Also, the second region 2A may be overlapped with the third region 4A and the fourth region 4A. In detail, the second region 2A may partially overlap the third region 4A and the fourth region 4A.

That is, the first region 1A, the second region 2A, the third region 3A, and the fourth region 4A, which are not overlapped or overlapped with each other, are defined in the substrate 100 .

Referring to FIG. 4, the substrate 100 may have a plurality of quadrants defined by a first axis AX1 and a second axis AX2 orthogonal to the first axis AX1.

The intersection point of the first axis AX1 and the second axis AX2 may correspond to the center point C of the substrate 100. That is, the intersection point of the first axis AX1 and the second axis AX2, that is, the orthogonal point, may coincide with the center point C of the substrate 100.

Or, the intersection of the first axis AX1 and the second axis AX2, that is, the orthogonal point may not correspond to the center point C of the substrate 100. That is, the intersection of the first axis AX1 and the second axis AX2, that is, the orthogonal point may not coincide with the center point C of the substrate 100.

The center of gravity may be overlapped with the center point (C). The center of gravity may correspond to the center point (C). The center of gravity may not overlap with the center point C. The center of gravity may not correspond to the center point C.

In detail, the substrate 100 has a first quadrant Q1, a second quadrant Q2, a third quadrant Q3 and a fourth quadrant Q4 defined by the first axis and the second axis. .

The first quadrant Q1, the second quadrant Q2, the third quadrant Q3, and the fourth quadrant Q4 may be disposed adjacent to each other. The first quadrant Q1, the second quadrant Q2, the third quadrant Q3, and the fourth quadrant Q4 may be integrally formed.

The first sensing electrode may be connected at one end and the other end of the first sensing electrode and the first sensing electrode may be connected at one end of the first sensing electrode to the first sensing electrode, And the first axis may be defined in a boundary region connected to the other end of the first sensing electrode.

The sensing electrode may include a first sensing electrode and a second sensing electrode.

The first sensing electrode and the second sensing electrode may extend in different directions. In detail, the first sensing electrode extends in one direction, and the second sensing electrode extends in a direction different from the first direction.

For example, the first sensing electrode may extend in a direction in which the first axis 1AX extends. The first sensing electrode may extend in a direction parallel to a direction in which the first axis 1AX extends. The first sensing electrode may extend in the same direction as the first axis AX1 extends.

The second sensing electrode may extend in a direction different from the first sensing electrode. The second sensing electrode may extend in a direction intersecting with the first sensing electrode. The second sensing electrode may extend in a direction in which the second axis AX2 extends. The second sensing electrode may extend in a direction parallel to a direction in which the second axis AX2 extends. The second sensing electrode may extend in the same direction as the direction in which the second axis AX2 extends.

The first sensing electrode and the second sensing electrode may be disposed on the same side of the substrate 100. For example, the first sensing electrode and the second sensing electrode are disposed on the same surface of the substrate 100, and an insulating layer or the like is disposed on a region where the first sensing electrode overlaps with the second sensing electrode So that the first sensing electrode and the second sensing electrode can be prevented from being electrically connected to each other.

However, the embodiment is not limited thereto, and the first sensing electrode and the second sensing electrode may be disposed on the other side of the substrate. For example, the first sensing electrode may be disposed on one side of the substrate, and the second sensing electrode may be disposed on a side opposite to the first side of the substrate. That is, the first sensing electrode and the second sensing electrode may be disposed on both sides of the substrate, respectively.

The sensing electrode may include a conductive material. For example, the sensing electrode 200 may include a transparent conductive material to allow electricity to flow without disturbing the transmission of light. For example, the sensing electrode may include indium tin oxide, And may include metal oxides such as indium zinc oxide, copper oxide, tin oxide, zinc oxide, and titanium oxide. Thus, since the transparent material is disposed on the effective region, the degree of freedom in forming the electrode pattern of the sensing electrode can be improved.

Alternatively, the sensing electrode may comprise a nanowire, a photosensitive nanowire film, a carbon nanotube (CNT), a graphene, a conductive polymer, or a mixture thereof. Accordingly, when manufacturing a touch window in which flexible and / or bending is implemented, the degree of freedom can be improved.

When nanocomposites such as nanowires or carbon nanotubes (CNTs) are used, they may be made of black. The color and reflectance can be controlled while securing the electric conductivity by controlling the content of the nano powder.

Alternatively, the sensing electrode may comprise various metals. For example, the sensing electrode may be made of Cr, Ni, Cu, Al, Ag, or Mo. Gold (Au), titanium (Ti), and alloys thereof. Accordingly, when manufacturing a touch window in which flexible and / or bending is implemented, the degree of freedom can be improved.

In addition, the sensing electrode may include a plurality of mesh lines and a mesh opening formed by the mesh lines.

The line width of the mesh line may be about 0.1 탆 to about 10 탆. The mesh line having a line width of less than about 0.1 탆 may not be formed in a manufacturing process or may short-circuit the mesh line. If the mesh line is more than about 10 탆, the electrode pattern may be visually recognized from the outside and visibility may be deteriorated. Preferably, the linewidth of the mesh wire may be between about 0.5 microns and about 7 microns. More preferably, the linewidth of the mesh wire may be between about 1 [mu] m and about 3.5 [mu] m.

Further, the thickness of the mesh line may be about 100 nm to about 500 nm. If the thickness of the mesh wire is less than about 100 nm, the electrode resistance may increase and the electrical characteristics may deteriorate. If the mesh wire thickness exceeds about 500 nm, the overall thickness of the touch window may become thick and the process efficiency may be deteriorated. Preferably, the thickness of the mesh line may be from about 150 nm to about 200 nm. More preferably, the thickness of the mesh line may be from about 180 nm to about 200 nm.

In addition, the mesh opening may be formed in various shapes. The mesh openings may have various shapes such as a diamond shape, a pentagon shape, a hexagonal shape, a polygonal shape, a circular shape, and the like. In addition, the mesh opening OA may be formed in a regular shape or a random shape.

The width of the mesh opening may be about 100 [mu] m to about 500 [mu] m. In detail, the width of the mesh opening may be about 150 탆 to about 400 탆. More specifically, the width of the mesh opening may be from about 200 [mu] m to about 300 [mu] m.

If the width of the mesh opening is less than about 100 탆, the mesh lines may come into contact with each other due to an error in the process, and when the width exceeds about 500 탆, the overall size of the electrode pattern portion may be increased , Visibility may be lowered.

Since the electrode pattern portions have a mesh shape, it is possible to prevent the pattern of the sensing electrode from being visible on the display region as an effective region. That is, even if the sensing electrode is formed of metal, the pattern can be made invisible. In addition, the resistance of the touch window can be lowered even when the sensing electrode is applied to a touch window of a large size.
