Touch panel device and image display device including the touch panel device
A touch sensor panel includes a plurality of sensors. A protective plate protects the touch sensor panel. A transparent adhesive material attaches the touch sensor panel and the protective plate. A moisture-proof sealing member has water vapor permeability that is lower than water vapor permeability of the transparent adhesive material. A flexible wiring board connects the plurality of sensors to an external circuit. The transparent adhesive material has a region that is out of contact with the protective plate or the touch sensor panel, and at least a part of the region is covered by the moisture-proof sealing member.
