  • Patent number: 7148439
    Abstract: The present invention provides a touch panel having: a first panel board having a first base layer and a first conductive thin film disposed on one side of the first base layer; and a second panel board having a second base layer and a second conductive thin film disposed on one side of the second base layer; wherein the first panel board and the second panel board are arranged thorough a spacer so that the first conductive thin film and the second conductive thin film face each other, wherein the distance between the first conductive thin film and the second conductive thin film is from 20 to 100 ?m, wherein the touch panel has a pushing angle of 3.9° or less at a point distant from an electrode provided at an end portion of the first panel board by 1.5 mm.

  • Publication number: 20050129877
    Abstract: A resin sheet that is unlikely to be affected by heat and allows prevention of the occurrence of a crack is provided. A glass fiber cloth-like material is dipped into an epoxy resin solution and subjected to curing, thereby obtaining an epoxy resin-based sheet including the glass fiber cloth-like material. The resin sheet has a haze value of 10% or lower, and preferably, has a light transmittance of 88% or higher, an in-plane retardation of not more than 2 nm, a retardation in a thickness direction of 40 nm, and a surface roughness of not more than 2 ?m.

  • Publication number: 20050045471
    Abstract: A process for producing a transparent conductive laminate having a completely crystallized, transparent conductive layer on a substrate comprising an organic polymer molding is provided. The transparent conductive layer is excellent in transparency and wet heat confidence, is not excessively low in specific resistivity, and has no variation on optical properties such as retardation characteristic. The transparent conductive laminate is obtained by sputter-film forming a transparent conductive layer on a substrate comprising an organic polymer molding under conditions of a substrate temperature of 80-150° C. and a degree of vacuum of 8×10?3 Pa or lower to form an amorphous transparent conductive layer comprising an In.
