Abstract

A touch window according to one embodiment comprises: a substrate having an effective area and an ineffective area; a sensing electrode arranged in the effective area and sensing a position; and a wiring arranged in the effective area and the ineffective area and electrically connecting to the sensing electrode, wherein the wiring comprises a first wiring and a second wiring such that the first wiring and the second wiring are vertically arranged.

Claims

1. A touch window comprising:

a substrate comprising an active area and an unactive area;

a sensing electrode disposed on the active area to sense a position; and

wiring lines disposed on the active area and the unactive area to electrically connect the sensing electrode,

wherein the wiring lines comprise a first wiring line and a second wiring line, and the first wiring line and the second wiring line are vertically disposed.

2. The touch window of claim 1, further comprising an intermediate layer disposed between the first wiring line and the second wiring line.

3. The touch window of claim 1, wherein the first wiring line and the second wiring line are electrically connected to each other.

4. The touch window of claim 2, further comprising a hole formed through the intermediate layer.

5. The touch window of claim 4, wherein the first wiring line and the second wiring line are connected to each other through the hole.

6. The touch window of claim 1, wherein a portion of the first wiring line is disposed on the active area and makes contact with the sensing electrode.

7. The touch window of claim 1, wherein the second wiring line is connected to an external circuit.

8. The touch window of claim 2, wherein the intermediate layer comprises:

a first intermediate part disposed on the active area; and

a second intermediate part integrally formed with the first intermediate part and disposed on the unactive area.

9. The touch window of claim 1, wherein the sensing electrode comprises:

a reception electrode that receives a signal; and

a transmission electrode that transmits a signal, and

wherein the reception electrode and the transmission electrode are disposed on a same plane.

10. The touch window of claim 9, wherein ends of the second wiring line connected to the reception electrode and the transmission electrode, respectively, are disposed at a same end of the substrate.

11. A touch window comprising:

a substrate;

a deco layer on the substrate;

a sensing layer on the substrate; and

an intermediate layer on the deco layer,

wherein the touch window comprises wiring lines disposed on the intermediate layer to electrically connect the sensor electrode.

12. The touch window of claim 11, wherein the wiring lines comprise a first wiring line and a second wiring line which are vertically disposed.

13. The touch window of claim 12, wherein the first wiring line is disposed on the deco layer.

14. The touch window of claim 12, wherein the second wiring line is disposed on the intermediate layer.

15. The touch window of claim 12, wherein the intermediate layer comprises a first intermediate layer and a second intermediate layer on the first intermediate layer.

16. The touch window of claim 15, wherein the first intermediate layer is disposed on the deco layer.

17. The touch window of claim 15, wherein the second intermediate layer is disposed on the first wiring line.

18. The touch window of claim 12, further comprising a hole formed through the intermediate layer.

19. The touch window of claim 18, wherein the first wiring line and the second wiring line are connected to each other through the hole.

20. The touch window of claim 11, wherein the sensing electrode comprises:

a reception electrode that receives a signal; and

a transmission electrode that transmits a signal, and

wherein the reception electrode and the transmission electrode are disposed on a same plane.
