An embodiment relates to a touch window.

[0002] In recent years, a touch window has been applied to input images in a manner of touching an input device such as a finger or a stylus to an image displayed on a display device in various electronic products.

Such a touch window may be formed by disposing electrodes on a substrate. For example, the electrode may be formed of a transparent electrode such as indium tin oxide (ITO) or a metal electrode to form a mesh electrode .

At this time, a protective layer or the like may be further disposed on the electrode. For example, the electrode may be provided with various functional layers for external impact and scattering prevention.

As a result, the thickness of the touch window is increased by the functional layer, and a plurality of processes are required.

Therefore, a touch window of a new structure capable of solving such a problem is required.

The embodiment seeks to provide a touch window with improved reliability and thinness.

A touch window according to an embodiment includes: a substrate; An electrode layer disposed on at least one surface of the one surface and the other surface of the substrate; And a protective layer disposed on the electrode layer, wherein the thickness of the protective layer is 2 占 퐉 to 30 占 퐉.

A touch window according to an embodiment includes a resin composition, and a protective layer having a thin thickness may be disposed on the electrode layer.

Further, such a resin composition can have adhesiveness and can function as a scattering-preventive function. The acrylic resin, the silicone resin, the acrylic resin, and the like can be prevented from cracking or disconnection due to external impacts due to the protective layer which is disposed while wrapping the electrode layer with good durability.

Further, since the protective layer can prevent scattering, adhesion, and protection of the electrodes at the same time, it is not necessary to arrange the respective functional layers, so that the thickness of the touch window can be reduced.

Thus, the touch window according to embodiments may have improved reliability and thinness by the protective layer.

Sapphire has excellent electrical properties such as dielectric constant, which not only greatly improves the speed of touch reaction but also can easily realize space touch such as hovering and is applicable as a cover substrate because of its high surface strength. Here, hovering means a technique of recognizing coordinates even at a small distance from the display.

Also, the cover substrate 110 may be curved with a partially curved surface. That is, the cover plate 110 may be partially flat and partially curved with a curved surface. In detail, the end of the cover substrate 110 may be curved with a curved surface or may have a curved surface with a curvature.

In addition, the cover substrate 110 may be a flexible substrate having a flexible property.

That is, the first sensing electrode 210 and the second sensing electrode 220 may be disposed on both sides of the substrate 100, respectively. Accordingly, since both the first sensing electrode 210 and the second sensing electrode 220 can be disposed on one substrate 100, the thickness of the touch window can be reduced.

The sensing electrode 200 may include a conductive material. For example, the sensing electrode 200 may include a transparent conductive material so that electricity can flow without disturbing the transmission of light.

For example, the sensing electrode 200 may include a transparent conductive material to allow electricity to flow without disturbing the transmission of light.

The mesh line having a line width of the mesh line LA of less than about 0.1 mu m may not be possible in the manufacturing process. When the mesh line LA is more than about 10 mu m, the sensing electrode pattern may be visually recognized from the outside, resulting in decreased visibility. Alternatively, the line width of the mesh line LA may be about 1 탆 to about 5 탆. Or, the line width of the mesh line may be about 1.5 탆 to about 3 탆.
