  • Patent number: 9607733
    Abstract: A double-sided transparent conductive film including a base material film, having an anti-blocking layer, an optical adjusting layer and a transparent conductive layer formed in this order on each of both sides of the base material film, wherein an anti-blocking layer containing particles is formed at least one of: a location between the base material film and one optical adjusting layer; and a location between the base material film and the other optical adjusting layer, the anti-blocking layer has a flat portion and protrusion portions caused by the particles, and a value obtained by subtracting a thickness of the flat portion of the anti-blocking layer from a mode diameter of the particles is larger than a thickness of the optical adjusting layer.

  • Patent number: 9609745
    Abstract: A transparent conductive film includes a film base, a cured resin layer formed at one side of the film base, and an indium composite oxide layer laminated at a side of the cured resin layer opposite to the film base. The indium composite oxide layer has a thickness of 20 nm to 50 nm. The cured resin layer has a plurality of spherical particles and a binder resin layer which fixes the plurality of spherical particles to the film base. A difference w?d between a mode particle size w and a thickness d of the binder resin layer is greater than zero and less than or equal to 1.2 ?m, where w is a mode particle size of the spherical particles and d is a thickness of the binder resin layer.

  • Patent number: 8853556
    Abstract: A transparent conductive film which comprises: a substrate composed of a non-crystalline polymer film; a first hard coating layer; a first transparent conductor layer; a first metal layer; a second hard coating layer; a second transparent conductor layer; and a second metal layer. The first hard coating layer includes a binder resin and a plurality of sphere-shaped particles having a diameter of 1 ?m to 5 ?m. The first metal layer has a plurality of projections having a maximum height Rz of 0.5 ?m to 2.5 ?m resulting from the plurality of particles included in the first hard coating layer on a surface thereof.

  • Publication number: 20140106131
    Abstract: A transparent conductive film for a display element which includes a black matrix having a polygonal opening and has a definition of 150 ppi or more, the transparent conductive film including: a transparent polymer base material; a transparent conductive layer; and a cured resin layer, wherein an outermost surface layer on a side where the cured resin layer is formed has a flat portion and a protrusion portion on the surface, a height of the protrusion portion is larger than 10 nm above the flat portion, and a maximum diameter of a cross-sectional shape formed by intersection of a surface parallel to the flat portion and the protrusion portion at a distance of 10 nm from the flat portion is smaller than a minimum value of distances between two non-adjacent sides of the opening of the black matrix.
