Abstract
A coordinate detecting device includes a resistive film formed over a substrate; and a common electrode formed over the resistive film for applying a voltage to the resistive film. The coordinate detecting device generates potential distribution in the resistive film by applying the voltage to the resistive film from the common electrode and detects a coordinate of a contact position of the resistive film by detecting a potential of the contact position of the resistive film. The substrate is formed of an insulator in a square shape. The common electrode is formed along an edge part of the substrate. The resistive film under the common electrode has one or more areas where the resistive film does not exist. An L-shaped resistive film absent area where the resistive film does not exist is provided in one or more corners of the substrate and on the same side of the common electrode as a side where a center of the substrate is situated.
