Touch window
This invention relates to a touch window. The touch window includes a substrate; a plurality of sensing electrodes on the substrate; and an opening part between the sensing electrodes. In addition, the touch window has an opening part formed between the electrode parts, so that the electrode parts may be prevented from being short-circuited with each other.
1. A touch window comprising:
a substrate including an active area and an unactive area;
a sensing electrode on the active area of the substrate; and
a wire electrode electrically connected to the sensing electrode on the unactive area of the substrate,
wherein the sensing electrode includes a plurality of first sensing electrodes extending in a first direction and a plurality of second sensing electrodes extending in a second direction crossing the first direction,
wherein a first one of the first sensing electrodes includes a first sensing electrode pattern and a second one of the first sensing electrodes includes a second sensing electrode pattern,
wherein the first sensing electrode pattern includes a plurality of first mesh lines and a plurality of first mesh openings, and the second sensing electrode pattern includes a plurality of second mesh lines and a plurality of second mesh openings,
an opening part extends in the first direction, and the opening part is provided between the first sensing electrode pattern of the first one of the first sensing electrode pattern and the second sensing electrode pattern of the second one of the first sensing electrode pattern,
wherein a width of the opening part, in the second direction, is within a range of 1 μm to 500 μm.
2. The touch window of claim 1 , wherein the opening part exposes the substrate.
3. The touch window of claim 1 , wherein some portion of the opening part is formed in the first direction parallel to the wire electrode.
4. The touch window of claim 1 , the plurality of first sensing electrodes include at least one of Cr, Ni, Cu, Al, Ag, Mo, Au, Ti and the alloy thereof.
5. The touch window of claim 1 , the sensing electrodes are disposed to make direct contact with the substrate.
6. The touch window of claim 1 , wherein a mesh line is not provided within the opening part.
7. The touch window of claim 1 , wherein a line width of one of the first mesh lines is within a range of 0.1 μm to 10 μm.
8. The touch window of claim 1 , wherein the width of the opening part is different than a line width of one of the first mesh lines.
9. The touch window of claim 1 , wherein the width of the opening part is different than a distance between two adjacent ones of the first mesh lines.
10. The touch window of claim 9 , wherein the width of the opening part is less than the distance between the two adjacent ones of the first mesh lines.
11. The touch window of claim 1 , comprising a cover substrate on the substrate.
12. The touch window of claim 1 , wherein a shape of the first mesh openings has a rectangular shape, a diamond shape, a pentagonal shape or a hexagonal shape, or a circular shape.
13. The touch window of claim 1 , wherein a shape of one of the first sensing electrode patterns has a stripe shape, and wherein the opening part has a stripe shape.
14. The touch window of claim 1 , wherein the width of the opening part is constant along a length of the opening part from the first end to the second end.
15. The touch window of claim 1 , wherein the width of the opening part is within a range of 350 μm to 500 μm.
16. The touch window of claim 1 , comprising a wire pad part that extends in the second direction, the first sensing electrode pattern to connect to the wire pad part, and the wire pad part to connect to the wire electrode.
17. The touch window of claim 1 , wherein the width of the opening part is constant from the first end to the second end.
