Abstract:
A touch panel comprising an upper substrate of a soft film having an upper resistor film and a lower substrate of a hard plate having a lower resistor film, the upper substrate and the lower substrate being bonded together to face each other, the touch panel providing a detection output representing a position of contact between the upper resistor film and the lower resistor film as two-dimensional coordinate values,wherein both the upper resistor film and the lower resistor film are of a comb shape having a plurality of resistive lines with a common connector at one end, and the resistive lines of the upper resistor film and the resistive lines of the lower resistor film extend to intersect each other; wherein a lower resistor film connector or an upper resistor film connector is formed on the upper substrate or the lower substrate for electrically connecting with the common connector of the other substrate; and wherein the common connector is coated with a protection film which protects the common connector from intrusion of moisture externally so that deterioration of resistance characteristics of the common connector is prevented.
