Abstract:
1. A coordinate detecting device comprising: a substrate formed of an insulator; a resistive film formed over the substrate; and a common electrode formed along four sides of the substrate over the resistive film for applying a voltage to the resistive film, wherein the resistive film includes resistive film absent areas where the resistive film does not exist, said resistive film absent areas being arranged along the four sides of the substrate, and L-shaped resistive film absent areas formed apart from each other at each corner of the substrate, the L-shaped resistive film absent areas are provided on the substrate more inwardly than any of the resistive film absent areas and the common electrode; and the resistive film absent areas located along any one of the four sides are arranged so as to have pitches which become narrower toward a center part of the any one of the four side of the substrate.
