Priority is claimed on Japanese Patent Application No. 2007-306418, the entire disclosure of which is incorporated herein by reference. [Prior Art] In recent years, the application of touch panels has become more and more widespread, and more and more touch panels have been installed on portable information devices. In a portable information device, such as a mobile phone, a small-sized game machine, and the like, it is naturally desirable to have a lightweight and thin profile device and a structure that can withstand a drop collision without failure. . Therefore, a conventional touch panel based on a thin film glass structure, a touch panel based on a plastic material such as FFP, FF, FP has become more widely used. In another aspect, a foldable type structure has been increasingly adopted in mobile phones or mini-game machines. Many conventional machines employing a folding type structure have two screens, one of which is used as a display screen and the other surface is used as an operation panel having a push button switch and a pointing device mounted thereon. When a touch panel is applied to such a device, the touch panel 'i', that is, the display screen, is provided only on one of the two surfaces. However, the function of having a display screen on the surface of a recent device 129956.doc 1375168 has appeared, and its demand is increasing. In such a device, an attempt has been made to apply the touch panel to the second display screen. In order to apply the touch panel to the device having two display screens, as shown in FIG. 14, two touch panels are required. 70, 80. Therefore, there is a problem that two sets of flexible circuit bodies 71 and 81 are required for the two touch panels, and the structures of the touch panels are inevitably complicated. Accordingly, the present invention has been investigating a single sheet type touch panel that can be folded into two and form a two-screen of the wheeling operation area. Although not directly related to the present invention, Japanese Patent Application Laid-Open No. 340151 discloses a foldable type a la carte terminal having a plurality of switch sheets. In this ordering terminal, an adhesive ring is fixed to a substrate, and a plurality of switch sheets are bonded in the form of a bonded type book. Each of the switch sheets is composed of five resin sheets attached together. The switch sheets have a circuit body in which switches are formed. In the conventional resistive film type touch panel, the ruthenium film is used as a conductive film. Since the ΙΤ0 film is hard and brittle, like a thin glass plate, there is a problem: when the sorghum film When bent - a small radius of curvature R, cracks and the conductive properties of the film are impaired. That is, there is a problem that the tantalum film is damaged due to stress applied to the curved portion of the tantalum film: 3⁄4 f columns such as 'confirmed' if the ΙΤ0 thin medium is folded with a corner half 裣 R 1.0, in a few Subsequent and dozens of repeated folding and opening causes a change in resistance (see Figure 9). SUMMARY OF THE INVENTION 129956.doc 1375168 layer, can effectively weaken the blue color of the conductive polymer material. In the touch panel described above, an external circuit configuration can be electrically connected to the fixed side conductive film and the operation side conductive film at a position via a predetermined line pattern. Since an external circuit configuration such as FpC is connected to the position, the structure of the touch panel can be simplified. The touch panel as described above can be applied to a folding type information device having two folded liquid crystal u areas so that the two input operation area is attached to the z ^ liquid crystal area. The touch panel can also be applied to an electronic paper that displays an image by applying a magnetic field or an electric field. Since the touch panel can be formed on the liquid crystal area of the folding type information device or on the electronic paper, the operability of the information input to the information device can be improved, and the application range of the touch panel can be expanded. The above and other objects, features and advantages of the present invention will become apparent from the <RTIgt; [Embodiment] Now, the present invention will be described in detail with reference to the drawings showing specific examples of the embodiments thereof. 1 is a view of a touch panel in accordance with an embodiment of the present invention. As shown in FIG. 1 , a resistive film type touch panel 1A of this embodiment includes: a fixed side substrate (film) 11 , the fixed side substrate is attached to a liquid crystal screen; and an operation side substrate The (film) 12 is a substrate which is pressed by a finger, a stroke or the like, disposed opposite the fixed side substrate U; and an FPC connector 13 electrically interconnects the two substrates to the main body of the device. The touch panel 10 is applied to one of two liquid crystal screen regions 129956.doc • 10· 1375168 On the opposite surfaces of the two substrates 11, 12, a conductive polymer is coated as the conductive films 20,21. The conductive polymer of this example is a polythiophene-based polymer and is very transparent (translucent). It is generally preferred that the transmittance of the touch panel is 80% or higher and for a film having a thickness of about 5 nanometers, the transmittance of the touch panel can be 90% or higher. Other polymers can be used as the conductive polymer as long as they are very transparent, for example, a polyacetylene-based polymer, a polypyro-based polymer, or a polyphenylene-based polymer or the like can be applied. .

For example, the thickness of the film is preferably 〇 丨〇 丨〇 丨〇, and preferably 0.1-1 μm. If the film thickness is less than 001 μm, the electrical resistance of the film becomes unstable, and if the film thickness exceeds 10 μm, the close adhesion to the base materials 45, 46 may not be achieved. The surface resistivity (value) is not particularly limited, and the surface resistivity can be appropriately selected according to a specific application requirement. For example, the surface resistivity required by the household/t may be 5,000 Ω/square or less' and preferably the side (1) square or less and preferably 15 Å/square or less. If the surface resistivity (value) exceeds 5000 Ω/square, the response characteristics at the time of information input can be degraded. For example, the surface resistivity can be measured according to m κ6911, ASTM D257 or the like. The coating method for coating the conductive polymer is not specifically-, "team, 适当 rpg, suitably selected from any known method, For example, spin coating, roll coating, dip coating, gravure coating, curtain coating, dye coating, spray coating, doctor blade, coating, (four) coating or the like.

In the touch panel 40D, a conductive polymer is formed on the fixed substrate, and an ITO film 43 is formed on the operation side substrate 12. Therefore, unlike the touch panels 10, 40A, 4B, 4〇c described above, the touch panel 4〇d • cannot be bent with the curved region 16 as a supporting point. The touch panel 40D is advantageous because the IT 〇 film 43 on the fixed side substrate 取代 is replaced by a conductive polymer, the durability of the touch panel 4 〇 D can be improved, and at the same time, the ITO film 43 A pale yellow tint can be used to correct the blue tint of the conductive polymer. As described above, for the touch panel of the present embodiment, the curved region 16 defining the two input operation regions 14, 15 can be freely bent, and therefore, when the touch panel is used as a support point with a curved region 16 Repeated bending of 129956.doc 1375168 in one of the ends of the control panel toward or away from the other end of the touch panel prevents stress from being concentrated in the curved region 16. Therefore, it is possible to provide a touch panel which can be repeatedly bent and has high durability and excellent electrical connection reliability. The present invention is by no means limited to the embodiments described above, but may be practiced in various modifications without departing from the scope of the invention. Although in the present embodiment, the PETs 45, 46 are applied to the substrates u, 12, it is also possible to use, for example, a limestone glass having a thickness of ~7-1.8 mm as a fixed side substrate. In this case, by dividing the blade of the curved portion 16 of the corresponding base material into a part, the strength of the touch panel can be increased without impairing the bending ability of the touch panel.
