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.
