'électrode négative, tout en ayant une couche qui est adjacente à la couche d'oxyde métallique sur le côté électrode positive, ladite couche étant formée d'un film contenant de l'azote et ayant une épaisseur moyenne d'au minimum 0,1 nm mais inférieure à 3 nm.
