  • Patent number: 11284520
    Abstract: An input device includes a sensor unit, an optical layer superimposed on the sensor unit, and a flexible wiring substrate having a connection region held between the optical layer and support base member. The flexible wiring substrate has a flexible base member on which an electrode layer is provided and a wiring end that is an end of the electrode layer and is conductive with the terminal part with a conductive joining member. The wiring end is set back from an end of the flexible base member, so that the flexible base member has a protruding part protruding toward the sensing region. Since the input device has, on the sensing region side relative to a front end of the protruding part, a part into which the conductive joining member does not stick out, an air bubble region between the sensor unit and the optical layer can be narrowed.

  • Patent number: 10809832
    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.
