2186-9603-PF 17 200907755 : Fixed side mounting part and moving side mounting part. The chamber surface of the fixed side mold (1): the layer (3), the film 131 is placed in the edge layer of the central layer, and the interlayer mold is used to remove the layer using the diaphragm moving device 103, and the clip is made. The 桓 film moving device 103 starts to operate. Here, the device 103 is a sandwich between the fixed side mold 111 and the moving side mold which is located at the door of the ln9 沾π 杈 杈 4 The mold film (3) is moved only by a predetermined long sound. Next, the injection molding machine 104 is started to operate. At this time, the injection mechanism of the machine 1〇4 moves the moving side mounting portion to the fixed side mounting portion, such as As shown in Fig. 7, the main body portion 113 of the fixed side mold (1) and the main body portion 123 of the movable side mold are joined to each other with the interlayer mold film ΐ3 therebetween. Next, the injection mechanism of the injection molding machine 1〇4 pushes the resin in a flowing state under pressure. At this time, as shown in Fig. 7, the resin pushed by the pressure from the injection molding machine 1〇4 passes through the main wash channel 1Q2b, and is emitted from the wash port (10)c into the cavity t102a. In this case, in this mold 1 2 as shown in the drawing, the gate l 2 c is the side of the chamber surface i 〇 2 e disposed in the chamber surface 1 〇 2 d ' and located along the chamber The position of the position in the X-degree range of the interlayer mold film 131 in the longitudinal direction is not the position of the position where the interlayer weight film 131 is provided in the chamber surface 1 〇μ. Therefore, the resin injected into the chamber 102a from the washing port 1 〇 2 c is filled in the chamber 1 〇 2a while pressing the interlayer mold film 131 to the side of the chamber surface 102f. Further, the adhesive layer 134' of the interlayer mold film in between the tree and the cavity to the surface 102f is adhered to the resin filled in the chamber i2a by the pressure of the resin. In this case, in this mold 102, as shown in Fig. 8, since the uneven portion 141 is formed on the chamber surface 1〇2f, the shape (concave-convex shape) of the uneven portion 141 is transferred. As a result of the film ι3 of the interlayer mold which is interposed by the chamber surface 102f, the uneven portion 21 having the concave portion 22 and the convex portion 23 having the fine strip shape is formed in the transparent conductive film 12 of the interlayer mold film 131. Here, since the base film 132 of the interlayer mold film 131 is formed of a resin having moderate flexibility and elasticity as described above. Therefore, as shown in the nth figure, in the conventional mold 302, the cavity surface 3〇2f is formed with a concave-convex portion 341 having no flat shape and a triangular cross-sectional shape, and the base film is formed by the elasticity of the base film 132. The 132 does not completely adhere to the entire surfaces of the concave portion 342 and the convex portion 343 which constitute the uneven portion 341, and a gap is formed between the bottom 3 film (3). That is, the base film 132 serves as a buffer for accurately transferring the shape of the uneven portion 341 to the transparent conductive film 12, and the height of the uneven portion 21 formed on the transparent conductive film 12 from the bottom portion 22a to the top portion 23 & The depth L12 is lower than the height (depth) L11 of the mold 302 from the bottom 342a to the top, and the difference between the two is the gap between the bottom 342a and the base film 132. As a result, although a fine interference fringe for avoiding generation of an interference fringe which affects the image recognition is formed, it is difficult to secure the height from the bottom portion to the top portion 23a (the above-described height L11). On the other hand, in the mold 1 2 of the present invention, the uneven portion 141 has a configuration in which the bottom portion 142a is formed as a plane parallel or substantially flat with respect to the reference surface 144, and the convex portion 143 whose top portion 143a is formed to be A plane parallel or substantially parallel to the reference plane 144; and a ramp 145 joining the bottom 142 & and the top 143a. Therefore, even the elastic base film 132 is not

2186-9603-PF 19 200907755 is completely adhered to the entire surface of the uneven portion 141, and as shown in Fig. 1A, the base film 132 can be surely adhered to the bottom portion 142a of the concave portion 142 and the top portion 143a of the convex portion 143. As a result, the height L11 of the uneven portion 141 in the mold 1 2 from the bottom portion 142a to the top portion 143a can be the same as the height L1 of the uneven portion 21 in the transparent conductive film 12 from the bottom portion 22a to the top portion 23a. That is, the height L1 from the bottom portion 22a to the top portion 23a of the uneven portion 21 formed by the use of a mold 102 is larger than the south degree L12 from the bottom portion 22a to the top portion 23a using the conventional mold 302. . Therefore, the case of the present invention is to generate fine interference fringes for avoiding generation of interference fringes which affect the recognition of an image, and it is possible to surely ensure the height from the bottom portion 22a to the top portion 23a to a necessary height (height L1.1). . Then, after a predetermined cooling time, the mold clamping mechanism of the injection molding machine 1〇4 moves the moving side mounting portion in a direction away from the fixed side mounting portion, thereby releasing the fixed side mold ln and the moving side mold 121. The joining between the movable side molds 121 is detached from the fixed side molds lu. At this time, the molded article (i.e., the substrate 11) molded by the curing of the resin is separated from the movable side die 121 from the fixed side die 1U. Next, the ejector mechanism for injecting the forming machine 1 to 4 moves the top plate 125 of the moving side mold 121 to the side of the second portion 123, whereby the ejector pin other than the figure protrudes from the month j of the body portion and is formed. The substrate 1 1 is taken out from the moving side mold 丨 2 。. In this case, since the adhesive layer 134 is adhered (attached) to the substrate u, the interlayer film 131 is also brought out from the moving side mold together with the substrate u. Next, the base m 132 of the interlayer mold film 131 is removed from the substrate (four)

2186-9603-PF 20 200907755 away. In this case, because the transparent guide is to persuade m to be refined by the adhesive layer 134 from the transparent guide: cavity? In the state of the inner surface η3, the base film 132 is easily permeable to: the transparent conductive material is bonded to the inner surface, and the system is formed into a transparent surface of the substrate U and the inner surface & The manufacture of the lower electrode 2a composed of the conductive film 12. Next, the upper electrode 2b is fabricated. In the first game I light, indium oxide f indium (ίτ〇) which is implanted as tin as a raw material for forming a transparent conductive film is applied to one side of a transparent sheet 31 formed of, for example, PET, and 藓 沭 / 沭 bb w w ^ q9 pull A thereby forming the transparent conductive film 32 on one side of the transparent sheet. Next, the hard coating film and the anti-reflection processing are applied to the other side (touch surface) of the moon sheet 31. Then, the transparent and transparent film 2 which has completed the formation of the transparent conductive film 2 and the above-described processing are cut into a predetermined size (about the same size). Thereby, the manufacturing of the upper electrode 2b is completed, and the transparent conductive film 12 of the lower electrode 2a and the film 32 of the upper electrode are opposed to each other, and the dot spacer 3 is sandwiched between the lower electrode a and the upper electrode. Between the crucibles, the electrode 仏 and the outer edge portion of the electrode 2b are adhered in this state by using an adhesive or the like. Next, the connecting end is attached to the outer edge portion of the lower electrode 2a, the φ...electrode 2b, and the transparent conductive film 12 and the upper electrode 2b of the lower electrode are bonded to the inner surface 11a of the base 11 liArinT· at the same time. The transparent conductive film m is connected to the connection terminal 4. Thereby, the touch panel 1 is completed. In this case, the mold 1G2 towel, as described above, is formed by the mold 102, and the lower Leiqi 9 is formed by the sandwich mold of the + a spent electrode 2a, and the transparent guide 12 is formed with the 'concave portion 21, poor &quot A produces A, "the height of the bottom 22a to the top 23a of the crucible is the height necessary to generate fine interference fringes. Therefore, it can be surely avoided

2186-9603-PF 21 200907755 Free of interference patterns that affect the recognition of images. Therefore, in the touch panel 1, the image or the like displayed on the inner side of the touch panel 1 that has been mounted on the object to be mounted can be clearly recognized. As described above, in the method for manufacturing the interlayer mold 102 and the touch panel, the lower electrode is manufactured by ejecting the resin to the chamber 102a' formed by the chamber surface 102f in which the uneven portion 141 is formed. 2a. The uneven portion 141 has a configuration in which a plurality of strip-shaped recesses 142 and a convex portion f 143' have a bottom portion 142a and a top portion 14a formed in a plane parallel to the reference plane 144, and are parallel (or substantially parallel); the concave portion 142 and the convex portion The portions 143 are alternately arranged side by side; and the joint faces of the bottom portion 142a and the top portion 143a are respectively inclined faces 145. Therefore, the sandwich molding die 1 2 and the touch panel manufacturing method are different from the conventional mold 3 in which the uneven portion having no flat surface and a triangular cross section is formed on the chamber surface 302f. 2. Even if the base film 132 of the elastic interlayer film 131 is not completely adhered to the entire surface of the uneven portion 141, at least the base film 132 can be surely adhered to the top of the bottom portion 142a and the convex portion M3 of the concave portion 142. 143a. Therefore, the height from the bottom portion 142a to the top portion 143a of the uneven portion 141 in the mold 1 2 can be the same as the height from the bottom portion 22a to the top portion 23a of the uneven portion 21 in the transparent conductive film 12. As a result, the mold 1〇2 and the intermediate manufacturing method for the touch panel generate a fine interference pattern for avoiding the interference pattern which affects the recognition of the image, and as a result, the bottom portion 22a can be surely ensured. The height to the top portion 23a is a necessary height li, and the lower electrode 2a which can clearly recognize an image or the like can be manufactured. In addition, by means of the sandwich mold 1 〇 2 and the middle of the touch panel

2186-9603-PF 22 200907755 The body manufacturing method is such that the concave-convex portion 141 has a configuration in which the concave portions 142 have equal pitches and the convex portions 143 have equal pitches between the convex portions 143, and the mold 102 is used. The electrode 2a is formed, whereby the uneven portion 21 having the same pitch between the concave portions 22 and having the equal pitch between the convex portions 23 & can be formed on the lower electrode 2a. Therefore, it is possible to surely avoid the case where the concave portion 22 and the convex portion 23 appear to be, for example, irregular patterns due to different pitches, causing a user to have a strange feeling.

In addition, the interlayer mold dies 2 and the touch panel intermediate manufacturing method have the bottom portion 142a, the top portion U3a, and the slope 145 along the widths WU and W12 of the reference surface 144, respectively. W13 is equal to each other, and the lower electrode 2a is formed by using the spoke_@θθ, and the width of the bottom portion 22a, the top portion 23a, and the slope portion 25 can be made to each other. Equal concave and convex portions 21 are formed on the transparent conductive film 12. Therefore, it is possible to surely prevent the skew of the image f __ phantom image (displayed content) displayed on the inner side from being changed due to the position of each of the different widths W11, W12, W13, and the image recognition occurs. The problem of obstacles. In addition to the W1n force, the respective widths wil, W12, and W13 described above are equal to each other and are concave. The respective pitches of the ridges 142 and the convex portions 143 are reduced, so that the uneven portions 21 of the transparent conductive film 12 formed on the lower electrodes 2a are less noticeable. Further, by making the respective widths W11, W12, and W13 equal to each other and narrowing the respective pitches of the concave portions 142 such as the shirts 143, the touch panel 1 performs the touch-flip operation. The narrow path of the interval between the fine dry, the horn, and the interference pattern (shading) caused by the ridges 21 of the transparent conductive film 12 is caused to be generated by the touch operation. Among the contours of the recess of the control panel 1 (limited to the contour 琛). Therefore, the above can be made

2186-9603-PF 23 200907755 The fine interference pattern is hidden to a degree that is almost indistinguishable under the naked eye. In addition, the concave and convex ridges 21 have a plurality of strip-shaped recesses 22 and convex portions 23 by forming the uneven portion 21 on the transparent conductive film 12 by the touch panel 丨 and the lower electrode 2a for the touch panel. The bottom portion 22a and the top portion 23a are respectively formed as planes parallel or substantially parallel to the reference surface 24, and the joint surfaces of the bottom portion 22a and the top portion 23a are respectively formed by the inclined surface 25, which generates interference for avoiding influence on image recognition. The fine interference fringes of the grain can surely ensure that the height of the bottom portion 22a to the top 23& is the necessary twist L1. Therefore, in the state in which the touch panel i and the touch panel 1 are mounted on the object to be mounted by the second "2a", the image or the like displayed on the inner side of the touch panel can be clearly recognized. However, the present invention is not limited by the above constitution. For example, the above description is made by taking a rectangular plate-shaped substrate Π as an example. However, the plate-shaped substrate u may be formed without being limited thereto. Further, the lengths of the bottom portion 22a, the top portion 23a and the bevel support widths M to w3 of the transparent conductive film 12, and the widths 11 W13 & lengths of the bottom portion 142a of the mold 102, the top portion U3a, and the inclined surface 145 can be arbitrarily set. Further, the bottom portion 22a to the top surface of the uneven portion 21 of the transparent conductive film 12 and the bottom portion 142 of the concave and convex portion 141 formed on the chamber surface 10 of the mold 102 are at the top. In the above description, the range of the configuration of L11 is 0.5" or more, and 3 (four) or less, but the height can be arbitrarily set. Further, the bottom portion 22a, the top portion 23a, and the slope portion 25 are respectively along The width of the reference surface 24 ^^ and the bottom (4)

2186-9603-PF 24 200907755 and the configuration of the slopes 145 along the widths W11, W12, and Π3 of the reference plane H4, respectively, in the above description, the range is 〇. 〇5mm (inclusive) or more, 〇.4πιπ] (inclusive) or less, but the above width values can also be arbitrarily formulated. In the above description, the example of the configuration of the uneven portion 21 is such that the width Π, W2, and W3 are equal to each other, and the configuration of the uneven portion 141 is such that the widths W11, W12, and Π3 are equal to each other. It is also possible to adopt a configuration in which the widths η ” are mutually different and the widths wu, W12 and W13 are different from each other.
