Abstract
A touch panel of capacitance type includes plural X-electrodes, plural Y-electrodes, and a Z-electrode. Each of the X-electrode and the Y-electrode is formed to have pad portions and thin line portions alternately arranged in an extending direction. The pad portion of the X-electrode and the pad portion of the Y-electrode are arranged without being overlapped in a planar view. The Z-electrode is electrically in a floating state, and formed to be overlapped with both the adjacent X-electrode and the Y-electrode in a planar view. The touched position is calculated based on a local minimal point as an intersection with the interelectrode capacitance value that is equal to or smaller than each of the interelectrode capacitance values of four peripheral intersections among those at the intersections between the plural X-electrodes and the plural Y-electrodes.
