Capacitance touch panel
Abstract:
A capacitance touch panel of the invention includes a display, a lower adhesive layer, a capacitance touch panel sensor, an upper adhesive layer and a protective substrate, which are formed in this order. Relative permittivity A in the upper adhesive layer and relative permittivity B in the lower adhesive layer satisfy expression (1): [relative permittivity A≧relative permittivity B . . . (1)] at respective temperatures set in increments of 20° C. from −40° C. to 80° C., and a temperature dependency of the relative permittivity B in the lower adhesive layer as determined by a temperature dependency evaluation test is up to 30%.
