  • Publication number: 20170005288
    Abstract: The present invention pertains to a process for the manufacture of a display device, said process comprising the following steps: (1) providing a front-sheet electrode, (2) providing a back-sheet electrode, and (3) interposing between the front-sheet electrode and the back-sheet electrode one or more layers consisting of at least one organic semiconductor material, wherein said front-sheet electrode is an assembly comprising one or more multilayer assemblies obtainable by: (i) providing at least one layer (L1) consisting of a composition [composition (C1)] comprising, preferably consisting of at least one thermoplastic polymer [polymer (T1)], said layer (L1) having two opposite surfaces; (ii) treating at least one surface of the layer (L1) with a radio-frequency glow discharge process in the presence of an etching gas medium; (iii) applying by electroless deposition a layer consisting of at least one metal compound (M1) [Layer (L2)] onto each treated surface of the layer (L1) provided in step (ii).
