  • Patent number: 10901563
    Abstract: A touch panel sensor includes a substrate and an electrode having a detection electrode and an extraction electrode connected to a detection electrode. The electrode, in any cross-section thereof in the thickness direction, includes a metal layer which occupies at least part of the cross-section. The metal layer of the detection electrode and the metal layer of the extraction electrode are formed integrally at a joint between the detection electrode and the extraction electrode. The detection electrode includes a conductive mesh having conductive wire arranged in a mesh pattern, the conductive wire having a height of not less than 0.2 ?m and not more than 2 ?m and a width of not less than 1 ?m and not more than 5 ?m. The conductive wire of the conductive mesh each have a base surface on the substrate side, and a flat top surface located opposite to the base surface.

  • Patent number: 9678248
    Abstract: In order to improve the scratch resistance of an antireflective article having a moth-eye structure, an antireflective article is provided that has fine protrusions densely arranged therein, and has the interval between adjacent fine protrusions being no more than the shortest wavelength in the wavelength band for antireflection. At least some of the fine protrusions are fine protrusions having a plurality of apexes.
