Claim:
1. A touch sensor, comprising: a plurality of drive electrodes and a plurality of sense electrodes intersecting each other and having mutual capacitances formed among them; a plurality of dummy electrodes being disposed in a same layer as the drive electrodes and the sense electrodes, in a remaining area other than an area occupied by the drive electrodes and the sense electrodes, wherein each of the plurality of dummy electrodes is surrounded by either some of the plurality of drive electrodes or some of the plurality of sense electrodes but not by both; a plurality of first bridges and a plurality of second bridges located in a same layer wherein the plurality of dummy electrodes are electrically connected by the plurality of second bridges; and wherein the plurality of drive electrodes separates each of the sense electrodes into a plurality of segments, the plurality of segments of a same sense electrode being electrically connected by the plurality of first bridges, the first bridges being insulated from the drive electrodes through an insulation layer, and the second bridges being insulated from the drive electrodes through the insulation layer; or the plurality of sense electrodes separates each of the drive electrodes into a plurality of segments, the plurality of segments of a same drive electrode being electrically connected by the plurality of first bridges, the first bridges being insulated from the sense electrodes through an insulation layer, and the second bridges being insulated from the sense electrodes through the insulation layer.
