Abstract

Disclosed herein is a touch panel. The touch panel 100 according to a preferred embodiment of the present invention includes an electrode pattern 110 formed of a combination of unit patterns 113 in which an intersecting region 117 in which sides 115 intersect each other and a width of the side 115 in the intersecting region 117 is smaller than a width of the side 115 outside the intersecting region 117.

Claims

1. A touch panel, comprising:

an electrode pattern formed of a combination of unit patterns in which an intersecting region in which sides intersect each other is formed and a width of the side in the intersecting region is smaller than a width of a side outside the intersecting region.

2. The touch panel as set forth in claim 1, wherein the sides intersect each other at an angle more or less than 90°

.

3. The touch panel as set forth in claim 1, wherein the unit pattern is a diamond shape.

4. The touch panel as set forth in claim 1, wherein the width of the side outside the intersecting region is constant.

5. The touch panel as set forth in claim 1, further comprising:

a transparent substrate on which the electrode pattern is formed.

6. The touch panel as set forth in claim 1, wherein the electrode pattern is formed of copper (Cu), aluminum (Al), gold (Au), silver (Ag), titanium (Ti), palladium (Pd), and chromium (Cr), or a combination thereof.

7. The touch panel as set forth in claim 1, wherein the electrode pattern is formed of metal silver formed by exposing/developing a silver salt emulsion layer.

8. A touch panel, comprising:

an electrode pattern formed of a combination of unit patterns in which an intersecting region in which sides intersect each other is formed and a width of the side is reduced toward the intersecting region.

9. The touch panel as set forth in claim 8, wherein the sides intersect each other at an angle more or less than 90°

.

10. The touch panel as set forth in claim 8, wherein the unit pattern is a diamond shape.

11. The touch panel as set forth in claim 8, wherein the width of the side is reduced step-by-step toward the intersecting region.

12. The touch panel as set forth in claim 8, further comprising:

a transparent substrate on which the electrode pattern is formed.

13. The touch panel as set forth in claim 8, wherein the electrode pattern is formed of copper (Cu), aluminum (Al), gold (Au), silver (Ag), titanium (Ti), palladium (Pd), and chromium (Cr), or a combination thereof.

14. The touch panel as set forth in claim 8, wherein the electrode pattern is formed of metal silver formed by exposing/developing a silver salt emulsion layer.
