Abstract:
1. A touch panel, comprising: an upper transparent electrode base member that has an upper transparent electrode disposed on one surface of the upper transparent electrode base member; a lower transparent electrode base member that has a lower transparent electrode disposed on a surface of the lower transparent electrode base member facing the surface of the upper transparent electrode base member on which the upper transparent electrode is disposed; and an insulating transparent adhesive layer that is disposed between the upper transparent electrode and the lower transparent electrode, the insulating transparent adhesive layer including a plurality of pressure-sensitive particles dispersed therein, wherein when a force acts upon another surface of the upper transparent electrode base member, the acting force causes a current to flow among the pressure-sensitive particles in the insulating transparent adhesive layer, whereby an electrical conduction is established between the upper transparent electrode and the lower transparent electrode, and positional coordinates where the force acted upon along the other surface of the upper transparent electrode base member are detected, and wherein the touch panel further comprises a transparent liquid-state intermediate layer disposed between the upper transparent electrode and the insulating transparent adhesive layer.
