Abstract

L'invention concerne un élément organique électroluminescent qui présente une grande luminance d'émission, une faible tension de commande et un faible taux d'occurrence de fuites. L'invention concerne spécifiquement un élément organique électroluminescent qui comprend au moins une électrode positive et une électrode négative sur un substrat support, tout en comprenant une couche électroluminescente qui est agencée entre l'électrode positive et l'électrode négative et contient au moins une substance organique. L'élément organique électroluminescent comprend également au moins une couche de transport d'électrons entre l'électrode négative et la couche électroluminescente. L'électrode négative est formée par application d'une solution qui contient de l'argent, et la couche de transport d'électrons est formée par un procédé qui comprend une étape d'application d'une solution qui contient un matériau de transport d'électrons représenté par la formule générale (1) et un métal ou un sel du métal. Le rapport massique entre le métal ou le sel du métal et le matériau de transport d'électrons représenté par la formule générale (1) est dans la plage allant de 0,5:1 à 99:1. Formule générale (1) : Ar1-(Ar2)n (Dans la formule, Ar1 représente un groupe dérivé d'un cycle hydrocarboné aromatique ou un groupe dérivé d'un cycle hétérocyclique aromatique ; Ar2 représente un groupe dérivé d'un cycle hétérocyclique aromatique ; et n représente un entier de 2 ou plus.)
