Abstract

A touch window includes a substrate; and an electrode on the substrate, wherein the electrode includes a first mesh line extending in a first direction and having a first width; a second mesh line extending in a direction different from the first direction and having a second width; and an cross area in which the first and second mesh lines cross each other, the cross area having a third width, wherein the third width is larger than the first width, and the third width is equal to or less than 10 times of the first width.

First claim

What is claimed is:

1 . A touch window comprising:
a substrate; and an electrode on the substrate, wherein the electrode comprises: a first mesh line extending in a first direction and having a first width; a second mesh line extending in a direction different from the first direction and having a second width; and an cross area in which the first and second mesh lines cross each other, the cross area having a third width, wherein the third width is larger than the first width, and the third width is equal to or less than 10 times of the first width.

2 . The touch window of claim 1 , wherein the first width corresponds to the second width.

3 . The touch window of claim 1 , wherein at least one of the first and second mesh lines has one end having a width gradually narrowed toward the cross area.

4 . The touch window of claim 1 , wherein the substrate includes an active area and an unactive area,
the electrode includes a sensing electrode disposed on the active area; and a wire electrode disposed on the unactive area, and at least one of the sensing and wire electrodes has a mesh shape.

5 . A touch window comprising:
a substrate; and an electrode on the substrate, wherein the electrode comprises: a first mesh line extending in a first direction; and a second mesh line extending in a direction different from the first direction and crossing the first mesh line, wherein the first and second mesh lines cross each other at an angle in a range of 60° to 120°.

6 . The touch window of claim 5 , wherein at least one of the first and second mesh lines has a curved line.

7 . The touch window of claim 6 , wherein the first or, second mesh line includes a linear line.

8 . The touch window of claim 5 , wherein the first mesh line includes a first sub-mesh line and a second sub-mesh line spaced apart from each other by a first interval distance, and
the first interval distance varies in the first direction.

9 . The touch window of claim 5 , wherein the substrate includes an active area and an unactive area,
the electrode includes a sensing electrode disposed on the active area, and at least one of the sensing and wire electrodes has a mesh shape.

10 . The touch window of claim 9 , wherein the sensing electrode includes a first sensing electrode extending in one direction; and
a second sensing electrode extending in a direction different from the one direction, and the first and second sensing electrodes are disposed on at least one of one surface and an opposite surface of the substrate.

11 . A touch window comprising:
a substrate; an electrode layer disposed on at least one of one surface and an opposite surface of the substrate; and a protective layer on the electrode layer, wherein the protective layer has a thickness in a range of 2 μm to 30 μm.

12 . The touch window of claim 11 , wherein the protective layer includes an adhesive material.

13 . The touch window of claim 12 , wherein the protective layer includes acrylic resin.

14 . The touch window of claim 11 , wherein the protective layer makes direct contact with the electrode layer.

15 . The touch window of claim 11 , wherein the protective layer surrounds the electrode layer.

16 . The touch window of claim 11 , wherein the electrode layer includes a first sensing electrode and a second sensing electrode,
the first and second sensing electrodes are disposed on a same surface of the substrate, and the protective layer is disposed on the first and second sensing, electrodes.

17 . The touch window of claim 11 , wherein the electrode layer includes a first sensing electrode and a second sensing electrode,
the first sensing electrode is disposed on one surface of the substrate, the second sensing electrode is disposed on an opposite surface of the substrate, and the protective layer is disposed on at least one of the first and second sensing electrodes.

18 . The touch window of claim 11 , wherein the substrate includes a first substrate and a second substrate,
the electrode layer includes a first sensing electrode and a second sensing electrode, the first sensing electrode is disposed on one surface of the first substrate, the second sensing electrode is disposed on one surface of the second substrate, and the protective layer is disposed on at least one of the first and second sensing electrodes.

19 . The touch window of claim 16 , wherein at least one of the first and second electrodes has a mesh shape.

20 . The touch window of claim 11 , wherein the substrate includes an active area and an unactive area, and
the protective layer is disposed on at least one of the active and unactive areas.
