Abstract
A capacitive touch panel that detects an input position accurately with a limited number of sensing electrodes is provided. First and second sensing electrodes adjacent to each other in a detecting direction are arranged such that among a plurality of branch patterns of the first sensing electrode a branch pattern closer to the second sensing electrode, and among a plurality of branch patterns of the second sensing electrode a branch pattern closer to the first sensing electrode are alternately arranged in the detecting direction. The widths in the detecting direction of the plurality of branch patterns of each sensing electrode are set such that the branch patterns on the opposite sides in the detecting direction have the smallest width, and the width of a branch pattern gradually becomes greater as the branch pattern gets closer to a branch pattern at the center.
