  • Patent number: 11397498
    Abstract: A method for manufacturing an electrode film includes the steps of laminating a metal layer and a black photoresist layer sequentially on a first main surface of a transparent base material, subjecting the black photoresist layer to patterning in a mesh shape by partially exposing the black photoresist layer and performing development, processing the metal layer into a metal mesh electrode by subjecting the metal layer to etching by using the black photoresist layer subjected to the patterning as an etching mask until the metal layer has a width smaller than a width of a thin wire line constituting a mesh of the black photoresist layer, and covering an upper surface and both side surfaces of a thin wire line constituting a mesh of the metal mesh electrode with the black photoresist layer by heating and softening the black photoresist layer to cause the black photoresist layer softened to flow.

  • Patent number: 9152289
    Abstract: An installation structure of electronic paper and a resistive film type touch panel, includes electronic paper, a resistive film type touch panel disposed on a back surface side of the electronic paper, and a multitude of protrusions that are disposed between the electronic paper and the resistive film type touch panel, and that are fixed to at least one of the electronic paper and the resistive film type touch panel.

  • Publication number: 20100013786
    Abstract: A protective panel with a touch input function for an electronic apparatus display window is adapted to be fitted into a panel fitting section of a casing having an opening without a gap so as to be held therein such that the outside surface thereof forms the same plane, with a display disposed the panel below being protected in such a manner as to be visually recognized from the outside through a transparent window portion, wherein a fine concave/convex portion is partly formed on the surface of a hard coat layer.
