The conductive pattern 120 includes a first region 121 in the center and a second region 122 formed in the periphery of the first region 121. The first region 121 has a greater density of the conductors 125 in the same space than the second region 122.

The density of the conductors 125 in the first region 121 is greater than the density of the conductors 125 in the second region 122. For example, Big. That is, the amount of the carbon nanotube that the first region 121 fills the space is larger than the second region 122 in the same space.

The density of the conductor 125 can be calculated by converting the density of the three-dimensionally arranged conductor 125 onto a plane. Therefore, the space serving as a reference for determining the density of the conductor 125 may include a region where the conductor 125 is not disposed. For example, the first region 121 may be thicker than the second region 122 in terms of the thickness of the conductive film. In this case, even if the first region 121 has the same density as the first region 121 in a space having the same thickness as that of the second region 122, The second region 122 has a space in which the conductor 125 does not exist, and the density is diluted. Therefore, in this case, it is interpreted that the density of the first region 121 is greater than the density of the second region 122. [

When the carbon nanotube is filled in a specific space, the light transmittance is lower than when the carbon nanotube is not filled even if the diameter of the carbon nanotube is small and the light transmittance is high. Accordingly, the presence of the second region 122 allows the overall light transmittance of the conductive film to be lower than that of the case where the conductor 125 is filled to the width of the second region 122 at the same density as the first region 121 .

In addition, since the amount of the conductor 125 is reduced due to the second region 122 having a relatively low density, the cost is reduced.

On the other hand, the conductivity of the conductive pattern 120 is proportional to the number of contact points between the conductors 125, as long as the length of the conductor 125 is not equal to the length of the entire pattern. That is, as the conductors 125 cross each other more, the conductivity increases. The number of intersections of each conductor 125 is proportional to the length of the conductor 125 and the density of the conductor 125. If the length of the conductor 125 is determined, the number of intersections increases as the density of the conductor 125 increases, thereby increasing the conductivity. From this point of view, it can be expected that the first region 121 will have a higher conductivity than the second region 122. The conductivity of the second region 122 is lower than that of the first region 121 but the conductivity is lower than that of the first region 121 since the conductors 125 are distributed and the intersections therebetween are formed. Therefore, the presence of the second region 122 increases the conductivity of the entire conductive film compared to the case where the conductive pattern 125 is formed only in the width corresponding to the first region 121. [

When a voltage is applied to the first region 121, a charge flows along the conductor 125. When each conductor 125 intersects another conductor 125, charge is transferred to the other conductor 125 through this intersection. However, some of the roots may include an edge in the width direction of the first region 121, and if the second region 122 is not present, There is a case where the conductor does not intersect with the conductor 125 other than the conductor 125, and the transfer of the charge is stopped. If the second region 122 has a low density but a conductor 125 and forms an intersection with the conductor 125 at the edge portion of the first region 121, the transfer of charge can continue without stopping have. In this way, the second region 122 can also function to increase the conductivity with respect to the voltage applied to the first region 121.

In addition, the second region 122 can differentiate the charge transfer function of the entire conductive pattern 120. For example, when a first voltage is applied to the first region 121 of the conductive pattern 120, the first region 121 carries a first current. On the other hand, when the same first voltage is applied to the second region 122 of the conductive pattern 120, since the second region 122 has a resistance higher than that of the first region 121, Current. When a significantly low voltage is applied, it may carry current in the first region 121 but not in the second region 122 due to a relatively high resistance. In other words, different electric currents can be supplied for each region of the conductive pattern 120, and various information can be collected accordingly.

In some other embodiments of the present invention, as the conductors 125 that make up the second region 122 move closer to the periphery, the density of the conductors 125 relative to the space becomes smaller. That is, the farther from the boundary between the second region 122 and the first region 121, the higher the light transmittance can be. In some embodiments, the thickness of the second region 122 may be smaller as it is away from the first region 121.

The conductive pattern 120 may be embodied as a plurality of stripe patterns extending in parallel in one direction on a flatness degree, as shown in Fig. At this time, the width of each stripe pattern may be 50 탆 to 10,000 탆. The width of the first region other than the second region may be 10 탆 to 5,000 탆. The spacing between neighboring stripe patterns may be between 50 μm and 10,000 μm. In the above-mentioned range, it is easy to apply to a resistance film type touch panel in which high transmittance and conductivity are ensured.

The conductive pattern 120 may be directly attached to the surface of the substrate 110, but it may be bonded to the functional group exposed by the surface treatment of the substrate 110, or may be attached via another intermediate layer such as an adhesive layer or a linker have.

Hereinafter, other embodiments of the present invention in which more various conductive patterns are implemented will be described.

4 is a plan view of a conductive film according to another embodiment of the present invention. Referring to FIG. 4, the conductive film according to the present embodiment is different from the embodiment of FIG. 2 in that the conductive patterns 120a, 120b, 120c, and 120d form a island pattern. The periphery of the first regions 121a, 121b, 121c, and 121d is surrounded by the first regions 121a, 121b, 121c, and 121d, The second regions 122a, 122b, 122c, and 122d having a smaller density are disposed. The island patterns may be insulated from each other, but they may be electrically connected to each other through a contact (not shown) or a connection wiring.

5 is a plan view of a conductive film according to another embodiment of the present invention. Referring to FIG. 5, the conductive film includes a plurality of first conductive patterns 220 and a plurality of second conductive patterns 320. The plurality of first conductive patterns 220 and the plurality of second conductive patterns 320 all include the conductors described above. Each of the first conductive patterns 220 includes a connection pattern 222 connecting the plurality of island pattern units 221 and adjacent island pattern units 221 to form a stripe pattern extending in the first direction Y as a whole And they are arranged repeatedly in the second direction X. The plurality of second conductive patterns 320 are formed in island patterns arranged between the island pattern portions 221 of the first conductive patterns 220. The island patterns of the first conductive patterns 220 and the island patterns of the second conductive patterns 320 have a matrix arrangement of staggered arrangement. The separated second conductive patterns 320 may be electrically connected in a second direction X perpendicular to the first direction Y through a contact or a connection wiring (not shown).

The first conductive pattern 220 and the second conductive pattern 320 are formed of a first region having a relatively large conductor density at the center portion and a second region having a relatively small conductor density at a peripheral portion of the first region . In some other embodiments, the connection pattern of the first conductive pattern may consist of only the first region, or may be a third region having a higher conductivity than the first region.

The conductive film according to the embodiments of the present invention described above functions as a transparent conductive film, and thus has a wide application range.

For example, the conductive film according to the embodiment of FIGS. 1 and 2 is applicable to a resistive touch panel. For example, two conductive films having a sprite pattern are arranged so that the conductive patterns cross each other in the direction in which the sprite patterns cross each other, and a large number of piezoelectric elements are interposed therebetween. can do.

Such a touch panel can improve the transparency and the conductivity at the same time, as described above.

In addition, the conductive film according to the embodiment of Fig. 5 can be applied to an electrostatic touch panel. Even in the case of such a touch panel, transparency and conductivity can be simultaneously improved.

Further, since the conductive film according to the embodiments of the present invention has both high transparency and high conductivity, it can be used as a pixel electrode or a common electrode of a liquid crystal display device, an organic EL display device, or the like. It is also applicable as a transparent electrode of a solar cell. It goes without saying that the present invention is also applicable to various displays and lights that require other transparent conductive films.

Hereinafter, a method of manufacturing a conductive film according to embodiments of the present invention will be described. It is to be understood by those skilled in the art that the method of manufacturing a conductive film described below is merely illustrative and that a conductive film according to various embodiments of the present invention can be manufactured in a more various ways.

The mask pattern 400 includes a side wall 402 that is inclined downward toward the open portion 410). The width of the open portion 410 corresponds to the width of the conductive pattern to be formed.

Referring to FIG. 7, there is provided a composition comprising a conductor 125 having a predetermined aspect ratio on a substrate 110 on which a mask pattern 400 is formed. Some of the conductors 125 included in the composition are disposed on the surface of the substrate 110 exposed through the open portion 410 while the other portion is disposed on the top surface 404 of the mask pattern 400, And is disposed on the side wall 402 of the mask pattern 400. Some conductors 125 are disposed on the surface of the substrate 110 at one end and the sidewalls 402 of the mask pattern 400 at the other end.

The conductor 125 is uniformly disposed at the central portion of the open portion 410 without any limitation in the arrangement of the conductor 125. The peripheral portion of the open portion 410, The mask pattern 400 may not be disposed entirely on the surface of the substrate 110 due to the influence of the side wall 402 of the mask pattern 400 and may extend between the substrate 110 and the side wall 402 of the mask pattern 400, As shown in Fig.

Next, the conductor 125 disposed on the substrate 110 is fixed on the substrate 110. Methods of securing the conductor 125 on the substrate 110 can include, for example, drying the composition. At the same time or separately, the conductor 125 may be fixed to the surface of the substrate 110 by applying light energy such as thermal energy or ultraviolet rays to the composition. Alternatively, the composition may be dried and then provided with an adhesive thereon to secure the conductor 125 on the substrate 110. The surface of the substrate 110 may be physically or chemically treated with a compound such as acid, plasma, ultrasonic waves, or the like before the composition is provided, or the linker may be interposed between the surface of the substrate 110 and the conductor 125, It is also possible to fix the fixing member. Other various methods of fixing the conductor 125 to the surface of the substrate 110 may also be applied.

Then, the mask pattern 400 is removed. When the mask pattern 400 is made of a photoresist pattern, it can be removed by ashing or stripper. When the mask pattern 400 is a hard mask, the mask pattern 400 can be removed using a dry or wet etching process.

The conductors 125 that were disposed on the surface 404 of the mask pattern 400 upon removal of the mask pattern 400 are removed together. At this time, the conductors 125, which were floated on the side wall 402 of the mask pattern 400, are also removed. The conductor 125 whose one end is disposed on the sidewall 402 of the mask pattern 400 and the other end is disposed on the surface of the substrate 110 may be removed or remained with the removal of the mask pattern 400 .

As a result, only the conductor 125 in the open portion 410 remains on the substrate 110 to form a conductive pattern. However, since the region adjacent to the side wall 402 of the mask pattern 400 is partially removed together with the removal of the mask pattern 400 as described above, only the conductor 125 having a smaller density than the center portion remains. 2, the remaining conductive pattern 120 is disposed in the peripheral region of the first region 121 and the first region 121 at the central portion, and is electrically connected to the conductive region 125, The second region 122 having a low transmittance and a low density.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, You will understand. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive.
