In particular, the liquid crystal display is improved with the image accuracy, and the conventional liquid crystal display is not The small bubbles and strain on the transparent conductive crucible which do not pose a problem constitute a cause of image defects, and it is required to further prevent generation of small bubbles and strain of the transparent conductive film. The present invention is directed to the above. The problem is to provide a method for producing a transparent conductive film, which can suppress the unevenness caused by the indentation, and can prevent the display port from being lowered without causing defects or strain of the image. !^ The method for producing a transparent conductive film of the invention is a method in which the first film (having a hard coat layer and/or an anti-glare layer on the first surface of the material 2) and the second base are A transparent conductive film flute layer is formed, and a film is passed through the adhesive layer to accumulate a transparent conductive film. The film is formed by the following steps: a coating layer is formed, and the first film is formed first. a roll of the first film of the appendage layer; and a step of laminating, the first film and the second layer of the transparent conductive film are formed by adhering the adhesive layer, and the adhesive layer is deposited 1 film manufacturing step is provided in the step of forming an adhesive sheet, and an adhesive layer is formed on the surface of the film layer 1 of the adhesive layer; the layer is supplied with the first film and drilled with an opening/v. The agent film is formed by the agent film (4)H and 1292114, and the two sides between the second surface and the first film of the separator of the first film with the adhesive layer are formed. The end portion is supplied with the spacer, and is wound around the wrinkle to form a roll body with the first layer of the adhesive layer; and 'the first part is supplied with a spacer at both ends and then wound around the core. 2 film roll body; the step of laminating is provided with a coating layer 彳 w w w w w w w w w w w w w w w w w w w w w w w w w w w w w w w w w w w w w w w w w w w w w w w w w w w w w w w w w w And the separator 2; the membrane 2 is supplied to the step partition; and the membrane 2 is rolled out from the roll body and the interlayer layer is removed = the secret layer is coated with the second layer of the film (4) The second two::: the manufacturing method of the film, the film (the second surface of the material is 1 more ancient coating and / or anti-glare layer) and in the second base layer, and manufactured: 1 conductive The second film of the enamel is spread through the layer of the agent to form a transparent guide of thunderamide. ^ Attached to the agent #The second film system, the temple sign has the following steps: Ling second film manufacturing step, for the flute The roll of the second film of the (four) agent layer is laminated on the = (four) to (four) agent, and the second film and the first film are dried, and the wind is obscured by the F-winding; The coating layer second film manufacturing step includes: forming a layer of the first surface of the film of the agent-attached agent layer 2 with a layer of the agent layer; forming a second layer of the film and performing the drying and the stepping In the winding step, the spacer layer 1292114 is supplied with a spacer, and the spacer is supplied to the both ends of the second film and the second film of the separator of the second film. The core forms a roll of the second film with the adhesive layer The first film is a first film roll that is wound around the core after the spacers are supplied to the both ends, and the second layer is supplied with the second film supply step. The second film with the adhesive layer is taken up from the roll body, and the spacer and the separator are removed. The first film supply step is performed by taking the first film from the roll body and removing the step of drying. The second film and the i-th film with the binder layer are laminated through the layer of the agent. In the above-mentioned invention, the first film, the second film, and the first film, the film, and the film, which are to be laminated, are wound into a roll body through a spacer and then subjected to a lamination step. The function of the substance is to prevent the film after winding from adhering to each other, and to use the spacer 'when it is wound into a (four) body for storage (4), since the pressure of the film can be reduced, even if the foreign matter adheres, the waist When the outer surface is attached to the hard coat layer, the anti-glare layer or the transparent conductive layer, the unevenness caused by the indentation is not easily generated. In particular, the first layer of the coating layer or the second layer of the coating layer is attached. Compared with the film of the adhesive layer, when the foreign matter adheres or is mixed, the pressure is generated by the film: The adhesive layer is plastically deformed and cannot be recovered. Although the ruthenium is likely to be indented, the winding is performed by the spacer, so that the pressure applied to the adhesive layer by the yoke is small and the indentation is less likely to occur. 1292114 Further, the "anti-glare layer" is formed by, for example, mixing transparent particles to form irregularities on the surface, and when the first film of the antiglare layer having such a structure or the first film of the adhesive layer is wound and placed, In the case where the foreign matter is mixed, the indentation is likely to occur in the same manner. However, since the winding is performed by the spacer, the generation of the indentation can be effectively suppressed. When the product produced by the laminating step, that is, the transparent conductive film is wound around the core to form a roll, it is still preferable to carry out the winding through the spacer. Further, the first film of the first invention and the second film of the second invention are both formed into a roll body and then supplied to the film preparation film 1 or the (4) agent layer second film production step 'and the roll body is compared Good is made by winding the spacers. Preferably, in the method for producing a conductive film, the spacer is a single layer, and in the winding step, the spacer layer forming surface of the spacer is brought into contact with the separator. supply. By using the gas having the adhesive 厣p between the layers, the film is wound around the core while the spacer is provided at both ends thereof.

Further, when the roll body is wound like a Fa1R ρ^, the problem of vapor displacement or falling off which is easily generated when moving can be avoided. It is preferable that the transparent conductive film of m is obtained by (4) laminating the layer of the first «drying agent layer, and the surface of the second substrate U2 is made transparent, whereby transparent conductivity excellent in optical characteristics can be obtained. membrane. 1292114 In this case, the first surface of the first substrate constituting the first film and the second surface of the second substrate constituting the second film may be treated without a treatment layer, but it is preferable that at least one of them has a polymer. Prevent layers. The action of the oligomer preventing layer prevents the oligomer contained in the first substrate or the second substrate from being transferred to the pressure-sensitive adhesive layer, resulting in poor appearance of the transparent conductive film. More preferably, the polymer layer is formed on the second surface of the first substrate and the second substrate. In the present invention, the spacer is preferably composed of a thermoplastic resin film because of its low cost. In the present invention, the width of the spacer is preferably 5 to 1 〇 〇 mm. When the width of the spacer is less than 5 mm, the pressure applied to each film in the first film or the second film roll cannot be sufficiently reduced, and the indentation is likely to occur. When the width of the spacer is larger than l〇〇mm, when the film is taken up from the roll body and stretched, the film area which is poor in appearance due to the occurrence of the trace of the spacer increases, and the effective product area becomes smaller. Not good. According to the method for producing a transparent conductive film of the present invention, a good transparent conductive film can be produced, and the number of indentations is reduced as compared with the prior art, and image defects and strains are not generated when the display is formed, and deterioration in display quality can be prevented. [Embodiment] The material of the spacer used in the present invention is not particularly limited. However, when the roll body is placed, it is necessary to prevent the transparent conductive film or the anti-glare film of the film from being dried or adhered. Specifically, a polyester such as polyethylene terephthalate, a polyurethane, a hard thermoplastic resin such as #vinyl chloride, polystyrene, polyethylene, or polypropylene, a fine Japanese paper, a non-woven fabric, or the like may be used. A material excellent in cushioning properties such as a foamed polyurethane sheet or a beaded polyethylene sheet. Use spacer 10 1292114 to make spacers
