[Prior Art] A film for an intermediate body for a touch panel can be produced by in-mold molding. The in-mold mold core disclosed in Japanese Laid-Open Patent Publication No. Hei. The structure of the in-mold mold has a movable mold core and a fixed mold, and the touch panel substrate can be manufactured by in-mold molding. In the in-film coix seed, the transfer film (the film for film use) is joined to the two mold cores while the transfer film is inserted into the pores, and the resin material is ejected from the channels to the pores in this state. Thereby, the touch panel substrate is molded and the transparent electrode film (transparent conductive film) of the film is transferred (bonded) to the touch panel substrate. In this case, the touch panel substrate manufactured by the above-mentioned film inner mold can be used, for example, for a resistive film type touch panel. Specifically, the resistive film is formed by juxtaposing the touch panel substrate in a state in which the dot spacers are sandwiched and opposed to the transparent conductive film, and bonding the edge portions of the two touch panel substrates in the state. Touch panel. In the resistive film type: touch panel, when a touch stylus or the like touches one of the surfaces of the two touch panel soil plates, the contact operation portion 2186~96〇4- Pp 5 200849285 is in contact with another touch panel substrate, and the resistance 値 changes. As a result, the touch panel is detected as a (four) portion by detecting the change in the resistance 并 and positioning. 。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。 That is to say, in the above-mentioned resistive film type touch panel using the touch panel substrate formed by the above-mentioned in-mold mold, a Newton ring is generated in this portion because the operated portion is slightly recessed. = TM), and the visibility of the image displayed on the deep side is reduced. y technology to solve the problem, for example, as in (4) 2GG5_18 (10) U newspaper revealed that the transparent composite material - like the identification of the generation of the shadow of the gentleman to receive the Gan-丄 ^ m ^ ~ K structure, the difference is the triangle The fine part (the rib-like uneven portion) having a height of about two V°'m is formed on the film and generates fine interference fringes (Newton's rings). In this case, when the above-mentioned transparent composite material is produced by the in-mold mold core, generally, two: a fine rib-like shape is formed by the molding surface (pore surface) of the mold core in the film: : Shape: To a transparent conductive film (type), and to form a technique for the correct mold unevenness on the molding surface of the mold core in the film, a technique of extremely high height is required, and thus the inside of the film is used. 1 is a cost increase, and there is a problem that the manufacturing cost is difficult to reduce. [Invention] 2186-96〇4, Pf 200849285 By the above problems, the main object of the present invention is to provide a film: and a touch panel. The intermediate manufacturing method is used in order to reduce the manufacturing cost of the intermediate body for the touch panel. In order to achieve the above object, the film for film use of the present invention comprises a base film made of a resin and a transparent conductive film formed on one side of the base film; and the substrate of the transparent conductive film and the intermediate body for a touch panel One of the substrates for the touch panel is formed by sandwiching the substrate in the mold for molding in the film, and is formed by injecting the resin into the pores for molding the film; In the other surface of the base film and at least one of the dielectric films, a concave portion in which a rib-shaped concave portion and a rib-shaped convex portion are alternately formed is formed. In this case, the pitch at which the concave portions are adjacent to each other and the adjacent shape of the convex portions are defined as the same pitch. Further, the uneven portion is formed on the other surface of the 6-well base film. Further, in the method for producing an intermediate body for a touch panel of the present invention, a substrate for an intermediate body for a touch panel is formed by injecting a resin into a pore of a mold core in a film, and the transparent conductive film is bonded to one surface of the substrate to manufacture the touch. For the control panel, the film is used in the film, and the film is used to sandwich the film (4) film for forming the film. The film for film formation in the film is in the tree month. The transparent conductive film is formed on one surface of the base film made of tantalum, and the intermediate film for the touch panel is manufactured by sandwiching the film for film use in the mold for molding in the film. In the film for film use, the uneven portion formed by the rib-like concave portion and the rib-like convex portion are alternately formed on the other surface of the base film 2186-9604-PF 7 200849285 and at least one of the transparent conductive film . Further, in the method for producing an intermediate body for a touch panel according to the present invention, a substrate for an intermediate body for a touch panel is formed by exposing a resin to a pore of a mold core in a film, and the transparent conductive film is bonded to one surface of the substrate to manufacture the touch. In the intermediate body for the panel, in the film, the mold core is used for sandwiching the film, and the film for film use is used, and the film for film forming is used for the base film made of resin. A transparent conductive film is formed on the surface of the film, and the film for transferring the uneven shape is disposed in a state in which a film surface of the surface of the substrate which is formed in the pores is formed between the film and the film for film use. In the film for film forming, the film for the uneven shape transfer and the film for film use are used to produce the intermediate body for the touch panel, and the film T for the uneven shape transfer and the concave portion of the rib shape The concave and convex portions formed by the rib-like convex portions are alternately formed on at least one of the one side and the other side. The above and other objects, features, and advantages of the present invention will become more apparent from the aspects of the preferred embodiments of the invention. In the film for the film and the method for producing the intermediate layer for a touch panel, at least one of the other surface of the base film and the transparent conductive film is formed by the concave portion formed by the concave portion and the convex portion of the rib shape being alternately provided. The nucleus of the film type which is formed by the film and the pore surface of the film which is not formed into a fine portion is formed by the use of the film. Therefore, compared with the conventional manufacturing method using the mold core in the film having fine concavo-convex portions formed on the pore surface, and the intermediate body for the touch panel, it is possible to sufficiently reduce the surface of the touch panel. The manufacturing cost of the portion where the uneven portion is not necessary and the mold for molding in the film. Therefore, according to the method for manufacturing an intermediate body for a touch panel, the manufacturing cost of the mold for in-film molding can be reduced, and the manufacturing cost of the intermediate body for the touch panel and the touch surface can be sufficiently reduced. . Further, according to the film for film film of the present invention, the pitches of adjacent concave portions in the uneven portion and the pitch at which the adjacent convex portions are formed are respectively set to be the same pitch, and the pitches of the respective concave portions are equal to each other. Further, the uneven portions of the respective protrusions (4) may be formed on the transparent conductive film. As a result, it is possible to surely avoid the problem that the user sees that the concave portion and the convex portion exhibit an irregular pattern because the above-described formation pitches are different. Further, according to the film for film in the film of the present invention, since the uneven portion is formed on the other surface of the base film, one surface of the base film can be formed into a flat state, so that the material for the transparent electrode can be applied to the base film. On one side, a transparent conductive film having a uniform thickness is efficiently formed. As a result, an intermediate for a touch panel in which the thickness of the transparent conductive film is uniform can be produced. In addition, according to the method for producing a touch panel for a touch panel of the present invention, an intermediate body for a touch panel is manufactured by using a film for uneven shape transfer, so that an intermediate for a touch panel can be formed by in-mold molding. The transparent conductive film forms a concavo-convex portion. In the above-described in-flag molding, the film for uneven shape transfer which can be produced inexpensively, the film for film formation for film formation, and the film which does not form fine uneven portions on the pore surface of 2186-9604-PF 9 200849285 are used. In the film for forming a concave y-shaped turn, the concave-convex portion in which the concave portion of the rib shape and the convex portion of the rib shape are alternately formed is formed on at least one of the one surface and the other surface. In the conventional manufacturing method for producing an intermediate body for a touch panel by forming a fine indentation on the pore surface, it is possible to sufficiently reduce a portion where the uneven portion is not formed, and an in-mold molding mold. Ren's production costs. Therefore, according to the intermediate body manufacturing method for the touch panel, the manufacturing cost of the mold for molding in the film can be reduced, and the manufacturing cost of the intermediate body for the touch panel and the touch panel can be reduced by the squeezing blade.

Specifically, the uneven portion 141 is configured to have a height (depth) L11 from the bottom 142a of the concave portion 142 to the top portion U3a of the convex portion 143 within a range of 3 or less. Further, the 'concave portion 141 defines a pitch PH between the adjacent concave portions 142 and a pitch m between the adjacent convex portions 143 at the same pitch (for example, 〇.5 咖〇〇 4 4 or less) The spacing inside). In this case, as shown in Fig. 7, in the embodiment, the uneven portion 14 is formed by a roller having a crotch portion on the surface (...丨 2〇1 and a flat roller 2〇2) The base film 132 is interposed therebetween, and the shape of the roller 2 (the shape of the crotch portion is transferred to the surface 132a of the base film) is formed. The transparent conductive film is emulsified by, for example, oxidized steel such as tin-doped tin. Indium is formed so as to sandwich the peeling layer outside the drawing, and a film having a thickness of about 0.5 #m to 5 Am is formed on the back surface 132b of the base film!32 (one surface of the substrate of the present invention).

In the embodiment, the 'injection molding 胄m portion, the moving side arranging portion, the splicing mechanism, and the preparation port side are not shown in the figure), and the like. The steps of manufacturing the touch panel 1 using the manufacturing method for the intermediate body of the touch panel using the manufacturing device will be described with reference to the drawings. The electrode 2a is first shown in Fig. 3, outside the drawing of the injection molding machine m. The fixed side arrangement portion and the moving side arrangement portion are respectively disposed with the fixed side 111 and the movable side mold m of the mold core 1〇2. Then, (4) the layer is opposite to the concave surface 102e of the fixed side weight (1), and the inside of the film is Membrane ΐ3ι is placed in the membrane for moving the membrane 1〇3, and the membrane is moved by the membrane At this time, the film moving device 103 for film is moved between the fixed side mold core lu and the moving side mold core 121 of the mold core 1〇2, and the film for film use 131 is moved only by a predetermined length. Then, the injection molding machine 104 is actuated. At this time, by the injection molding machine, the t-shaped mechanism moves the moving-side arrangement portion to the fixed-side arrangement portion as shown in Fig. 5, and the main body portion (1) and the movement of the fixed-side mold jjj are moved. The main body portion 123 of the side scorpion 121 is joined while sandwiching the film I" in the film.

As a result, the resin which is ejected from the shutter 102c to the inside of the opening 102a presses the film 1i in the film to the side of the hole surface 102f and fills the hole 1〇2a. Further, as the resin is filled, the adhesive layer 134 of the film 1 31 for film use is adhered to the resin. On the other hand, as shown in Fig. 8, in the film for film film 131 which is pressed to the side of the pore surface 102f by the resin, the film 131 is formed on the convex portion 143 of the uneven portion 141 formed on the surface 132a of the base film 132. The top portion 143a is initially joined to the aperture face 1 0 2 f. Then, as the pressure of the resin opposed to the film 丨3丨 in the film increases, as shown in Fig. 9, the convex portions 143 which are connected to the gap faces 1〇2f are deformed. In this case, the portion opposed to the convex portion 143 of the transparent conductive film 12 passes through the convex portion 143 and is opposed to the resin side (the surface of the pore surface 1〇2e) applied by the aperture surface 102f. On the other hand, it is pressed against the resin side, and ISU 突出 protrudes toward the resin side and is deformed. In contrast, since the portion opposed to the concave portion 142 of the transparent conductive film 12 is not subjected to the reaction force from the aperture surface 102f (or only the reaction force is not protruded to the resin side). I, and the inside of the film 臈13! : No, the concave portion 142 of the uneven portion 141 and the convex portion H3 are flush with each other, and the convex portion U3 is generated in a state of being connected to the concave surface. When the portion which is located at the convex portion of the transparent conductive film 12 is further pressed toward the resin side, the progress of the protrusion is increased toward the resin side. As a result, the shape of the image U ^ ° 卩 141 is transferred.

In this embodiment, the in-film film formed by using the film on the surface of the base film and the mold-in-mold in which the fine uneven portion is formed on the pore surface, and the manufacturing of the lower electrode 2a by in-film forming are manufactured. In the method, since a technique of extremely high height is required to form fine concavo-convex portions on the pore surface, the production cost of the in-mold mold core is rapidly increased. Therefore, it is difficult to reduce the manufacturing cost of the lower electrode 2a and the touch panel 1. In contrast, in the method for producing an in-film for a touch panel of the present invention (the method for producing an intermediate body for a touch panel of 131), since it is not necessary to form a fine uneven portion facing the pore surface 102f, the mold core 1 2 can be produced inexpensively. In addition, as described above, the film for film use 131 can be produced at a low cost. In the film forming method for the film 131 and the intermediate body for a touch panel of the present invention, the lower electrode 2a and the touch panel can be sufficiently reduced. After the predetermined cooling time has elapsed, the movement mechanism is moved from the fixed side arrangement portion to the direction away from the fixed side arrangement portion by the molding mechanism of the injection molding machine 104, and the fixed side mold ln and the movement are moved. The joining of the side mold core 121 is released, and the moving side mold core 2 is removed from the fixed side mold core 1 1 1. At this time, the molded product (that is, the substrate u) and the moving side are formed by curing the resin. 121 - peeling off from the fixed side mold ln. Then, the eject plate 125 of the moving side mold i2i is moved toward the body portion 123 side by the eject mechanism of the injection molding machine 1〇4, outside the drawing The thimble (4)...pin) is before the body portion 123 Projection 'is taken out of the substrate molded from the mobile u-side mold core 121. In this case, since the (four) layer 134 is adhered (attached) to the substrate π, the film inner film 131 and the substrate 11 are taken from the moving side mold core 121 together with 218 6 to 9604-PF 18 200849285. Next, the base film 132 of the film 131 for film is peeled off from the substrate π. In this case, since the transparent conductive film 12 is attached to the inner surface i ia of the substrate 11 by the adhesive layer 134, the base film i 32 is easily peeled off from the transparent conductive film 12, and the transparent conductive film 12 fits the inner surface n. Thereby, the lower electrode 2a composed of the substrate n and the transparent conductive film 12 bonded to the inner surface 11a of the substrate u is completed. Next, the upper electrode 2b is fabricated. In this case, first, a tin-doped oxidized steel of a conductive material is coated on a surface of a transparent thin film 31 made of, for example, PET, and a transparent conductive film 32 is formed on the transparent thin plate. Next, on the other surface of the transparent thin plate 31 (electrical V:::/layer processing and reflection preventing processing. Next, the formation of the transparent guide and the above-mentioned processed transparent thin plate 31 are cut into predetermined ones, and the lower electrode 2a is approximately The same size) 2b is finished. On the other hand, the upper electrode is opposed to the transparent conductive film 32 of the transparent conductive film 12 of the lower electrode 2a, and the second layer is used, and the second gap between the two electrodes is used to sandwich the point gap stone. Electrodes 2a, 2h. Technically, the terminal 4 for connection is disposed in the peripheral portion of the two electrodes 2a and 2b, and the inner portion 4 of the substrate u of the lower electrode 2a is connected to the touch panel: the conductive core 2 is connected. Therefore, in this case, the uneven portion 21 composed of micro is formed on the touch panel as described in the thin concave portion 22 and the convex portion σ σ

As a result, when the touch panel 1 is touch-operated, the presence of the uneven portion 21 causes fine interference fringes to the extent that the human eye cannot recognize the touch-operated portion, thereby avoiding obstacles to recognition. Large interference fringes. So in the touch panel! In the state of being mounted on the configuration target body, it becomes possible to be in the touch panel! The depth of the display makes the displayed image very distinctive. In the case of the in-mold film 131 and the method for manufacturing the intermediate body for a touch panel, the uneven portion 141 formed by alternately arranging the ribs (four) 142 and the rib-like convex portions is formed on the base film 132. The lower electrode 2a is produced by using the film inner film i3i including the base film 132 on the surface 132a', and the uneven portion 2 can be formed by the in-film molding using the film core 1 2; the transparent conductive film 12 of the partial electrode 2a. In the film core 102, fine concavo-convex portions are not formed in the film which can be inexpensively produced, and the film surface 10b and the pore surface l〇2f. As a result, compared with the conventional manufacturing method in which the lower electrode 2a is produced by using the mold core in the film in which the fine uneven portion is formed on the pore surface, the uneven portion opposite to the pore surface 1〇2f can be sufficiently reduced. Part, the manufacturing cost of the mold core 102. Therefore, the manufacturing cost of the mold core 102 can be reduced by the film 1 31 in the film and the two tongues of the intermediate method for manufacturing the touch panel, and the manufacturing cost of the lower electrode 2a and the touch panel 1 can be sufficiently reduced. In addition, according to the method for creating the film for inner film 31 and the intermediate method for the touch panel, the formation pitch of each concave portion 142 is equal and long, and the formation pitch of the 1 1 1 4 3 is equal to the base. The film 132 constitutes the concavo-convex portion 141, and the in-film electrode 131 including the base film 132 is used to form the lower electrode 2186-9604-PF 20 200849285 2a', and the concave portion 22 can be formed with a pitch shank or the like and each convex 23 can be formed. The uneven portion 21 having the same pitch is formed on the transparent conductive film 12. As a result, it is possible to surely avoid the problem that the user sees that the concave portion 22 and the convex portion 23 exhibit an irregular pattern due to the difference in the above-described formation pitch. Further, according to the film-forming film 131 and the method for producing an intermediate body for a touch panel, since the uneven portion u is formed on the surface u2a of the substrate m 132 and the lower electrode ^ is formed using the film for film use 131, Since the back surface 132b of the base film 132 is formed in a flat state, the transparent conductive film 12 having a uniform thickness can be efficiently formed by applying the material for the transparent electrode to the back surface 132b. As a result, the lower electrode 2a having a uniform thickness of the transparent conductive film 12 can be manufactured. Moreover, the present invention is not limited to the above configuration. For example, although the crucible 131 is formed by using the crucible 131 as the inside of the surface 132a of the base film 132 (the other surface of the base film of the present invention), the film 231' for the film as shown in FIG. In addition to forming the surface (10) flatly, it is also possible to form the uneven portion 141 on the transparent conductive film 12 including the dry layer 134 and the back surface 132b of the substrate 32 (corresponding to the other surface of the base film of the present invention). structure. Further, the film 331 for film in the film shown in Fig. 12 may be formed by forming a concave-convex portion 141 on the surface 132 a of the transparent guide wire and the surface 132 a of the base film 132. Further, although the rectangular plate-shaped substrate and the factory transparent conductive crucible 12 are described as an example, the present invention is not limited to this, and can be applied to a substrate having an arbitrary shape, as shown in FIGS. 13 and 1 d & π 4 does not use the film 431 for film and the film 531 for irregular shape transfer f f I 卩卩卩 electrode 2a (others of the present invention)
