ABSTRACT:
A coordinate detecting device is disclosed. The coordinate detecting device includes a resistance film, a common electrode which applies electric potential to the resistance film, a voltage supplying section which supplies a voltage to the common electrode, wiring which supplies the voltage to the voltage supplying section, an insulation film disposed between the common electrode and the resistance film, and an electric potential supplying section formed in the insulation film for supplying the electric potential from the common electrode to the resistance film. The coordinate detecting device detects a coordinate of a position on a panel when a user touches the position while an electric potential distribution is generated in the resistance film by being applied electric potential from the common electrode.
