  • Patent number: 9811221
    Abstract: An input device having a row electrode and a column electrode made by patterning a meshed metallic layer by forming a dividing section on a metallic line constituting the meshed metallic layer can suppress variability in areas of individual dividing sections formed on the metallic lines, whereby uneven shading due to the patterned, meshed conductive layer is suppressed from appearing on a touch operation surface. In the input device having the row electrode and the column electrode made by patterning the meshed metallic layer by forming the dividing section on the metallic line constituting the meshed metallic layer, a mesh side section intersecting with an ideal contour Sp2 of the column electrode (meshed electrode) corresponding to one side of a mesh in the metallic line Mw2 is divided by a dividing section Rs that does not overlap with an intersection Mcp of the metallic lines to form an actual contour of the column electrode.
