  • Publication number: 20190050098
    Abstract: A sensor base material and a photic base material such as a polarizing plate are stacked together. An opening is formed in the photic base material. Although the joining part of a flexible wiring board is joined to the sensor base material, a large portion of an opposing edge facing a display and input region, the opposing edge being part of the joining part, is positioned in the opening, so bubbles along the opposing edge are less likely to be generated, making the display quality of the display and input region less likely to be affected. In addition, since the both-side substrate ends of the joining part are sandwiched between the sensor base material and the photic base material, the joining part is less likely to be deformed, making it easy to prevent damage to the sensor base material.

  • Publication number: 20180224975
    Abstract: A capacitive sensor having a bending portion and a flat portion and bendable in the bending portion includes a plurality of first transparent electrodes, a plurality of second transparent electrodes, a coupling member, and a bridge wiring member. The first transparent electrodes are arranged in a first direction. The second transparent electrodes are arranged in a second direction crossing the first direction. The coupling member is provided integrally with either the first transparent electrodes or the second transparent electrodes. The bridge wiring member is provided separately from the first transparent electrodes or the second transparent electrodes, to which the coupling member is not provided, in a portion where the bridge wiring member crosses the coupling member. A direction in which the coupling member extends in the bending portion is different from a direction in which the coupling member extends in the flat portion.
