The device includes an anode, a light-emitting layer, a cation-containing water-soluble polymer layer and a cathode formed in this order on a substrate wherein the cation-containing water-soluble polymer layer is formed by wet coating. The cation-containing water-soluble polymer layer as a secondary thin film layer is not dissolved in a solvent for the formation of the underlying light-emitting layer to prevent intermixing between the two layers, thereby enabling the formation of a multilayer structure by wet coating. In addition, the cation-containing water-soluble polymer layer attracts electrons injection from the cathode by an attractive Coulomb force to effectively increase the mobility of the electrons while blocking high-mobility holes from the anode at an interface between the light-emitting layer and the water-soluble layer. Further provided is a method for fabricating the electroluminescent device.

  • Patent number: 8222635
    Abstract: An electronic device includes at least a substrate, an area on the substrate which has to be protected against moisture and/or oxygen, at least one contact, and an encapsulation layer system including at least a first inorganic layer. The at least one contact extends from the sealed area to a part of the substrate not sealed by the encapsulation layer system. The contact includes a shunt, which is an interruption bridged by an electrically conductive bridge. The first inorganic layer of the encapsulation system is applied so that it is in direct physical contact with the electrically conductive bridge. The bridge has a structure and shape which can be sealingly covered by the encapsulation layer system and is made from a material through which no moisture and/or oxygen can penetrate.
