  • Patent number: 7833607
    Abstract: A multilayer film includes a substrate film (a), a hard coat layer (b) containing a (meth)acrylate compound, an electrically conductive layer (c) containing electrically conductive particles, and a resin layer (d) containing a fluorine compound, those layers being disposed on at least one face of the substrate film (a). The resin layer (d) has fine irregularities on the surface and an arithmetic average surface roughness Ra ranging from 0.003 ?m to 0.025 ?m and the surface of the resin layer (d) of the multilayer film has a reflectance of less than 2%. The display filter and the display each include the multilayer film.

  • Publication number: 20100196655
    Abstract: A display-use filter, which comprises a laminated body comprising a transparent substrate, light-shielding convex portions formed on the transparent substrate, a resin layer stacked on the light-shielding convex portions and a non-convex area existing between the light-shielding convex portions, wherein a concave section of the resin layer is formed in the non-convex area, and the resin layer has a center-line average roughness Ra in a range from 50 to 500 nm.

  • Publication number: 20060029749
    Abstract: A display panel wherein an electroconductive polymer layer is arranged between a display unit and a light source of a back light system. The electroconductive polymer layer makes it possible to make coloration or light scattering less than ITO or the like, and further prevent or decrease picture disturbances, such as flickering and stripe drifting, generated remarkably in high resolution pictures such as high-vision pictures, high speed movies, and displays corresponding to large screens by the action of electric waves radiated from the back light system, as noises, onto an operation circuit for the display.

  • Publication number: 20050221054
    Abstract: The present invention provides a multilayer film that is among antireflective films including low-refractive index thin-films and high-refractive index thin-films, a display filter including the multilayer film, and a display including the multilayer film. The multilayer film has enhanced surface hardness, improved scratch resistance, low reflectance, and high transparency and functions as a suitable antireflective film. The multilayer film includes a substrate film (a), a hard coat layer (b) containing a (meth)acrylate compound, an electrically conductive layer (c) containing electrically conductive particles, and a resin layer (d) containing a fluorine compound, those layers being disposed on at least one face of the substrate film (a). The resin layer (d) has fine irregularities on the surface and an arithmetic average surface roughness Ra ranging from 0.003 ?m to 0.025 ?m and the surface of the resin layer (d) of the multilayer film has a reflectance of less than 2%.
