Patent ID: 7898169

Claim:
An organic electro-luminescence display device comprising: a first electrode on a substrate, the first electrode being independently patterned; a subpixel separating pattern on portions of the substrate that correspond to an edge and a periphery of the first electrode; a first charge transport pattern on the first electrode, the first charge transport pattern including an first insoluble material, a first charge transport materials forming the first charge transport pattern; an organic emission pattern on the first charge transport pattern; a second charge transport pattern on the organic emission pattern, the second charge transport pattern including an second insoluble material, a second charge transport materials forming the second charge transport pattern; and a second electrode on the second charge transport pattern, wherein the first insoluble material comprises at least one material selected from the group consisting of aziridine, carbodiimide, oxilan, alcohol, glycidyl ether, glycidyl ester, a carboxyl compound, amine, epoxide, vinyl sulfone, amide, an aryl compound, and a silane-based coupling agent, wherein the first charge transport material comprises at least one material selected from the group consisting of an arylene diamine derivative, a biphenyl derivative having a starburst type compound and a spero group, N,N-diphenyl-N,N′-bis(4-methyl phenyl)-1,1′-biphenyl-4,4′-diamine (TPD), 4,4′-bis[N-(1-naphthy)-N-phenyl amino]biphenyl (NPB), TiO 2 , ZnO 2 , and SnO 2 , wherein the second insoluble material comprises a silane coupling agent, and wherein the second charge transport material comprises at least one material selected from the group consisting of poly{[9,9-bis(6′(N,N,N-tri-methyl ammonium) hexyl-fullerene-2,7-diyl)-alt-[2,5-bis(p-phenylene-1,3,4-oxadiazoles)](PFON + (CH 3 ) 3 I − -PBD), 8-hydroxyquinolino-aluminum (Alq3), Benzoquinolinol complex (Bebq2), triazole derivative (TAZ), and phenanthroline derivative (MEPHPH), LiCF 3 SO 3 , LiClO 4 , LiBF 4 , LiPF 6 , and LiN(CF 3 SO 2 ) 2 .
