Abstract

Disclosed is a touch window. The touch window includes a substrate, a sensing electrode on the substrate, and a wire to electrically connect the sensing electrode, and a dummy part is provided in the wire. The touch window includes a substrate, a sensing electrode on the substrate, and a wire to electrically connect the sensing electrode. The wire includes a first wire part and a second wire part adjacent to the first wire part, and the first wire part has a directionality different from a directionality of the second wire part.

First claim

The invention claimed is:

1. A touch window comprising:
a substrate;
a sensing electrode on the substrate; and
a wire to electrically connect the sensing electrode,
wherein the wire is provided therein with a dummy part,
wherein the wire has a first pattern and the dummy part has a second pattern in the wire,
wherein the second pattern is inclined with respect to the first pattern,
at least one surface of the dummy part form a first angle θ 1 together with one surface of the wire, and
wherein the first angle θ 1 is in a range of 0.1° to 50°.

2. The touch window of claim 1 , wherein the first pattern is an intaglio pattern, and the second pattern is an emboss pattern.

3. The touch window of claim 1 , wherein the dummy part comprises a plurality of protrusions.

4. The touch window of claim 1 , wherein the wire comprises a first wire part and a second wire part adjacent to the first wire part, and the first wire part has a directionality different from a directionality of the second wire part.

5. The touch window of claim 4 , wherein the second wire part is bent from the first wire part while extending from the first wire part.

6. The touch window of claim 4 , wherein the directionality of the first wire part or the second wire part is different from a directionality of the sensing electrode.

7. The touch window of claim 1 , wherein the wire includes chrome (Cr), nickel (Ni), copper (Cu), aluminum (Al), silver (Ag), molybdenum (Mo), or the alloy thereof.

8. The touch window of claim 1 , wherein the wire includes a metal paste material.

9. The touch window of claim 1 , an electrode pad provided at an end of the wire and connected with a circuit board.

10. A touch window comprising:
a substrate;
a sensing electrode on the substrate;
a wire to electrically connect the sensing electrode; and
an electrode pad provided at an end of the wire and connected with a circuit board,
wherein the electrode pad is provided therein with a dummy part,
wherein an angle between the electrode pad and the dummy part is in a range of 10° to 170°.

11. The touch window of claim 10 , wherein the wire comprises a first wire part and a second wire part adjacent to the first wire part, and the first wire part has a directionality different from a directionality of the second wire part,
wherein an angle between the first and second wire parts is in a range of 10° to 170°.

12. The touch window of claim 11 , a length of the first wire part is different from a length of the second wire part.

13. The touch window of claim 10 , wherein a line width of the electrode pad is larger than a line width of the wire.

14. The touch window of claim 10 , wherein the electrode pad is formed by filling a conductive material in an intaglio pattern.

15. The touch window of claim 10 , wherein the electrode pad includes a metal paste material.

16. The touch window of claim 10 , wherein the wire includes chrome (Cr), nickel (Ni), copper (Cu), aluminum (Al), silver (Ag), molybdenum (Mo), or the alloy thereof.

17. A touch window comprising:
a substrate;
a sensing electrode on the substrate;
a wire to electrically connect the sensing electrode; and
an electrode pad provided at an end of the wire and connected with a circuit board,
wherein the electrode pad is provided therein with a dummy part,
wherein the electrode pad comprises a first electrode pad and a second electrode pad having mutually different directionalities.

18. The touch window of claim 17 , an angle between the second electrode pad and the first electrode pad is in a range of 10° to 170°.

19. The touch window of claim 17 , wherein at least one of the first and second electrode pads is inclined from an edge of the substrate.

20. The touch window of claim 17 , wherein the directionality of the first electrode pad or the second electrode pad is different from a directionality of the sensing electrode.
