  • Patent number: 8167675
    Abstract: A dispersion-type EL element is a dispersion-type electroluminescent element with at least a transparent coating layer, a transparent conductive layer, a phosphor layer, a dielectric layer and a rear electrode layer sequentially formed on a base film surface. The transparent coating layer can be peeled off the surface of the base film. The transparent conductive layer is formed by applying a coating liquid composed mainly of conductive oxide particles and a binder on a surface of the transparent coating layer, applying compression processing to the applied layer and then curing the compressed layer.
    Type: Grant

  • Patent number: 8110986
    Abstract: A dispersion-type EL element formed on a thin or flexible transparent plastic film and a method for manufacturing the same are provided. The dispersion-type electroluminescent element is a dispersion-type electroluminescent element with at least a transparent conductive layer, a phosphor layer, a dielectric layer, and a rear electrode layer sequentially formed on a transparent plastic film surface, in which a thickness of the transparent plastic film is less than 50 ?m, and the transparent conductive layer is formed by applying compression processing to an applied layer formed by applying a transparent conductive layer forming application liquid mainly composed of conductive oxide particles and a binder on the transparent plastic film surface and then, curing the compressed layer.
