Abstract

Une OLED empilée comprend une première électrode, une deuxième électrode, une pluralité de régions luminescentes disposées entre les première et deuxième électrodes, et une électrode intermédiaire disposée entre des régions luminescentes successives. Au moins une électrode intermédiaire comprend une couche métallique-organique mixte disposée entre une première couche d'injection de charge et une deuxième couche d'injection de charge.
