Abstract

A touch panel has an active area and a non-active area disposed at an outer side of the active area defined therein. The touch panel includes a support member and a conductive layer formed on the support member and including an electrode part in the active area to sense touch and a wiring part disposed in the non-active area to be connected to the electrode part. In the non-active area, the wiring part is disposed on the support member and the electrode part is partially disposed on the wiring part.

Claims (18)

1. A touch panel having an active area and a non-active area formed at an outer side of the active area defined therein, the touch panel comprising:

a support member; and

a conductive layer formed on the support member and comprising an electrode part in the active area to sense touch and a wiring part disposed in the non-active area to be connected to the electrode part,

wherein, in the non-active area, the wiring part is disposed on the support member and the electrode part is partially disposed on the wiring part,

wherein the electrode part comprises a sensor part disposed in the active area and a wiring connection part electrically connected to the sensor part and disposed in the non-active area,

wherein the wiring part comprises an electrode connection part disposed between the wiring connection part and the support member and a wiring extending from the wiring connection part,

wherein a width of the wiring connection part is identical to or smaller than a width of the electrode connection part at a portion at which the wiring connection part and the electrode connection part are stacked,

wherein the electrode part comprises a first electrode extending in a first direction and a second electrode extending in a second direction different from the first direction within the active area,

wherein the support member comprises a first base member and a second base member spaced apart from the first base member, and

wherein the conductive layer comprises a first conductive layer on the first base member and a second conductive layer on the second base member, and further comprising:

a first seed layer formed between the first base member and the first conductive layer; and

a second seed layer formed between the second base member and the second conductive layer.

2. The touch panel according to claim 1 , wherein the electrode connection part is formed between the wiring connection part and the support member to be in contact with the wiring connection part and the support member.

3. The touch panel according to claim 2 , wherein the electrode part comprises a transparent conductive material comprising nanowires having a network structure.

4. The touch panel according to claim 3 , wherein the wiring part comprises a metal layer formed by deposition.

5. The touch panel according to claim 4 , wherein the wiring has a narrower width than the electrode connection part.

6. The touch panel according to claim 5 , wherein the electrode connection part has a width of about 1 mm to about 5 mm, and the wiring has a width of about 10 μm to about 100 μm.

7. The touch panel according to claim 6 , wherein the wiring has a width of about 30 μm to about 60 μm.
