Description

TOUCH WINDOW AND TOUCH DEVICE "

Embodiments relate to a touch window and a touch device.

2. Description of the Related Art In recent years, a touch panel has been applied in a variety of electronic products in which a finger or an input device such as a stylus is contacted.

The touch panel is typically divided into a resistive touch panel and a capacitive touch panel. The resistance film type touch panel senses that the resistance changes according to the connection between the electrodes when the pressure is applied to the input device, and the position is detected. A capacitance type touch panel senses a change in electrostatic capacitance between electrodes when a finger touches them, thereby detecting the position. Considering the convenience of the manufacturing method and the sensing power, recently, in a small model, the electrostatic capacity method has attracted attention.

The touch panel may include a sensing electrode and a wiring connected to the sensing electrode. Further, such a touch panel may include a cover substrate arranged on the uppermost side. The sensing electrode and the wiring may be disposed on the back surface of the cover substrate. However, when the sensing electrode and the wiring are disposed on the cover substrate, it is difficult to drive the sensing electrode and the wiring when the cover substrate is broken.

Accordingly, the sensing electrode and the wiring may be disposed on a separate substrate other than the cover substrate. However, there is a problem that the thickness of the separate substrate is increased and the thickness of the touch panel is increased.

Embodiments provide a touch window and a touch device with improved reliability.

A touch window according to an embodiment includes a substrate divided into a valid region and a non-valid region and formed of a photo-curable resin; A sensing electrode disposed on an effective region of the substrate; A cover substrate disposed on the substrate; And an adhesive layer disposed between the substrate and the cover substrate.

Further, a touch device according to an embodiment includes: a display panel including a first display substrate and a second display substrate; A touch substrate disposed on the display panel and formed of a photo-curing resin; A cover substrate disposed on the touch substrate; A first sensing electrode formed on at least one surface of the first display substrate or the second display substrate; And a second sensing electrode disposed on the touch substrate.

The touch window and the touch device according to the embodiments can be implemented and operated even if the cover substrate is damaged or damaged. In addition, since the substrate supporting the sensing electrodes and the wiring is formed of resin, the thickness of the touch window and the touch device according to the embodiment can be reduced.

In addition, since electrodes are formed on a substrate formed of resin without forming electrodes directly on the cover substrate, it is possible to prevent the cover substrate from being weakened during the electrode formation process. As a result, the rigidity of the cover substrate can be ensured and scattering can be prevented. Further, since the substrate formed of resin is disposed on the back surface of the cover substrate, there is an effect of increasing the strength of the touch window and the touch device according to the embodiment.

In addition, the flexibility of the substrate formed of resin can be ensured, and the flexible, curved, or bent characteristics of the touch window and the touch device according to the embodiments can be improved.

In the description of the embodiments, it is to be understood that each layer (film), area, pattern or structure may be referred to as being "on" or "under / under" Quot; includes all that is formed directly or through another layer. The criteria for top / bottom or bottom / bottom of each layer are described with reference to the drawings.

Also, when a part is referred to as being "connected" to another part, it includes not only a case of being "directly connected" but also a case of being "indirectly connected" with another member in between. Also, when an element is referred to as "comprising ", it means that it can include other elements, not excluding other elements unless specifically stated otherwise.

The thickness or the size of each layer (film), region, pattern or structure in the drawings may be modified for clarity and convenience of explanation, and thus does not entirely reflect the actual size.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

First, a touch window according to the first embodiment will be described with reference to FIGS. 1 to 5. FIG. 1 is an exploded perspective view of a touch window according to the first embodiment. 2 is a sectional view of a touch window according to the first embodiment. 3 to 5 are views for explaining a method of manufacturing the touch window according to the first embodiment.

Referring to FIGS. 1 and 2, the touch window according to the first embodiment includes a first substrate 101 and a second substrate 102 that are divided into a valid area AA and a non-valid area UA. The second substrate 102 may be disposed on the first substrate 101. A first adhesive layer 61 may be disposed between the second substrate 102 and the first substrate 101. The first adhesive layer 61 may include an optically clear adhesive (OCA) or an optically clear resin (OCR).

In the effective area AA, a display may be displayed. Also, the display may not be displayed in the non-effective area UA disposed around the effective area AA.

In addition, the position of the input device (e.g., a finger or the like) can be sensed in at least one of the valid area AA and the ineffective area UA. When an input device such as a finger is brought into contact with such a touch window, a capacitance difference occurs at a portion where the input device is contacted, and a portion where such a difference occurs can be detected as the contact position.

For example, in the effective area AA, the sensing electrode 200 may be formed to sense the input device. A wiring 300 electrically connecting the sensing electrode 200 may be formed in the non-effective area UA. Although not shown in the drawing, a circuit board or the like connected to the wiring 300 may be located in the ineffective area UA.

A cover substrate 400 may be disposed on the second substrate 102. A second adhesive layer 62 may be disposed between the second substrate 102 and the cover substrate 400. The second adhesive layer 62 may include an optically clear adhesive (OCA) or an optically clear resin (OCR).

The cover substrate 400 may be rigid or flexible. For example, the cover substrate 400 may comprise glass or plastic. In detail, the cover substrate 400 may include chemically tempered glass such as soda lime glass or aluminosilicate glass, or may include plastic such as polyethylene terephthalate (PET) or polyimide (PI) It may contain sapphire.

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.

In addition, the cover substrate 400 may be curved with a partially curved surface. That is, the substrate may be partially flat and partially curved with a curved surface. In detail, the end of the cover substrate 400 may be curved or curved with a curved surface or a curved surface including a random curvature.

The first substrate 101 and the second substrate 102 may support the sensing electrode 200, the wiring 300, and the circuit substrate formed thereon. At least one substrate of the first substrate 101 and the second substrate 102 may be formed of a resin. In detail, at least one substrate of the first substrate 101 and the second substrate 102 may be formed of a photo-curing resin. In addition, the substrate not formed of resin may be formed of various materials capable of supporting the sensing electrode 200, the wiring 300, and the circuit board formed thereon.

That is, the first substrate 101 and the second substrate 102 may be formed of the same material. At this time, the first substrate 101 and the second substrate 102 may be formed of resin.

In addition, the first substrate 101 and the second substrate 102 may be formed of different materials. At this time, the first substrate 101 or the second substrate 102 may be formed of resin, and the other substrate may be formed of another material. Preferably, the second substrate 102 is formed of resin, and the first substrate 101 may be formed of another material.

At this time, the first substrate 101 may include plastic. For example, the first substrate 101 may include a reinforced or soft plastic such as polyethylene terephthalate (PET) or polyimide (PI). In addition, the first substrate 101 may include an optically isotropic film. For example, the first substrate 101 may include a Cyclic Olefin Copolymer (COC), a Cyclic Olefin Polymer (COP), a polycarbonate (PC) or a light polymethyl methacrylate (PMMA) have. In addition, the first substrate 101 may include sapphire.

For example, the first substrate 101 or the second substrate 102 may be formed of resin, and the second substrate 102 or the first substrate 101 may be a plastic substrate. Preferably, the second substrate 102 is formed of a resin, and the first substrate 101 may be a plastic substrate.

That is, the second substrate 102 may be formed of resin, and the first substrate 101 may be formed of a material having a higher rigidity than the second substrate 102. Therefore, the touch window can be disposed at the uppermost and lowermost sides of the cover substrate 400 and the first substrate 101, where the rigidity is ensured, so that the strength can be improved and the reliability can be improved.

In the case where the first substrate 101 and the second substrate 102 are both formed of a plastic substrate such as polyethylene terephthalate (PET) Thick. That is, when a pattern such as the sensing electrode 200 and the wiring 300 is formed directly on a plastic substrate through a patterning process such as a photolithography process, the substrate needs to have a thickness of at least 50 μm or more. Therefore, it is difficult to secure the flexibility of the substrate, and it is difficult to reduce the thickness of the touch window and the touch device.

Accordingly, the touch window according to the embodiment includes at least one substrate formed of resin, so that the flexibility of the substrate and the touch window can be secured. In addition, the substrate formed of the resin may be formed to a thickness of 0.5 to 50 탆. Preferably, it may be formed to a thickness of 0.5 to 20 mu m. More preferably, it may be formed to a thickness of 1 to 10 mu m. That is, the substrate formed of the resin can be reduced in thickness as compared with the plastic substrate.

Particularly, when the second substrate 102, which is disposed between the cover substrate 400 and the second adhesive layer 62, is made of resin, the strength of the touch window is increased.

Wirings 300 are formed on the ineffective area UA of the first substrate 101 and the second substrate 102. The wiring 300 may apply an electrical signal to the sensing electrode 200. The wiring 300 may include a first wiring 310 and a second wiring 320. The first wiring 310 may be formed on the first substrate 101 and the second wiring 320 may be formed on the second substrate 102. The wiring 300 may be formed in the ineffective area UA so as not to be seen.

Meanwhile, although not shown in the drawing, a circuit board connected to the wiring 300 may further be positioned. As the circuit board, various types of printed circuit boards can be applied. For example, a flexible printed circuit board (FPCB) or the like can be applied.

An outer dummy layer (not shown) may be formed on the ineffective area UA of the first substrate 101 and the second substrate 102. However, the present invention is not limited thereto, and the outer dummy layer may be formed on the cover substrate 400. The outer dummy layer may be formed by applying a material having a predetermined color so that the wiring 300 and a printed circuit board connecting the wiring 300 to an external circuit can not be seen from the outside. The outer dummy layer may have a color suitable for a desired appearance, for example, a black color including black pigment and the like. A desired logo can be formed on the outer dummy layer by various methods. Such an outer dummy layer can be formed by vapor deposition, printing, wet coating or the like.

The sensing electrode 200 may be formed on the effective area AA of the first substrate 101 and the second substrate 102. The sensing electrode 200 may be disposed on the effective area AA to sense a touch. That is, the sensing electrode 200 can sense whether an input device such as a finger is in contact.

When the sensing electrode 200 and the wiring 300 are formed on the rear surface of the cover substrate 400, it is difficult to drive the sensing electrode 200 and the wiring 300 when the cover substrate 400 is broken. There was a problem. In addition, when patterns such as the sensing electrodes 200 and the wirings 300 are formed directly on the cover substrate 400 through a patterning process such as a photolithography process, the strength of the cover substrate 400 may be reduced. Further, there is a problem that the overall strength of the touch window is lowered and reliability is lowered.

Accordingly, the touch window according to the embodiment includes the sensing electrode 200 and the wiring 300 formed on the first substrate 101 and the second substrate 102. That is, the cover substrate 400 is prevented from being damaged in the process of forming the sensing electrode 200 and the wiring 300, and the strength is prevented from being weakened.

Thus, the scattering-preventing property of the cover substrate 400 can be imparted, and rigidity can be ensured. In addition, the touch window according to the embodiment can have improved reliability. That is, even if the cover substrate 400 is broken or damaged, touch implementation and driving can be performed.

The sensing electrode 200 may include a first sensing electrode 210 and a second sensing electrode 220. The first sensing electrode 210 may be formed on the first substrate 101 and the second sensing electrode 220 may be formed on the second substrate 102.

Although the first sensing electrode 210 and the second sensing electrode 220 are formed on the upper surface of the first substrate 101 and the second substrate 102 in the drawing, At least one sensing electrode of the first sensing electrode 210 and the second sensing electrode 220 may be formed on the back surface of the first substrate 101 and the second substrate 102.

The first sensing electrode 210 may extend in a first direction on the effective region AA and the second sensing electrode 220 may extend in a second direction that is different from the first direction . At this time, the first direction and the second direction are perpendicular to each other.

In addition, although the first sensing electrode 210 and the second sensing electrode 220 are arranged in a rhombic shape in the drawing, The first sensing electrode 210 and the second sensing electrode 220 may be arranged in various shapes such as a bar, a triangle, a polygon such as a rectangle, a circle, a linear H-shape or an ellipse .

That is, the first sensing electrode 210 may be formed on the effective area AA of the first substrate 101, and the first wiring 310 may be formed on the non-effective area UA. The second sensing electrode 220 may be formed on the effective area AA of the second substrate 102 and the second wiring 320 may be formed on the non-effective area UA. Also, a circuit board or the like connected to the first wiring 310 and the second wiring 320 may be positioned.

The wiring 300 may include the same material as the sensing electrode 200 or may include different materials. The wirings 300 may be formed in the same process as the sensing electrode 200 or may be formed in different processes. The first sensing electrode 210, the second sensing electrode 220, the first wiring 310, and the second wiring 320 may include the same material or may include different materials. have.

The first sensing electrode 210 may be electrically connected to the first wiring 310. The first sensing electrode 210 and the first wiring 310 may be integrally formed. The first sensing electrode 210 and the first wiring 310 may be formed in the same process. That is, the first sensing electrode 210 and the first wiring 310 may be formed of the same material in the same layer.

The second sensing electrode 220 may be electrically connected to the second wiring 320. The second sensing electrode 220 and the second wiring 320 may be integrally formed. The second sensing electrode 220 and the second wiring 320 may be formed in the same process. That is, the second sensing electrode 220 and the second wiring 320 may be formed of the same material in the same layer.

The sensing electrode 200 may include a conductive material. The sensing electrode 200 may include a transparent conductive material. For example, the sensing electrode 200 may be formed of indium tin oxide, indium zinc oxide, copper oxide, tin oxide, zinc oxide, Titanium oxide, and a combination thereof. [0029] In the present invention,

In addition, the sensing electrode 200 may include various metals having excellent electrical conductivity. For example, the sensing electrode 200 may include a nanowire, a photosensitive nanowire film, a carbon nanotube (CNT), a graphene, or various metals.

In addition, the sensing electrode 200 may be disposed in a mesh shape including a metal. For example, the sensing electrode 200 may include Cu, Au, Ag, Al, Ti, Ni, or an alloy thereof. At this time, the mesh shape can be formed at random to prevent moire phenomenon. Moire phenomenon is a pattern caused by superimposing periodic stripes. It is a phenomenon in which neighboring stripes are overlapped and the thickness of the stripes becomes thicker than other stripes. Therefore, in order to prevent such a moire phenomenon, the conductive pattern shape may be variously arranged.

Specifically, the conductive pattern may include an opening portion and a front portion. At this time, the line width of the conductive pattern line portion may be 0.1 μm to 10 μm. Conductive pattern line portions having a line width of 0.1 mu m or less may not be possible in the manufacturing process. When the line width is 10 탆 or less, the pattern of the sensing electrode 200 can be made invisible. Preferably, the line width of the conductive pattern line portion may be 0.5 탆 to 7 탆. More preferably, the line width of the conductive pattern line portion may be 1 탆 to 3.5 탆.

In addition, the opening portion of the conductive pattern may be arranged in various shapes such as a rectangular shape, a diamond shape, a pentagon, a hexagonal polygonal shape, or a circular shape. That is, the conductive pattern may have a regular shape.

However, the embodiment is not limited thereto, and the conductive pattern may have an irregular shape. That is, the conductive pattern openings may be variously provided in one conductive pattern.

When the sensing electrode 200 has a mesh shape, the sensing electrode 200 may be made of a metallic material so that the sensing electrode 200 is not seen. In addition, the resistance of the sensing electrode 200 can be reduced, and the present invention can be applied to the substrates 101 and 102 of a large size. Further, when the substrates 101 and 102 are bent, the sensing electrode 200 can be bent without being physically damaged. Accordingly, the present invention can be applied to a touch window having a large area, and a touch window can be applied to a flexible touch device or a curved touch device. In addition, the bending characteristics and reliability of the touch window can be improved.

In addition, the sensing electrode 200 may include a conductive polymer. When the sensing electrode 200 is formed of a conductive polymer, a transparent pattern can be formed. In addition, the sensing electrode 200 formed of a conductive polymer has flexibility and can be applied to a flexible touch device or a curved touch device. In addition, the conductive polymer can form a light weight touch device with a low density material.

Although not shown in the drawing, an index matching layer may be further formed on the back surface of the cover substrate 400, the first substrate 101, or the second substrate 102.

3 to 5, a method of forming a touch window according to an embodiment is as follows. 3, a resin layer 12 disposed between the lower release film 11 and the upper release film 13 is provided. The lower release film 11 can support the resin layer 12 and the upper release film 13 can secure the flatness of the resin layer 12. [ That is, when the resin layer 12 can have a sufficient flatness, the upper release film 13 may be omitted.

At this time, the resin layer 12 may be formed of a photocurable resin. Preferably, the resin layer 12 may be formed of a resin which is cured by UV irradiation. The photocurable resin can shorten the curing time.

Referring to FIG. 4, the upper release film 13 is removed, and the sensing electrode 200 is formed on the upper surface of the resin layer 12. The sensing electrode 200 may be a first sensing electrode or a second sensing electrode. That is, the sensing electrode 200 may extend in one direction.

Since the lower release film 11 supports the resin layer 12, the sensing electrode 200 can be stably formed. That is, in the absence of the lower release film 11, the resin layer 12 is not supported, and the pattern implementation of the sensing electrode 200 formed on the resin layer 12 may fail.

Referring to FIG. 5, the lower release film 11 may be removed after the sensing electrode 200 is formed. Accordingly, the resin layer 12 may be the first substrate 101 or the second substrate 102. That is, at least one substrate of the first substrate 101 and the second substrate 102 may be formed of the resin layer 12.

The second substrate 102 on which the second sensing electrode 220 is formed may be disposed on the first substrate 102 on which the first sensing electrode 210 is formed. In addition, a cover substrate 400 may be disposed on the second substrate 102. The first substrate 101 and the second substrate 102 may be bonded together with an adhesive layer therebetween. In addition, the second substrate 102 and the cover substrate 400 may be bonded together with an adhesive layer therebetween. The adhesive layer may include an optical transparent adhesive (OCA) or an optical transparent resin (OCR).

In the drawing, the lower release film 11 is shown to be separated before the bonding step, but the present invention is not limited thereto. For example, the lower release film 11 may be detached from the second substrate 102 after the cover substrate 400 and the second substrate 102 are bonded together through the adhesive layer. The lower release film 11 may be detached from the first substrate 101 after the second substrate 102 and the first substrate 101 are bonded together through an adhesive layer.

Therefore, even if the cover substrate 400 is damaged or damaged, the touch window according to the embodiment can realize touching and driving, and can reduce the thickness. In the case of the conventional PET substrate, when the thickness is 50 μm or less, it is difficult to form the electrode pattern, but the substrate of the touch window according to the embodiment can be lowered to 50 μm or less.

Further, the cover substrate 400 can be prevented from being weakened, the rigidity of the cover substrate 400 can be secured, and scattering can be prevented. In addition, the flexibility of the substrate formed of resin can be secured, and the flexible, curved, or bendable characteristics of the touch window according to the embodiment can be improved.

Next, a touch window according to the second embodiment will be described with reference to FIGS. 6 and 7. FIG. 6 is an exploded perspective view of a touch window according to the second embodiment. 7 is a cross-sectional view of a touch window according to the second embodiment. The description overlapping with the embodiment described above may be omitted. The same reference numerals are assigned to the same components.

A sensing electrode 200 is formed on the effective area AA of the substrate 103 and a wiring 300 is formed on the non-effective area UA of the substrate 103. The wiring 300 may apply an electrical signal to the sensing electrode 200 and may be formed in the ineffective area UA to be invisible. A circuit board or the like connected to the wiring 300 may be located in the ineffective area UA.

The sensing electrode 200 may include a first sensing electrode 210, a second sensing electrode 220, and a bridge electrode 230. The first sensing electrode 210, the second sensing electrode 220, and the bridge electrode 230 may include the same material or may include different materials. The first sensing electrode 210, the second sensing electrode 220, and the bridge electrode 230 may be disposed on the same surface of the substrate 103.

Although the first sensing electrode 210, the second sensing electrode 220 and the bridge electrode 230 are formed on the upper surface of the substrate 103 in the drawing, the present invention is not limited thereto, The sensing electrode 210, the second sensing electrode 220, and the bridge electrode 230 may be formed on the back surface of the substrate 103.

The first sensing electrode 210 may extend in a first direction on the effective region AA and the second sensing electrode 220 may extend in a second direction that is different from the first direction . In this case, the first direction and the second direction may be perpendicular to each other.

The first sensing electrode 210 may be connected to the first wiring 310 formed in the non-effective region UA. Also, the second sensing electrode 220 may be connected to the second wiring 220 formed in the ineffective area UA.

The first sensing electrode 210 may include a plurality of first electrode units and a connection unit. The plurality of first electrode units may be arranged to extend in the first direction. At this time, the plurality of first electrode units may be electrically connected through the connection unit.

The second sensing electrode 220 may include a plurality of second electrode units. The plurality of second electrode units may be arranged to extend in the second direction. The plurality of second electrode units may be electrically connected through the bridge electrode 230.

The bridge electrode 230 is disposed on the insulating layer 600. The insulating layer 600 is formed to expose the second sensing electrode 220. The bridge electrode 230 may be connected to the second sensing electrode 230 exposed by the insulating layer 600. That is, the bridge electrode 230 may be arranged to connect the second electrode part of the second sensing electrode 220 formed in a spaced apart relation in the second direction. Also, the bridge electrode 230 may be disposed to connect the second sensing electrode 220 and the second wiring 320 to each other.

The bridge electrodes 230 may be arranged in a bar shape, for example. In detail, the bridge electrodes 230 may be arranged in a bar shape spaced apart at regular intervals on the effective area AA. However, the shape of the bridge electrode 230 is not limited thereto, and it is sufficient that the bridge electrode 230 can connect the second electrode portion of the second sensing electrode 220, which are adjacent to each other in the second direction.

The insulating layer 600 may be disposed on the first sensing electrode 210 to expose the second sensing electrode 220. That is, it is sufficient that the shape of the insulating layer 600 exposes the second sensing electrode 220 and the exposed second sensing electrode 220 and the bridge electrode 230 can be connected.

The cover substrate 400 is disposed on the substrate 103 on which the sensing electrode 200 and the wiring 300 are formed. That is, the cover substrate 400 may be disposed on the substrate 103 on which the first sensing electrode 210, the second sensing electrode 220, the insulating layer 600, and the bridge electrode 230 are formed.

An adhesive layer 63 may be formed between the substrate 103 and the cover substrate 400. For example, the adhesive layer 63 may include an optical transparent adhesive (OCA) or an optical transparent resin (OCR).

Although not shown in the drawing, an index matching layer may be further formed on the back surface of the cover substrate 400 or the substrate 103.

The substrate 103 may support the sensing electrode 200, the wiring 300, and the circuit substrate formed thereon. The substrate 103 may be formed of a resin. In detail, the substrate 103 may be formed of a photocurable resin.

The substrate 103 formed of the resin may be formed to have a thinner thickness than a plastic substrate such as polyethylene terephthalate (PET). For example, the substrate 103 may be formed to a thickness of 0.5 to 50 탆. Preferably, the substrate 103 may be formed to a thickness of 0.5 to 20 탆. More preferably, the substrate 103 may be formed to a thickness of 1 to 10 mu m. Accordingly, the thickness of the touch window including the substrate 103 formed of the resin can also be reduced.

Further, the resin is a material having elasticity and flexibility, and the substrate 103 may have flexibility. In addition, when the substrate 103 formed of the resin is disposed below the cover substrate 400, the rigidity of the touch window can be increased.

The substrate 103 can be formed by forming a resin layer on a release film, forming a sensing electrode 200 on the resin layer, and separating the release film. That is, after the first sensing electrode 210, the second sensing electrode 220, the insulating layer 600, and the bridge electrode 230 are formed on the resin layer formed on the release film, the release film is separated from the resin layer , And the resin layer may be the substrate 103. However, the present invention is not limited thereto, and the release film may be separated after the cover substrate 400 and the substrate 103 are bonded.

When the sensing electrode 200 and the wiring 300 are formed directly on the rear surface of the cover substrate 400, the strength of the cover substrate 400 is lowered and the overall strength of the touch window is lowered, Could be lowered. Further, it is difficult to drive the sensing electrode 200 and the wiring 300 when the cover substrate 400 is broken.

Therefore, in the touch window according to the embodiment, the sensing electrode 200 and the wiring 300 are formed on the substrate 103. That is, the cover substrate 400 is prevented from being damaged in the process of forming the sensing electrode 200 and the wiring 300, and the strength is prevented from being weakened. Accordingly, it is possible to provide the scattering prevention characteristics of the cover substrate 400, to secure rigidity, and the touch window according to the embodiment can have improved reliability. That is, even if the cover substrate 400 is broken or damaged, touch implementation and driving can be performed.

Next, a touch window according to the third embodiment will be described with reference to FIG. 8 is a cross-sectional view of a touch window according to the third embodiment. The description overlapping with the above-described embodiments may be omitted. The same reference numerals are assigned to the same components.

In addition, an insulating layer 610 is disposed between the first sensing electrode 210 and the second sensing electrode 220, a separate substrate may be omitted, and a transparent adhesive for optical use (OCA) may be omitted.

For example, for example, the substrate 103 may be formed to a thickness of 0.5 to 50 탆. Preferably, the substrate 103 may be formed to a thickness of 0.5 to 20 탆. More preferably, the substrate 103 may be formed to a thickness of 1 to 10 mu m. Accordingly, the thickness of the touch window including the substrate 103 formed of the resin can also be reduced.

Further, the resin is a material having elasticity and flexibility, and the substrate 103 may have flexibility. In addition, when the substrate 103 formed of the resin is disposed below the cover substrate 400, the rigidity of the touch window can be increased.

Also, since the first sensing electrode 210 and the second sensing electrode 220 are formed on one surface of the same substrate and a separate insulating layer or a bridge electrode may be omitted, the thickness of the touch window may be reduced.

The cover substrate 400 may be disposed on the substrate 104 on which the sensing electrode 200 and the wiring 300 are formed. An adhesive layer 65 may be formed between the substrate 104 and the cover substrate 400.
