Abstract: A touch sensor according to an embodiment of the present invention includes a base layer, a first electrode layer including first dummy electrodes and first sensing electrodes including first holes therein arranged on a top surface of the base layer, the first sensing electrodes, an insulating interlayer formed on the base layer and covering the first electrode layer, and a second electrode layer including second dummy electrodes and second sensing electrodes including second holes therein arranged on a top surface of the insulating interlayer. An electrode visual recognition can be suppressed by an overlapping arrangement of the holes and the electrode patterns.

Abstract: A touch sensor according to an embodiment of the present invention includes a base layer, a bridge electrode disposed on a top surface of the base layer, auxiliary electrodes disposed around the bridge electrode to be physically spaced apart from the bridge electrode, first sensing electrodes electrically connected to each other via the bridge electrode, and second sensing electrodes electrically separated from the first sensing electrodes and arranged in a direction different from an arrangement direction of the first sensing electrodes. A resistance may be decreased and a visual recognition of the bridge electrode may be suppressed using the auxiliary electrodes.
