Abstract

Un dispositif d'affichage comprend une anode (22), une cathode (28) et une région luminescente (26) disposée entre l'anode (22) et la cathode (28).L'anode (22) comprend une couche de mélange métallique-organique (24) combinée de manière fonctionnelle avec une matière réceptrice d'électrons. Une anode (22) peut comprendre un mélange d'une couche de mélange métallique-organique (24) et d'une matière réceptrice d'électrons dans une seule couche de l'anode (22). En variante, l'anode (22) peut avoir une configuration à couches multiples, comprenant une couche de mélange métallique-organique (24) et une couche tampon (25) adjacente à la couche de mélange métallique-organique.Application aux dispositifs d'affichage électroluminescents organique (OLED).
