Abstract: A touch sensor includes a first sensing cell part and a first wiring part. The first sensing cell part arranges first sensing cell line groups by a first repetition number to be spaced apart in an X-axis direction. The first wiring part is formed in one outer bezel area in a Y-axis direction from the first sensing cell part. The first wiring part includes a first outgoing wire group connected to the first sensing cell line group and a first dummy wire group not connected to the first sensing cell line group.

Abstract: A touch sensor comprises a group pattern having a sensing cell part including a plurality of sensing cell groups in which a plurality of sensing cells are electrically connected and a wiring part formed outside the sensing cell part. The wiring part includes a first sub-wiring part and a second sub-wiring part. The first sub-wiring part has a drawing wire electrically connected to a sensing cell at one end of the sensing cell group. The second sub-wiring part is disposed outside the first sub-wiring part and has a non-drawing wire not electrically connected to the sensing cell part. The non-drawing wires are provided as many as the number of unit patterns repeatedly formed to constitute a large-area touch sensor minus one.
