ELECTROLUMINESCENT DISPLAY

Abstract

Electroluminescent display comprising: a substrate (110); an anode electrode (ANO) on the substrate (110); an emission layer (EL) on the anode electrode (ANO); and a cathode electrode (CAT) on the emission layer (EL), wherein the cathode electrode (CAT) has several conductive layers (CAT1, CAT2, CAT3, CAT4, CAT5) stacked on top of each other, wherein: the several conductive layers (CAT1, CAT2, CAT3, CAT4, CAT5) comprise a metal layer (20) and a metal oxide layer (10) stacked on top of each other, and a resin layer on the metal oxide layer (10) or the metal layer (20), wherein the resin layer contains a conductive resin material;or the multiple conductive layers (CAT1, CAT2, CAT3, CAT4, CAT5) comprising a first conductive layer (CAT1) in contact with the emission layer (EL), a second conductive layer (CAT2) in contact with the first conductive layer (CAT1), and a third conductive layer (CAT3) in contact with the second conductive layer (CAT2), wherein the second conductive layer (CAT2) contains a conductive resin material, wherein the conductive resin material comprises: a domain material with at least one of Tris(8-hydroxyquinoline)aluminium, 1,3,5-Tri(m-pyrid-3-yl-phenyl)benzene, bathophenanthroline, 1,2,3-triazole and triphenyl bismuth; and a dopant dispersed in the domain material, wherein the dopant comprises an alkali metal material comprising at least one of lithium, cesium, cesium oxide, cesium nitride or rubidium, or the dopant comprises buckminsterfullerene.;
