The present invention relates to a method for manufacturing a touch panel sensor and a touch panel sensor, and more particularly to a method for manufacturing a touch panel sensor and a touch panel sensor capable of both preventing bone appearance and preventing moire.

Display devices equipped with a touch panel that inputs information by bringing a user's finger or pen into contact with the display screen are used in mobile electronic devices such as portable terminals, various home appliances, automatic teller machines, etc. Yes.

Patent Document 1 uses a straight conductive thin wire as the conductive thin wire constituting the transparent conductive film. Since the electrical resistance of the conductive thin wire is proportional to the length, considering the conductivity of the transparent conductive film, it is not possible to use a straight line connecting the one end to the other end of the conductive thin wire, that is, a straight conductive thin wire. It is advantageous.

However, when the present inventor researched the use of a straight conductive thin wire as the conductive thin wire constituting the transparent conductive film as the X electrode and the Y electrode of the touch panel sensor, from the viewpoint of preventing bone appearance and moire. There is room for further improvement.

Bone appearance means that streaks derived from the conductive thin wires constituting the X electrode and the Y electrode are visually recognized. Bone appearance may occur due to optical interference between the conductive thin wires constituting the X electrode and the Y electrode, even when the conductive thin wires themselves have a thinness that is difficult to visually recognize.

Moire is a streak resulting from the combination of conductive thin wires constituting the X and Y electrodes and other elements in the device when a transparent substrate provided with X and Y electrodes is incorporated into the device. Is to be visually recognized. Moire can be caused by, for example, optical interference between the conductive thin wires forming the X electrode and the Y electrode and the pixel array included in the image display element in the device.

Preventing bone appearance and moire brings about an effect such that, for example, when an image display element is disposed on the back surface of the touch panel sensor, the image on the back surface can be recognized more clearly.

Therefore, an object of the present invention is to provide a method for manufacturing a touch panel sensor and a touch panel sensor that can achieve both bone-blocking prevention and moire prevention.

Hereinafter, embodiments for carrying out the present invention will be described in detail.

In the method for manufacturing a touch panel sensor of the present invention, an X electrode composed of conductive thin wires is formed on one surface of a transparent substrate, and a Y electrode composed of conductive thin wires is formed on the other surface of the transparent substrate. . As such a conductive thin wire, a line-shaped liquid is applied to the transparent base material by an ink jet method using an ink containing a conductive material, and as the line-shaped liquid is dried, the conductive material in the ink is removed. The non-linear conductive thin wire is formed by selectively depositing on both edges of the line liquid. Thereby, the effect which can manufacture the touchscreen sensor which can achieve both bone-viewing prevention property and moire prevention property is acquired.

The non-linear conductive thin wire includes an inclined line element that is inclined with respect to the direction connecting the one end to the other end of the non-linear conductive thin wire in the shortest distance. The inclined line element can be constituted by a straight line or a curved line. Further, by combining a plurality of inclined line elements, for example, an element such as a zigzag element or a wavy line element that repeatedly meanders to the left and right with respect to the longitudinal direction of the conductive thin line can be configured.

Hereinafter, a case where the non-linear conductive thin wire is formed of a zigzag-like element in the first embodiment and a case where the non-linear conductive thin wire is formed of a wavy-line element will be described in the second embodiment.

[First aspect]
First, an example of a touch panel sensor obtained by the method for manufacturing a touch panel sensor according to the first aspect will be described with reference to FIG.

The touch panel sensor has a plurality of strip-shaped X electrodes 2 arranged in parallel in the X-axis direction at a predetermined interval on one surface of a sheet-like transparent substrate 1, and a strip-shaped Y electrode 3 on the other surface at a predetermined interval in the Y-axis. A plurality are arranged in parallel in the direction.

The X-axis direction and the Y-axis direction are in a crossing relationship with each other. The X electrode 2 and the Y electrode 3 intersect each other with an interval corresponding to the thickness of the transparent substrate 1. The X electrode 2 and the Y electrode 3 are insulated from each other by the transparent substrate 1.

These X electrode 2 and Y electrode 3 can be connected to a control circuit, respectively, and can be suitably used as, for example, a capacitive touch panel sensor. In the case of a capacitive touch panel, during operation, an induced current based on a change in capacitance that occurs when a user's finger or conductor approaches or comes into contact with the X electrode 2 and the Y electrode 3 is used. The position coordinates of a finger or a conductor can be detected.

One X electrode 2 is composed of an assembly of conductive thin wires 21. A plurality of conductive thin wires 21 constituting one X electrode 2 are connected to a control circuit (not shown) via a collecting wire 22. One Y electrode 3 is also constituted by an assembly of conductive thin wires 31. A plurality of conductive thin wires 31 constituting one Y electrode 3 are connected to a control circuit (not shown) via a collector line 32.

The conductive thin wires 21 and 31 included in the X electrode 2 and the Y electrode 3 are respectively formed into the line shape as the line liquid containing the conductive material applied to the transparent substrate 1 is dried. It is composed of non-linear conductive thin wires formed by selectively depositing on both edges of the liquid. In this embodiment, the non-linear conductive thin wire is composed of a zigzag element.

The non-linear conductive thin wire 21 constituting the X electrode 2 is formed in the forming direction of the non-linear conductive thin wire 21 as a whole (or the direction connecting the one end to the other end of the non-linear conductive thin wire 21 in the shortest direction. ) Are formed along the longitudinal direction of the X electrode 2. Similarly, the non-linear conductive thin wire 31 constituting the Y electrode 3 is formed in the shortest direction from one end to the other end of the non-linear conductive thin wire 31 as a whole (or from one end to the other end of the non-linear conductive thin wire 31). Is formed along the longitudinal direction of the Y electrode 3.

The manufacturing method of the touch panel sensor will be described in detail with reference to FIG. In addition, although the following description demonstrates the electroconductive fine wire 21 which mainly comprises the X electrode 2, the electroconductive fine wire 31 which comprises a Y electrode can also be used.

First, as shown in FIG. 2A, a plurality of line-like liquids 4 containing a conductive material are applied on the transparent substrate 1. In this embodiment, the line-like liquid 4 is applied in a zigzag shape.

Next, as the line-shaped liquid 4 is dried, a conductive material is selectively deposited on both edges of the line-shaped liquid 4 by the coffee stain phenomenon, so that the line-shaped liquid 4 can be removed from the line-shaped liquid 4 as shown in FIG. A thin wire pair 23 composed of a pair of conductive thin wires 21 and 21 as shown in FIG.

That is, since the drying of the line-shaped liquid 4 applied on the transparent substrate 1 is faster at the edge than at the center, first, a local deposition of a conductive material occurs at the edge. The edge of the liquid is fixed by the deposited conductive material, and the shrinkage in the width direction of the line-shaped liquid 4 accompanying the subsequent drying is suppressed. In the line-shaped liquid 4, a flow from the center to the edge is formed so as to supplement the liquid lost by evaporation at the edge. Due to this flow, further conductive material is carried to the edge and deposited, and a pair of conductive thin wires 21 and 21 are formed on both edges of the single line-like liquid 4.

It is preferable to promote the formation of a flow that carries the conductive material to the edge. For example, by adjusting conditions such as solids concentration, contact angle between liquid and substrate, amount of liquid, substrate heating temperature, liquid arrangement density, or environmental factors such as temperature, humidity, and pressure, the edge of the liquid Can be fixed at an early stage, and the difference in evaporation amount between the liquid central portion and the edge can be increased. This can facilitate the formation of a flow that carries the conductive material to the edge.

The application of the line-like liquid 4 on the transparent substrate 1 can be performed by an ink jet method. Specifically, while moving an inkjet head provided in a droplet ejection device (not shown) relative to the substrate, ink containing a conductive material is ejected from the nozzle of the inkjet head, and the ejected ink droplet is placed on the substrate. , The line-shaped liquid 4 having a desired shape can be applied. The droplet discharge method of the inkjet head is not particularly limited, and for example, a piezo method or a thermal method can be used.

In this embodiment, the plurality of conductive thin wires 21 constituting the X electrode 2 are arranged side by side without crossing each other, and the plurality of conductive thin wires 31 constituting the Y electrode 3 are also spaced without crossing each other. Are placed side by side. With such an arrangement, for example, the aperture ratio (the ratio of the region where the conductive fine lines are not formed) can be increased as compared with the electrode formed by intersecting the conductive thin lines in a lattice shape. Since it is excellent in performance, it has the effect of preventing the appearance of bones. Further, from the viewpoint of the resistance value, the conductive thin wire formed by using the coffee stain phenomenon is less likely to cause disconnection, so that variation in resistance between terminals can be reduced.

The zigzag element preferably has a zigzag meandering width smaller than a 1/2 cycle length of the zigzag. In FIG. 3, α is a half cycle length of the zigzag, and is half the length of one cycle connecting the peaks and peaks or the valleys and valleys of the zigzag along the entire zigzag formation direction. . β is the zigzag meandering width, and is the zigzag meandering width in a direction perpendicular to the forming direction of the zigzag as a whole. When the zigzag meandering width β is smaller than the zigzag ½ period length α, it is possible to reduce the resistance of the resulting pattern and to further prevent the appearance of bone. This effect is more prominent when the α / β ratio is in the range of 1.1 to 4.

In addition, the zigzag ½ period length α is preferably in the range of 100 μm to 2 mm, and more preferably in the range of 100 to 500 μm. On the other hand, the meandering width β of the zigzag is preferably in the range of 100 μm to 1 mm, and more preferably in the range of 100 to 500 μm. When α and / or β are within these ranges, the above relationship of α> β is satisfied, and preferably the ratio of α / β is in the range of 1.1 to 4, thereby reducing the resistance of the pattern. The effect of preventing the appearance of bones is more remarkable.

The fine wire interval γ when a plurality of conductive thin wires 21 made of zigzag elements are arranged side by side is not particularly limited, but α / γ is preferably 3 or more in relation to the zigzag ½ period length α. Thereby, the effect of the present invention is more remarkably exhibited. α / γ is particularly preferably 3 or more and less than 20. Here, the thin wire interval γ is a space between the conductive thin wires 21 in a direction orthogonal to the forming direction of the entire zigzag.

[Second embodiment]
Next, a 2nd aspect is demonstrated. In the second embodiment, as shown in FIG. 4, a touch panel sensor is manufactured in which the conductive thin wires 21 and 31 included in the X electrode 2 and the Y electrode 3 are composed of non-linear conductive thin wires made of wavy elements. . The non-linear conductive thin wires 21 and 31 made of a wavy element can be formed by applying the line-like liquid described in the first embodiment in a wavy line.

The conductive thin wires 21 and 31 having the wavy element are rounded and meandering. As the wavy element, a curved line like a sine wave or a combination of a straight line and a curved line like a wavy line with rounded corners of a zigzag can be preferably used.

It is preferable that the wavy element has a wavy line meandering width smaller than a half cycle length of the wavy line. In FIG. 5, α ′ is a half cycle length of the wavy line, and is half the length of one cycle connecting the peaks and peaks of the wavy lines or the valleys and valleys along the forming direction of the entire wavy line. is there. β ′ is the meandering width of the wavy line, and is the width of the meandering of the wavy line in the direction perpendicular to the forming direction of the entire wavy line. Since the meandering width β ′ of the wavy line is smaller than the half period length α ′ of the wavy line, the resistance of the obtained pattern can be reduced, and the effect of further preventing the appearance of bone can be obtained. This effect is more prominent when the α ′ / β ′ ratio is in the range of 1.1 to 4.

Further, the half cycle length α ′ of the wavy line is preferably in the range of 100 μm to 2 mm, and more preferably in the range of 100 to 500 μm. On the other hand, the meandering width β ′ of the wavy line is preferably in the range of 100 μm to 1 mm, and more preferably in the range of 100 to 500 μm. When α ′ and / or β ′ are within these ranges, the above-described relationship of α ′> β ′ is satisfied, and preferably the ratio of α ′ / β ′ is in the range of 1.1 to 4, The effect of lowering the resistance of the pattern and preventing the appearance of bone is more remarkable.

There is no particular limitation on the fine wire interval γ ′ when a plurality of conductive thin wires 21 made of wavy elements are juxtaposed, but α ′ / γ ′ is 3 or more in relation to the half period length α ′ of the wavy wire. It is preferable. Thereby, the effect of the present invention is more remarkably exhibited. α ′ / γ ′ is particularly preferably 3 or more and less than 20. Here, the thin wire interval γ ′ is a space between the conductive thin wires 21 in a direction orthogonal to the forming direction of the entire wavy line.

As described above, as the non-linear conductive thin wire, the first embodiment is exemplified by the zigzag-like element, and the second embodiment is constituted by the wavy-line element. However, the non-linear conductive thin wire is constituted by the zig-zag-like element. Is particularly preferred. When forming a zigzag with a line-shaped liquid using an inkjet method, it can form more smoothly compared with the case where a wavy line is formed. As a result, the non-linear conductive thin wire composed of zigzag-shaped elements formed from zigzag line-shaped liquid is compared with the non-linear conductive thin wire composed of wavy-line elements formed from wavy line-shaped liquid. And become more stable. Therefore, when the non-linear conductive thin wire is formed of zigzag-like elements, the effect of reducing the resistance of the pattern, preventing the appearance of bones, and preventing moire becomes remarkable.

[Other aspects]
The shape of the non-linear conductive thin wire may or may not have regularity. Hereinafter, the regularity and irregularity of the shape of the non-linear conductive thin wire will be described with reference to FIGS. 6 (a) to (c).

In the example shown in FIG. 6A, the zigzag elements in one conductive thin wire 21 have regularity, and the zigzag elements in the plurality of conductive thin wires 21 also have regularity. That is, in one conductive thin wire 21, the zigzag half cycle length α and the zigzag meandering width β are kept constant. This regularity is maintained in common between the adjacent conductive thin wires 21. That is, the adjacent conductive thin wires 21 have shapes that can be overlapped with each other by parallel movement. The interval between adjacent conductive thin wires 21 is constant.

In the example shown in FIG. 6B, the zigzag element in one conductive thin wire 21 does not have regularity, but the zigzag element between the plurality of conductive thin wires 21 has regularity. That is, in one conductive thin wire 21, the zigzag meandering width is constant, but the zigzag ½ period length varies and is irregular. On the other hand, when viewed between adjacent conductive thin wires 21, this irregularity is maintained in common and has regularity. That is, the adjacent conductive thin wires 21 have shapes that can be overlapped with each other by parallel movement. The interval between adjacent conductive thin wires 21 is constant.

In the example shown in FIG. 6C, the zigzag element in one conductive thin wire 21 does not have regularity, and the zigzag element in the plurality of conductive thin wires 21 does not have regularity. . That is, in one conductive thin wire 21, the zigzag meandering width is constant, but the zigzag ½ period length varies and is irregular. On the other hand, there is regularity between adjacent pairs of conductive thin wires 21 formed from one line-shaped liquid between adjacent conductive thin wires 21, but conductivity formed from other line-shaped liquids. There is no regularity with respect to the thin wire 21. That is, the adjacent conductive fine wires 21 and 21 have a shape that cannot be overlapped with each other by parallel movement. The spacing between adjacent conductive thin wires 21 is not uniform. In addition, when the space | interval between adjacent electroconductive thin wires 21 and 21 becomes non-uniform | heterogenous like the example of FIG.6 (c), the above-mentioned thin wire | line space | interval γ is in the direction orthogonal to the formation direction as the whole zigzag line. A value at a portion where the interval between the conductive thin wires 21 is the smallest is taken.

The examples of FIGS. 6A to 6C are all preferable, but from the viewpoint of further improving the moire prevention, the example of FIG. 6C is the best, and then FIG. 6B. This is the order of the example of FIG. 6A. In other words, the more the conductive thin wires are irregular, the easier it is to obtain moiré prevention.

On the other hand, in order to form each conductive thin wire 21 more stably, it is preferable to have regularity between adjacent conductive thin wires 21. That is, having regularity between adjacent conductive thin wires 21 also means having regularity between adjacent line-like liquids provided on the transparent substrate 1 in order to form these. When drying a plurality of adjacent line-shaped liquids, it is susceptible to substrate temperature fluctuations and vapors accompanying the drying of adjacent line-shaped liquids, but by having regularity between adjacent line-shaped liquids, The interval between the line-shaped liquids is constant, the above-described influence can be homogenized over the plurality of line-shaped liquids, and each conductive thin wire 21 can be formed more stably. Here, the regularity has been described by giving an example of a zigzag element, but it can also be used in the case of a wavy element.

It is preferable to impart irregularity within a range in which the conductive thin wire maintains the zigzag element or the wavy element. At this time, the meandering width may be varied, but it is preferable that the meandering width is constant and the ½ period length is varied to impart irregularity. Furthermore, it is also preferable to provide irregularity within the range of preferable conditions described for α and β (or α ′ and β ′).

In the above description, the case where the shape of the conductive thin wires 21 and 31 is the same between the X electrode 2 and the Y electrode 3 has been mainly shown, but it is also preferable to make them different. For example, since the Y electrode 3 is arranged via the transparent base material 1 with respect to the X electrode 2 provided on the user side during use, the visibility of the X electrode 2 is caused by, for example, a difference in optical path length. Tends to be higher than the visibility of the Y electrode 3. Therefore, it is preferable to make the shapes of the conductive thin wires 21 and 31 different between the X electrode 2 and the Y electrode 3 so as to reduce the difference in visibility. As an example in the case where the shapes of the conductive thin wires 21 and 31 are different between the X electrode 2 and the Y electrode 3, inclined line elements such as zigzag elements and wavy line elements are made different, the meandering width and / or 1/2 The cycle length can be varied.

For example, zigzag elements or wavy elements are added to the conductive thin wires 21 and 31 constituting the X electrode 2 and the Y electrode 3, and the 1/2 cycle length of the conductive thin wires 21 constituting the X electrode 2 is It is preferable that the conductive fine wire 31 constituting the Y electrode 3 is formed so as to be longer than a half cycle length. Thereby, since the area occupied by the formation region of the conductive thin wire 21 constituting the X electrode 2 is smaller than that of the conductive thin wire 31 constituting the Y electrode 3, the visibility of the X electrode 2 is lowered and the Y electrode is reduced. 3 visibility can be approached. From the same point of view, it is preferable that the meandering width of the conductive fine wire 21 constituting the X electrode 2 is smaller than the meandering width of the conductive fine wire 31 constituting the Y electrode 3.

In addition, since the conductive thin wire 21 constituting the X electrode 2 is more easily recognized by the edge than the conductive thin wire 31 constituting the Y electrode 3, a wavy element is provided on the conductive thin wire 21 constituting the X electrode 2. It is also preferable to provide a zigzag element to the conductive thin wire 31 constituting the Y electrode 3 to reduce the difference in edge visibility.

As shown in FIG. 7, it is preferable that at least a part between the conductive thin wires 21 is connected by a conductive bridge wire 24 in one X electrode 2. Here, the conductive thin wire 21 constituting the X electrode 2 will be described, but this description can also be applied to the conductive thin wire 31 constituting the Y electrode 3.

By connecting the conductive thin wires 21 constituting one X electrode 2 with the conductive bridging wire 24, the conductivity of the X electrode 2 can be ensured more reliably, and the detection sensitivity of the touch panel sensor can be further improved.

The method for forming the conductive cross-linking line 24 is not particularly limited, but after forming the conductive thin line 21, the ink containing the conductive material is formed in dots or lines by, for example, an inkjet method so as to straddle the plurality of conductive thin lines 21. It is preferable to form it by giving it to the shape and drying it. Furthermore, it is particularly preferable to form the conductive cross-linked line 24 formed by the coffee stain phenomenon from the viewpoint of preventing the conductive cross-linked line 24 from being visually recognized. In the illustrated example, a pair of conductive thin wires formed by the coffee stain phenomenon is used as the conductive bridging wires 24 and 24.

In the illustrated example, one conductive bridge line 24 connects two adjacent conductive thin lines 21 and 21, but three or more conductive thin lines are connected by one conductive bridge line. You may connect between.

Further, in the illustrated example, a plurality of conductive thin wires constituting one X electrode 2 are electrically connected to each other at the other end opposite to one end of the conductive thin wires 21 connected to the collector line 22. A membrane 25 is provided. Thereby, the conductivity of the X electrode 2 can be ensured more reliably. The conductive film 25 is preferably disposed outside the image display frame when the touch panel sensor is incorporated into the device.

It is preferable that the conductive thin wires 21 and 31 constituting one or both of the X electrode 2 and the Y electrode 3 include a metal film formed by plating.

The plating method is not particularly limited, but electroless plating and electrolytic plating can be preferably exemplified, and electrolytic plating is particularly preferable. Suitable electroplating can be performed using the conductivity of the conductive thin wire.

Although the plating metal is not particularly limited, for example, silver, copper, nickel and the like can be preferably exemplified. It is also preferable to apply a plurality of plating processes with different plating metals to the conductive thin wires. That is, it is preferable to laminate a plurality of metal layers on the conductive thin wire. For example, a conductive thin wire made of silver is first subjected to electrolytic copper plating to form a copper film, and then subjected to electrolytic nickel plating to form a nickel layer, so that the conductive thin wire has high conductivity and durability. Can be granted.

In the above description, the case where the non-linear conductive thin wire is mainly composed of the zigzag element or the wavy line element has been mainly shown, but the present invention is not limited to this, and the other end of the non-linear conductive thin wire is changed to the other. Any material can be preferably used as long as it is composed of inclined line elements that are inclined with respect to the direction connecting the ends to the shortest. As described above, the inclined line element can be constituted by a straight line or a curved line. Further, by combining a plurality of inclined line elements, for example, an element that repeatedly meanders to the left and right with respect to the longitudinal direction of the conductive thin line, such as a zigzag element or a wavy line element, can be configured.

From the viewpoint of preventing moire, it is preferable that the ratio of the length of the inclined line element to the length of the line constituting one non-linear conductive thin wire is larger, preferably 50% or more, more preferably 80% or more. , Most preferably 100% is constituted by inclined line elements.

As in the examples of the zigzag element and the wavy element illustrated above, the non-linear conductive fine wire constituting the X electrode is formed in the formation direction of the non-linear conductive thin wire (or the non-linear conductive wire). The direction in which the other end of the thin thin wire is linearly connected to the other end is preferably formed along the longitudinal direction of the X electrode. At this time, the inclined line element included in the non-linear conductive thin wire is preferably inclined with respect to the longitudinal direction of the X electrode, and further inclined with respect to the longitudinal direction of the Y electrode. preferable. Thereby, the effect of preventing moire becomes remarkable.

Similarly, the non-linear conductive fine wire constituting the Y electrode is formed as the whole non-linear conductive thin wire (or the direction in which one end of the non-linear conductive thin wire is linearly connected).

Thereby, the effect of preventing moire becomes remarkable.

Further, the non-linear conductive thin wire slant line element constituting the X electrode and the non-linear thin conductive wire slant line element constituting the Y electrode may be formed in a direction crossing each other. preferable. Thereby, the effect of preventing the appearance of bone becomes remarkable.

It is sufficient that at least a part of the conductive thin wires constituting the X electrode and the Y electrode are non-linear conductive thin wires. However, the effect of the present invention is obtained when all the conductive thin wires are non-linear conductive thin wires. Becomes more prominent.

<Shape of fine wire pair>
FIG. 8 is a perspective view schematically showing a thin wire pair 23 composed of conductive thin wires 21 and 21 formed from one line-shaped liquid. In the following description, the conductive thin wire 21 constituting the X electrode 2 will be mainly described, but this description can also be applied to the conductive thin wire 31 constituting the Y electrode 3. FIG. 8 shows a part of the thin wire pair 23 of the non-linear conductive thin wires 21 and 21 and is merely shown in a straight line for convenience.

The range of the arrangement interval I of the conductive thin wires 21 and 21 is not particularly limited, and is preferably in the range of 10 μm to 1000 μm, more preferably in the range of 10 μm to 500 μm, and more preferably in the range of 10 μm to 300 μm. The following range is most preferable. In addition, the arrangement | positioning space | interval I of the electroconductive fine wires 21 and 21 is a distance between each largest protrusion part of the electroconductive thin wires 21 and 21, and is decided corresponding to the line | wire width of a line-shaped liquid. The arrangement interval I may be, for example, a large arrangement interval of 50 μm or more, 100 μm or more, 200 μm or more, 300 μm or more, 400 μm or more, 500 μm or more, or even 1 mm or more. Although the upper limit of the arrangement | positioning space | interval I is not specifically limited, It is preferable that it is 5 mm or less, and it is preferable that it is 1 mm or less. In addition, by removing a part of the plurality of conductive thin wires 21 arranged in parallel, the conductive thin wires 21 may be arranged in parallel at an interval larger than the arrangement interval I of the thin wire pairs 23 formed by the coffee stain phenomenon. This is preferable.

The conductive fine wires 21 and 21 constituting the fine wire pair 23 do not necessarily have to be islands completely independent from each other. As shown in the drawing, the conductive thin wires 21 and 21 are connected by the thin film portion 20 formed between the conductive thin wires 21 and 21 at a height lower than the height of the conductive thin wires 21 and 21. It is also preferable that it is formed as a continuous body. From the viewpoint of further improving the thinning of the thin wire pair 23, the height Z of the thinnest portion where the thickness of the functional material is the thinnest between the conductive thin wires 21, 21, specifically, the thinnest portion of the thin film portion 20 The height Z is preferably in the range of 10 nm or less. Most preferably, in order to achieve a balance between transparency and stability, the thin film portion 20 is provided in the range of 0 <Z ≦ 10 nm.

The line widths W1 and W2 of the conductive thin wires 21 and 21 of the fine wire pair 23 are preferably 10 μm or less, respectively. If it is 10 micrometers or less, since it will be a level which cannot be visually recognized normally, it is more preferable from a viewpoint of improving transparency. Considering the stability of each conductive thin wire 21, 21, the width W1, W2 of each conductive thin wire 21, 21 is preferably in the range of 2 μm or more and 10 μm or less. The widths W1 and W2 of the thin conductive wires 21 and 21 are defined as Z, which is the height of the thinnest portion where the thickness of the functional material is the thinnest between the thin conductive wires 21 and 21. When the projecting heights of the conductive thin wires 21 and 21 are Y1 and Y2, the width of the conductive thin wires 21 and 21 at half the height of Y1 and Y2 is set. For example, when the thin wire pair 23 has the thin film portion 20 described above, the height of the thinnest portion in the thin film portion 20 can be set to Z. In addition, when the height of the thinnest part of the functional material between the conductive thin wires 21 and 21 is 0, the line widths W1 and W2 of the conductive thin wires 21 and 21 are conductive from the surface of the transparent substrate 1. The widths of the conductive thin wires 21 and 21 at half the heights H1 and H2 of the thin conductive wires 21 and 21 are used.

Since the line widths W1 and W2 of the conductive thin wires 21 and 21 constituting the thin wire pair 23 are extremely thin as described above, from the viewpoint of securing a cross-sectional area and reducing resistance, from the surface of the transparent substrate 1 It is desirable that the heights H1 and H2 of the conductive thin wires 21 and 21 be higher. Specifically, the heights H1 and H2 of the conductive thin wires 21 and 21 are preferably in the range of 50 nm to 5 μm. Furthermore, from the viewpoint of improving the stability of the thin wire pair 23, the H1 / W1 ratio and the H2 / W2 ratio are preferably in the range of 0.01 or more and 1 or less, respectively.

Furthermore, in order to further improve the thinning of the thin wire pair 23, the H1 / Z ratio and the H2 / Z ratio are each preferably 5 or more, more preferably 10 or more, and preferably 20 or more. Particularly preferred.

<Transparent substrate>
The transparent substrate 1 is not particularly limited, and examples thereof include glass and plastic. Among these, plastic is preferable. As the plastic, polyethylene terephthalate (abbreviated as PET), polybutylene terephthalate, polyethylene, polypropylene, acrylic, polyester, polyamide, polycarbonate, and the like are preferable.

Conventionally, a transparent conductive film made of an indium-tin composite oxide (ITO) formed by a sputtering method has been used as the X electrode and the Y electrode of the touch panel sensor. In order to obtain a film having high crystallinity. Since a high temperature treatment is required, the versatility of the base material is low, and it was particularly difficult to use plastic. On the other hand, the present invention has high versatility of the base material, and can form a transparent conductive film suitably for a base material made of plastic. Therefore, the touch panel sensor which has flexibility can be manufactured suitably using the flexibility of plastic. The touch panel sensor having flexibility can be used by being curved in accordance with a three-dimensional shape such as a three-dimensional structure, a human body, or an animal body. Moreover, since it can be rounded and made compact, it is advantageous for storage. Therefore, for example, it can be suitably used as a touch panel sensor mounted on a portable terminal, particularly a wearable terminal.

The transparent substrate 1 may have a single layer structure or a laminated structure. The layer structure of the transparent substrate 1 will be described with reference to FIG.

FIG. 9A shows an example in which the transparent substrate 1 has a single layer structure. In this case, the X electrode 2 is formed on one surface of the transparent substrate 1 and then the Y electrode 3 is formed on the other surface, or the Y electrode 3 is formed on one surface of the transparent substrate 1 and then the other surface. By forming the X electrode 2 on the touch panel sensor, a touch panel sensor is obtained. That is, a touch panel sensor in which the X electrode 2 and the Y electrode 3 are formed on both surfaces of a single transparent substrate is obtained.

FIG. 9B shows an example when the transparent substrate 2 has a laminated structure. Such a laminated structure is composed of two transparent substrates 11 and 11 and an adhesive film 12 disposed between the transparent substrates 11 and 11. In forming such a laminated structure, the X electrode 2 is formed on the first transparent base material 11 and the Y electrode 3 is formed on the second transparent base material 11. 2 A touch panel sensor is obtained by bonding the transparent base material 11 together. At the time of bonding, as shown in the drawing, it is preferable to bond them by interposing a transparent adhesive film 12 or the like.

When using a laminated structure, there is an advantage that it can be manufactured relatively easily as compared with a single-layer structure in which electrodes need to be formed on both sides of the same substrate. In both cases of using a single layer structure or a laminated structure, the use of non-linear conductive fine wires can prevent the appearance of bones appropriately. Therefore, it is necessary to precisely align the conductive thin wires between both surfaces. The effect that it can be manufactured easily is obtained.

In the above description, the configuration described for one aspect can be appropriately applied to other aspects.

Hereinafter, examples of the present invention will be described, but the present invention is not limited to the examples.

The pattern of the electroconductive fine wire formed in each film before bonding is shown in Fig.11 (a) and FIG.11 (b). The conductive pattern after pasting is shown in FIG. Here, the line width of the conductive thin wire is 5 μm, and the thin wire interval γ is 200 μm, which is the same as that of the sample 1.

Here, the line width of the conductive thin wire is 5 μm, and the thin wire interval γ is 200 μm, which is the same as that of the sample 1.

It is the total light transmittance (%) measured using “HAZEMETER (MODEL TC-HIIIDP)”. In addition, it corrected using the base material (film) without a pattern, and measured it as the total light transmittance of the created pattern.

(2) Bone visibility prevention 10 samples were prepared for each of samples 1 to 3, and the bone visibility prevention was evaluated according to the following evaluation criteria, and an average of 10 samples was obtained.
<Evaluation criteria>
5: Bone is not visible 4: Bone is slightly visible depending on the observation angle 3: Bone is slightly visible 2: Bone is visible 1: Bone is very visible In the above evaluation criteria, the larger the number, the more the bone is visible Good properties.

(3) Moire prevention property In the evaluation of the above “(2) Bone visibility prevention”, samples having a higher evaluation were selected from 10 samples prepared as samples 1 to 3, and three types of the samples were selected. The liquid crystal display (LCD) panel was stacked and the moire prevention property was evaluated according to the following evaluation criteria.
<Evaluation criteria>
5: No moiré occurs 4: Very little moiré occurs 3: Moire occurs in 1 to 2 types of panels 2: Moire occurs in all types of panels 1: Moire occurs in all types of panels In the above evaluation criteria, the larger the number, the better the moire prevention.

The results are shown in Table 1.

3. Evaluation From Table 1, the conductive thin wire constituting the conductive pattern dries the line-shaped liquid containing the conductive material applied to the transparent substrate, and the conductive material is placed on both edges of the line-shaped liquid. It can be seen that by comprising non-linear conductive fine wires formed by selective deposition, it is possible to suitably achieve both bone-viewing prevention and moire prevention.

(Example 2)
1. Fabrication of Touch Panel Sensor When forming a zigzag pattern with a line width of 5 μm and a fine line interval (γ) of 200 μm in the same manner as in Example 1, the zigzag half cycle length α and the zigzag meandering width β are as shown in Table 2. Samples 4 to 7 which were changed to were prepared.

2. Evaluation Method Samples 4 to 7 were evaluated for resistance between terminals, prevention of bone appearance, and prevention of moire. The results are shown in Table 2.

(1) Resistance between terminals The film on which the X electrodes before bonding in Samples 4 to 7 were formed was cut into a strip of 100 mm × 10 mm so that the long side was along the direction of forming the conductive thin wires, and the terminals (that is, The resistance value (Ω) at the both ends in the longitudinal direction of the strip-shaped region was measured. Prior to the measurement, the pattern is heated and fired by heating on a hot plate at 120 ° C. for 1 hour.

(2) Bone visibility prevention and moire prevention properties Bone visibility prevention and moire prevention were evaluated in the same manner as in Example 1.

The results are shown in Table 2. In Table 2, α is the zigzag ½ period length, β is the zigzag meandering width, and γ is the fine line interval.

3. Evaluation Table 2 shows that the zigzag meandering width β is smaller than the zigzag ½ period length α, so that the resistance between terminals can be reduced and the effect of preventing the appearance of bones is also increased.

(Example 3)
In the preparation of Sample 1 of Example 1, the regularity of the conductive thin wires was varied to obtain Samples 8 to 10 corresponding to FIGS. 6 (a) to 6 (c).

Sample 8 corresponds to FIG. 6 (a), has regularity in the zigzag-like element in one non-linear conductive thin wire, and between a plurality of non-linear conductive thin wires. Zigzag elements also have regularity.

The sample 9 corresponds to FIG. 6B, and the zigzag element in one non-linear conductive thin wire does not have regularity, but between a plurality of non-linear conductive thin wires. There is regularity in the zigzag-like element in.

The sample 10 corresponds to FIG. 6C, and the zigzag in one non-linear conductive thin wire does not have regularity, and the zigzag between a plurality of non-linear conductive thin wires. Has no regularity. Here, there is regularity between adjacent thin conductive wire pairs formed from one line-shaped liquid, and no regularity to conductive thin lines formed from other line-shaped liquids.

Sample 8 to 10 were evaluated for moiré prevention in the same manner as in Example 1. Sample 10 was the best, followed by Sample 9 and Sample 8. From this result, it can be seen that the more the non-linear conductive fine wires are irregular, the easier it is to obtain moiré prevention.

Further, when the resistance between the terminals of Samples 8 to 10 was evaluated in the same manner as in Example 2, no significant difference was observed, and all were good (low resistance).
