  • Patent number: 9332633
    Abstract: There is provided a transparent conductive film which comprises: a film substrate; a plurality of transparent conductor patterns formed on the film substrate; and a pressure-sensitive adhesive layer wherein the transparent conductor patterns are embedded. The plurality of transparent conductor patterns respectively have a two-layer structure wherein a first indium tin oxide layer and a second indium tin oxide layer are laminated on the film substrate in this order, and the first indium tin oxide layer has a greater tin oxide content than the second indium tin oxide layer does. The first indium tin oxide layer has a smaller thickness than the second indium tin oxide layer does.

  • Patent number: 9223165
    Abstract: Provided is an optical unit for a display panel device with a capacitive touch input function. In the optical unit, a touch panel laminate comprises: an optically transparent first substrate layer laminated to one surface of a transparent adhesive layer; a first transparent electrically conductive layer laminated, through a first undercoat layer, to a surface of the first substrate layer on a side opposite to the adhesive layer; an optically transparent second substrate layer laminated to the other surface of the adhesive layer; and a second transparent electrically conductive layer laminated, through a second undercoat layer, to a surface of the second substrate layer on a side opposite side to the adhesive layer.

  • Publication number: 20130288047
    Abstract: Disclosed is a highly productive method for manufacturing a transparent conductive film. The method includes the step of sputter depositing a transparent, amorphous tin-indium oxide conductive layer on a transparent substrate. The surface of the substrate, on which the transparent conductive layer is formed, has an arithmetic mean roughness Ra of 1.0 or less. The sputter depositing step is performed under an atmosphere having a water partial pressure of 0.1% or less based on an AR gas partial pressure at a base material temperature of more than 100° C. and 200° C. or less, using a metal target or oxide target in which the amount of tin atoms is more than 6% by weight and 15% by weight or less, based on the total weight of indium and tin atoms.
