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.
