Field of the Invention The present invention relates to a transparent touch panel and a method for fabricating the same, and a transparent touch panel for linearity that can improve position detection by annual weight. And its manufacturing method. [Background of the Invention] The display device is widely used in a display device such as a liquid crystal display device, and has a 10-fold stack of touch panels and is touched with a finger or a pen, thereby being able to specify a position, and is currently widely used. The resistive film is disposed opposite to the touch panel of the resistive film type. When using a pen to touch a high-resolution, high-precision display surface, the detection of the touch position must also be high-precision. Fig. 12 shows the construction of a transparent touch panel of an analog resistive film type in 15 cases. The lower resistor 104 and the upper resistor 108 are stacked such that a spacer 109 having a dot shape or the like is interposed between the resistive film 102 and the resistive film 1〇6, and the lower portion of the electrode 103 and the electrode 103 of the first electrode are in the direction of the upper resistor 1〇8. The direction of the electrodes 1〇7 is orthogonal, and the peripheral portion is followed by the adhesion layer 110 such as a double-sided tape, and the lower crucible resistor 104 is formed on the transparent insulating substrate 1〇1 such as a glass plate to form a tantalum oxide. a transparent resistive film 102 composed of 2 〇 (IT〇) or the like and a pair of parallel electrodes 103 formed of a silver paste or the like, and the upper resistor 1 〇 8 is formed of a transparent flexible insulating substrate 105 such as a polyester film. Next, the same resistance film 106 and electrode 107 as described above are formed. Further, the connection of the electrode 103 and the electrode 1〇7 to the external terminal is usually by the lower side. The 卩 resistor 104 or / and the upper resistor 1 〇 8 are provided with a surround wiring ηι, etc. 5 200915158. Figure 13 shows the principle of detecting the touch position of the transparent touch panel. Pressing any point p from the upper resistor 108 with a finger or a pen, and bringing the two resistive films H)6 and the resistive film 1 () 2 to point P, if the upper resistor is applied with 5 voltage and not When a voltage is applied to the lower resistor 104, the resistive film 106 of the upper resistor 1〇8 generates a potential gradient in the X-axis direction, and generates a voltage εχ which is divided to a point P on the resistive film 106 of the upper resistor 108, and the voltage is ~ It can be detected from the divided output 112 of the lower resistor 104. If the coordinates of the point P are set to (X, y), the distance between the electrodes of the upper resistor 1〇8 is set to L1, and the voltage between the electrodes 107 is set to E, then according to ex/E = x /L, Relationship, you can find the point ρ2 χ coordinates from the voltage ex. Further, if a voltage is applied to the lower resistor 104 and a voltage is not applied to the upper resistor 1〇8, a voltage is applied to the point ρ on the resistive film 102 of the lower resistor 104, and the voltage 5 can be divided from the upper resistor 108. The output terminal 113 detects. If the distance between the electrodes 1〇3 of the lower resistor 15 1〇4 is L2 and the voltage between the electrodes 103 is set to E, the point P2y can be obtained from the voltage ey according to the relationship of ey/E = y/L2. . The double-sided tape is placed in the frame area of the display device and hidden in the frame. However, when the frame is pressed, the upper resistor and the lower resistor are joined to each other and the input is mistaken. In order to prevent erroneous input, the double-sided tape is disposed inside the double-sided tape. 20 Insulation layers are also known. Japanese Laid-Open Patent Publication No. Hei 8-241646 discloses that an insulating layer having a thickness which is thinned toward the inside is disposed on a pivotal region adjacent to the inner side of the adhesive layer such as a double-sided tape, and it is pointed out that if an insulating film of uniform thickness is disposed, When the pen is slid in the vicinity of the insulating film, the resistive film is damaged by locally applying a strong pressure by the inner corner of the insulating film 200915158, and the conductivity or uniformity is impaired. If the thickness of the insulating film is thinned toward the inner side, Since the strong pressure is not locally applied by the inner corner portion of the insulating film, the upper resistive film is not damaged. Japanese Laid-Open Patent Publication No. Hei 8-241646. The conventional structure is such that a frame is provided in the upper portion of the display device frame, whereby the pen can be prevented from being input by the pen. Recently, since the thickness of the machine has been reduced, the structure of the entire touch panel has been removed on the surface by eliminating the upper frame. At this time, the upper resistor and the lower resistor are respectively covered by the insulating resist film to ensure insulation, and the insulating resist is used. An adhesive layer is formed on the film to bond the two members. [Explanation] According to the invention, in a touch panel having no frame on the upper periphery of the ridge, it is necessary to have resistance to pen input. 15 20 保持 提供 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - #(四) and having a positive U opposite side; flexible; _ lower transparent substrate above and below the board, and ί part of the transparent resistive film, formed on the upper transparent base layer wall, (four) / material red cross (4) the flat opposite side; the upper substrate; the upper transparent resistive film end portion and the lower portion and the laminated interlayer insulating film are disposed on the upper transparent substrate from the adjacent stack wall to the inner side The upper surface of the above-mentioned 200915158 transparent resistive film includes: a certain film thickness region having a first width from the inner end of the laminated wall; and a gradient region located inside the predetermined film thickness region and from the inner end toward the outer side The thickness is approximately 〇 gradually increased until reaching the aforementioned certain film thickness area. Further, the insulating protective film constitutes a cantilever structure which changes elasticity with respect to the pressing force.

The transparent substrate 1 has a flexible PET film having a thickness of 200 / / m, and the thickness of the transparent resistive film 2 is about 2. 2 #m, the specific resistance is 300 Ω / □, and the upper substrate area of the panel is 90 mm x 45 mm. Hereinafter, the transparent substrate 1 will be referred to as an upper transparent substrate, and the transparent resistive film 15 2 will be referred to as an upper transparent resistive film. The upper transparent resistive film 2 is patterned into a rectangular shape of 70 mm×4 〇 mm and having orthogonal orthogonal edges by wet etching using a mask, and the central portion of the upper transparent resistive film 2 is transparent to the lower portion described below. The resistive film is opposite to each other and constitutes an action field. On the end portion of the rectangular transparent resistive film 2 adjacent to the pair of opposing rims, the silver (Ag) paste is screen-printed at a width of 2 mm L5 mm at a distance of 15 mm from the field of motion, and dried and hardened. The upper electrode 3 having a thickness of about 10 " m is formed, and the drawn wiring is also formed at the same time. Using a 200-mesh screen printing 16, from the upper electrode side to the upper electrode 3 and extending from the inner side 16 of the upper electrode 3 toward the inner side, the elongation (ASTM D638) is 25%. The textile-made polyester screen ink 200915158 was screen-printed and dried to 'harden to form an upper insulating resist film 4 having a film thickness of about 15 #m. When viewed in this state, the upper insulating resist film 4 has an inner end thickness of substantially 0' and a small drop from the inner end toward the outer side and a substantially uniform inclination of 5 degrees, and the thickness is gradually thickened, and the width is 80. The range of #m forms an inclined surface with an average gradient of 10 degrees. Further, the field is referred to as a gradient field or an inclined field, and a film thickness 丨5" a certain film thickness field exists on the outer side of the gradient field or the inclined field. The adhesive layer 5 was screen-printed and dried from the inner side of the distance-insulating anti-contact film 4 from the side of the 〇 2111111 to the outer side of the 〇 3 mm to the outer periphery, and the thickness of the adhesive layer after drying was 25 / / m. As shown in the first section, the crystallinity of the lower transparent f-resist film 6 is formed into a thickness of 0.2 m on the transparent substrate 7 having a thickness of 咖7 coffee and a lower portion of the glass plate. The pattern of the lower transparent film 6 is formed into a rectangular shape having orthogonal opposite sides by using a wet pattern of a mask, and a rectangular transparent resistive film is formed in addition to the field in which the electrode should be formed. 6 The insulating UV-curing resin is printed and called (4) to be hardened to protect the point separator 19 for erroneous input. Moreover, the typical point separator is 40, the height 7, and the hemisphere. , & On the end portion of the rectangular lower transparent resistive film 6 and the pair of the opposite long sides, the silver paste is sieved (10) with a wide buckle, and dried and hardened to form an electrode having a thickness of 10 # m. . Until the lower electrode 11 is covered and the position of 0.2 mm is extended toward the inner side of the electrode is + ^ ^ sentence. The polyester screen printing ink manufactured by Toyo Textile is screen-printed, and dried, hardened and formed to form a thickness of 200915158. The insulating resist film 18 is under the 15/m. The lower end of the lower insulation anti-film 18 is thicker at the inner end, and forms a less uneven and substantially uniform inclination toward the outer side, and gradually thickens the thickness, and forms an average gradient of 1 (degree) at a width of 80 hearts. Inclined surface. 5 As shown in Fig. 1C, the upper and lower transparent resistive films 2, 6 are opposed to each other, and the upper and lower substrates are placed below.

Even the action field 9 and the I-shaped wall LW If the distance is, for example, 1.5 mm, it is also difficult to prevent the pen 12 from automatically sliding the field 9 to the outside, X, because the height of the 4 transparent resistive film 2 on the laminated wall LW is fixed, so even if the pen U wants to press down the 5 layer wall LW 'The upper resistance age will not bend. If the front end of the pen η presses the action sheet or the area between the 9 and the laminated wall (4), the resistive film will bend at the steep angle of the steep mountain. The pen 12 is closer to the laminated wall LW, and the bending is performed. The steeper the degree will be, the bending of the steep angle will cause cracks on the resistive film, etc., and it will be the cause of the increase in local resistivity. 1 〇 (4) The linearity of the resistor is required in the control panel, and the specification must be a linear value defined as 1.5. Below %. {(Measurement voltage Ex(y)m - rational Voltage Ex(y)t) / interelectrode voltage E} * 100 (%) In order to test the bending durability, there is 1.5 mm (evaluation test 1) and 1. 〇mm (evaluation) from the inner end 16 15 of the upper electrode 3 In the case of the test 2), the sliding test was carried out with a load of 4_9 N (5 〇〇 gf) using a POM pen of the front end 遍8 in a direction parallel to the upper electrode 3 over a length of 30 mm. The linear value is 5.6 〇 / 〇. In the evaluation test 2, the linear value of the sliding temple is 3 5%, and the 20 cannot be called the practical bending durability. The inventor believes that 'the upper transparent resistance is supported from the lower side. The insulating protective film of the cantilever structure of the film extends from the laminated wall structure to the inner side to the inner side to suppress the upper transparent resistive film from being bent at a corner of the laminated wall to a steep angle. The insulating protection of the cantilever structure is made to be insulated. The anti-money film was extended to the sample of Example 2 of the inner 12 200915158 and the characteristics were investigated. Example 2 5 10 15 20 The difference from the example i is that the upper insulation resistance (4) 4 is formed as indicated by the broken line in the figure, until the distance from the upper electrode 3, the inner end of the money ^ followed by the inner position. Above (four) The insulation resistance _4 is a thickness of about Wm in a certain film thickness region, and the thickness of the inner end is substantially 〇, and the inclination is small toward the outer side and is substantially uniform, and the thickness is gradually thickened, and the width is m. The gradient field forms an inclined surface of the average gradient position. The evaluation of the bending (four) longness is carried out in the same manner as in Example 1. The evaluation test 2 ° in the evaluation 4 test 1 shows that the linear value reaches the hungry when the number of sliding times _ , 2, the fabric please ^ her example (4) durability will be improved, - the general idea is hinted = the effectiveness of the beam structure, however, #日丁心豸... thinks... called practical bending durability. ^ The right upper insulating resist film 4 toward the action collar can be moderated to the upper portion of the corner wall of the laminated wall Lw. However, the upper insulation resistance, the inner end of the steep angle is allowed, and the Japanese riding _ 丨Life is not ^, not the bending at the steep angle of the resistive film. If I; I: the displacement of the front end of the beam at the force F is expressed as ^ right, the relative elastic coefficient c is too strong, the same as # ^ Z, 彳 is generally considered to be too large ~ Γ thick film thickness is too thick And the gradient of the gradient gradient gradient, /', shrinks - the thickness of the film thickness is reduced and reduced: the thickness of the film is made softer and then the inner end is recorded. == = change the bomb (four), structure, and from the bottom == Resistive film. Even if the material 佶 is conformed to the same type of material as σ 卩 transparent/insulating resist, only 13 200915158 is thinned compared to the thickness of the general upper insulating resist film, the angle of the gradient portion at the inner end is reduced' and A softer cantilever beam structure can be formed. When the insulating property is insufficient, the auxiliary insulating resist film may be laminated on the insulating protective film, and the flexible upper transparent substrate and the cantilever structure may be sandwiched by the upper transparent electric resist film, thereby suppressing The crack of the upper transparent resistive film is generated. 10 15 20 Figure 3 shows the basic structure. The upper transparent resistive film 2 is formed on the lower surface of the upper transparent substrate 1, and the upper electrode 3 is formed on the end portion thereof, and the insulating protective film 10 is extended from the outer side to the upper electrode 3 to the inner side, and is formed in a transparent portion with a certain width. The lower surface of the resistive film 2. The insulating protective film 1 is formed by the width dl from the inner side 钿丨6 of the working electric field, and the width d2 from the inner end Π to the outer side constitutes a gradient field or an inclined field in which the thickness gradually increases. On the lower surface of Yulin Protector, the upper insulating anti-slip film 4, the adhesive layer 5, and the lower insulating anti-remaining film (8) are laminated to cover the upper electrode 3' and the _LW and the lower transparent substrate 7. Right will be on. The large sigh of the inner side surface 16 of the p-electrode 3 to the inner side wall surface of the laminated wall (10) is d 3 ', and the width d4 of the insulating __ from the inner side of the laminated wall read to the inner side will constitute d4 = dl - (Π, η and equivalent The beam portion of the cantilever beam structure; the extension width d4 towel, minus the width of the gradient field or the width of the inclined field d2', that is, d4 - H9 Ac ^ - ^ - d5 is a certain thickness field, and has a 疋 elastic coefficient The plate spring ▼ is similar.

At the same time, the spring force of the inner front end is weak and can easily allow bending. , 'The spring force is from The inner front end gradually increases toward the outer side. 14 200915158 If the inner side of the insulating protective film ίο is attached, έ t 士+/_, _

The gradient field of the insulating protective film 10 or the spring characteristic of the inclined field is changed according to the gradient angle. The insulating protective film 1 can be formed by screen printing or inkjet printing, and the screen printing system allows the ink to be loaded on the screen printing. On the plate, the ink is pushed out and printed by the rubber roller under the screen. Since a part of the ink to be ejected remains on the screen printing plate, the amount of ink at the printing end portion is reduced, and the thickness of the printing film gradually becomes thicker from the finished printing end face toward the inside, and a uniform film is formed after a certain distance. thick. The thickness of the printing surface is changed according to the direction of movement of the rubber roller. In order to form a certain gradient in a stable manner, a gradient field is generated in parallel with the moving direction of the rubber roller, and the gradient angle and width of the gradient field are used. The combination of the rubber roller angle, the rubber roller speed, the mesh of the screen printing plate, the viscosity of the ink, the viscoelasticity of the ink, etc., and the width of the gradient field is designed to be about lmrn. The outer peripheral portion of the insulating film 20 is printed to be larger than the size of the upper electrode. Thus, a film having no drip screen printing and uniform film thickness can be formed. In inkjet printing, the gradient angle adjustment of the gradient field is performed by controlling the number of printing times and the printing interval. As the material of the insulating protective film 10, an organic film such as an acrylic resin, a polyester resin, a 15 200915158 guanamine resin, a polyolefin resin, an amino phthalate resin, a polyamide amide resin, or a ruthenium resin can be used. Generally, the elongation of the insulating protective film (ASTMD638) is 10% to 40%, and the elongation of the insulating protective film is preferably the above. Further, the insulating protective film 10 may have a single layer structure, and may also be a laminate of a plurality of layers. Moreover, the insulating protective film may also function as an insulating resist film. The insulating protective film 10 can be formed by various printing methods such as screen printing, gravure printing, and letterpress inkjet printing. If a mask or the like is used, it can be formed by a sputtering method or a vapor deposition method. According to the above investigation, the sample of Example 3 was prepared, and the sample was formed on the upper transparent resistive film 2 to form an insulating protection 臈1〇 which restricted the film thickness to a thin film thickness of 10 and narrowed the angle of the gradient region. The upper insulating resist film 4 is formed. Example 3 As shown in Fig. 4A, the upper substrate is a PET (poly-p-dicarboxylic acid) which is used on the upper transparent substrate 15 1 of the crystalline IT0 film (indium tin oxide film) on which the upper transparent resistive film 2 is formed on one surface. Ethylene diester) film (Eyreck film manufactured by Nitto Denko). The upper transparent substrate 1 has a thickness of 200#!!! and has a flexible PET film. The upper transparent resistive film 2 has a thickness of about 2.2#m, a resistivity of 3〇〇Ω/□, and an average upper substrate area of the panel. It is 9〇mmx45mm. By using the wet pattern of the mask, the upper transparent resistive film 2 is patterned into a rectangular shape having a shape of 20 mm to 40 mma having orthogonal sides, and a rectangular transparent resistive film 2 and a pair of opposite sides ( The short side) is adjacent to the end portion, and the silver paste is screen-printed at a width of 15111111 at a distance of 1.5 mm from the action area, and dried and hardened to form an upper electrode 3 having a thickness of l〇//m.

The thickness of the film thickness of the insulating protective film 10 is 5# m, and the thickness of the inner end is substantially 0, and the outer side is formed with a small drop and a substantially uniform inclination angle and gradually becomes thicker, and the inner end 17 is further The average gradient of the 0.1 mm sloped field is 3 degrees. 1 〇 until the inner side 16 of the upper electrode 3 has an inner side of 0.2 mm, the polyester-based insulating resist film 4 having an elongation of 20% is applied by screen printing, and dried and hardened, and the insulating resist film is further removed. The thickness of the film thickness region of 4 is 15 //m, and the average gradient 15 20 of the inclined surface formed in the gradient region of the width is 10 degrees. By the screen printing, the adhesive layer 5 was applied from the outer side to the outer periphery of the insulating film at a distance of 0.2 mm to 0.3 mm, and dried, and the film thickness of the adhesive layer 5 was 25 / / m. In this configuration, dl = 1 3 mm, d2 = 0.1 mm, d3 = 0.2 mm, d4 = 1.1 mm, and d5 = 1.0 mm. As shown in Fig. 4B, the crystalline ιτ〇 film of the τ-part transparent resistive film 6 was formed into a thickness of 0.2 Å by a sputtering method on a transparent substrate 7 having a thickness of 〇7111111 and a lower portion of the glass plate. The pattern of the lower transparent resistive film 6 is formed into a rectangular shape by using a wet pattern of a mask. Further, in addition to the field in which the electrode should be formed, an insulating ultraviolet curable resin screen is formed on the rectangular lower transparent resistive film 6. The printing is made into a mixture, and the uv is hardened (4) into a dot spacer 19 for preventing erroneous input. Further, a typical dot spacer is a hemispherical shape having a diameter of 4 -, a height of 7 /zm 17 200915158, and a density of 1 mm. form. The silver paste was screen-printed at a width of 1.5 mm on the end portion of the rectangular lower transparent resistive film 6 adjacent to the pair of opposite sides (long sides), and dried and hardened to form a thickness of 10/m. Lower electrode 11. The polyester screen ink manufactured by Toyobo Co., Ltd. was screen-printed until it covered the lower electrode 11 and protruded toward the inner side 5 of the electrode by 0.2 mm, and dried and hardened to form a lower insulation resistance of 15/m. Corrosion film 18. The lower insulating resist film 18 has an end portion having a thickness of substantially zero, and has a small drop and a substantially uniform inclination toward the outside, and gradually thickens the thickness, and forms an average gradient 10 in a gradient region of a width of 10 degrees 80/m. The slope of the degree. As shown in FIG. 4C, the upper and lower transparent resistive films 2, 6 are opposed to each other, and the upper substrate and the lower substrate are positioned such that the upper electrode 3 and the lower electrode 11 are orthogonal, and the opposite conductive film is adhered to both ends of the end. The FPC (Flexible Printed Circuit) is inserted between the upper and lower substrates and thermocompression bonded, thereby making an analog type transparent touch panel. Evaluation test 1 and evaluation test 2 were carried out. In the evaluation test 1, the linear value was 0.5% in the same manner as in the case of the sliding number of 10,000, and the linear value was also 0.7% in the number of sliding times of 100,000. In the evaluation test 2, the linear value was produced at the time of the sliding number of 100. The same 0.5% is used, and when the number of sliding times is 10000, 20 is also 0.7%. Compared with Example 1, the bending durability is improved, and the bending durability is sufficiently resistant. Attempts have been made to change the material of the insulating protective film and to substantially shorten the length of the self-laminated wall. Example 4 As shown in Fig. 4, the upper 18 200915158 transparent resistive film 2 having the flexible upper transparent substrate 1 was patterned, and the upper electrode 3 was formed thereon 1.5 mm apart from the field of motion. This is the same as in Example 3. From the outer side of the upper electrode 3 to the inner side surface 16 of the upper electrode 3 from the inner side of the upper electrode 3, the inner diameter of the upper electrode 3 is within 4 mm, and the elongation (ASTMD638) is 15%. It is dried and hardened to form an insulating protective film 1〇. The thickness of the film thickness of the insulating protective film 1 is 5 # m, and the average gradient of the gradient field of 0.1 mm from the inner end 17 is 3 degrees. Until the inner end surface 16 of the upper electrode 3 has an inner side of the im.immi, |f.., the insulating anti-remaining film 4 is formed by screen printing at a film thickness of 14/zm and dried, and dried and hardened. The adhesive layer 5 is formed by screen printing and dried. In the structure L, ' dl — 〇 .4mm ′ d2 = 0.1mm, d3 = 0.1mm, d4 = 0.3mm, d5 = 〇 2mm. The lower transparent substrate 7 is the same as in the example 3. The upper transparent substrate and the lower transparent substrate are bonded and thermocompression bonded, and an analog transparent touch panel is formed. 15 Evaluation test 1 and evaluation test 2 were carried out. In Evaluation Test 1, the linear value reached 3.6% at a sliding I of 10,000, and in the evaluation test 2, the linear value reached 2.1% at a sliding number of '100. Compared with Example 2, the bending durability would be Improvement, it can be seen that the thinned insulating protective film has a film thickness in a certain thickness field and reduces the inclination angle of the gradient field, but it is not resistant to practical bending and durability. It is considered that the film thickness field has a short extension width d5 from the laminated wall LW and the improvement in bending durability is small. In Example 3, the insulating resist film 4 of Example 1 was replaced by a laminate of the insulating protective film 1 and the insulating resist film 4, and the case of using a single-layer insulating protective film which restricted the thickness was also examined. 19 200915158 Example 5 As shown in Fig. 5, in the same manner as in Example 3, 'the transparent resistive film 2 on the upper surface of the crystalline ITO film having the flexible upper substrate 1 is patterned" and is 1.5 from the field of motion. The upper electrode 3 is formed in mm.

The film is 1 inch. The insulating protective film 1 疋 10 has a film thickness of 10 // m in the field of film thickness, and the average gradient in the gradient region is up to 6 degrees until 0.1 mm from the inner end 17 , and the insulating resist film 4 is not formed. And the adhesive layer 5 is formed on the insulating protective film 1 by screen printing and dried. The lower transparent substrate 7 is the same as in the example 3. The upper and lower transparent resistive films 2, 6 15 are opposed to each other, and the upper substrate and the lower substrate are positioned such that the upper electrode 3 and the lower electrode 11 are the fathers, and the FPC (flexible printed circuit) which has been adhered to the opposite side conductive film on both sides of the end portion Inserting the ± substrate between the substrates for thermal crimping, thereby forming an analog transparent touch panel. The evaluation test was carried out and the evaluation test 2 was carried out. In the evaluation test 4, the linear value is 5% of the egg at the time of sliding 20 times, and the linear value is _ when the one is slipped. In the evaluation test 2, the linear value is at the sliding - the number of people is 100. It is the same as 0 5% at the time of manufacture, and it is also a slap in the case of the number of times of sliding. Compared with Example 3, although the durability of f-curve is slightly lowered, substantially equivalent bending durability can be obtained. The insulating protective film raw material is not limited to the one described in the above-mentioned 20 200915158, and a sample in which the insulating protective material is changed. Example 6 As shown in Fig. 6, the upper transparent resistive film 2 having the flexible upper transparent substrate 1 was patterned in the same manner as in Example 3, and the upper electrode 3 was formed in parallel. The elongation (ASTM D638) was 30% and a material of 25% of a specific diluent was added to ten chemically produced urethane screen inks as a raw material for the insulating protective film. Using a screen printing plate of 460 mesh, from the side I of the upper electrode 3 to the inner side of the inner side end 16 of the electrode, there is a range of 1.3 mm inside, and the insulating material is screen-printed and dried and hardened. The insulating protective film 10 is formed. The thickness of the film thickness of the insulating protective film 10 is about 3 mm, and the average gradient in the gradient region is 31 „1 „1 from the inner end 17 is 3 degrees, and the insulating protective film is the same as in the example 3.

In the evaluation test 2, the linear value is in the sliding temple. The same 0.5% at the time of manufacture is also 0_8/° when the number of slides is 1 ,. Compared with Example 3, although the bending durability is slightly lowered, it is available. The bending durability of the same layer is considered to be slightly deteriorated due to the difference in material properties of the insulating protective film. Example 7 1〇 As shown in Fig. 7, the flexible upper transparent substrate 23 was made of (1/4) λ phase difference-decreasing stencil resin. An amorphous ιτο film (indium tin oxide film) of a transparent resistive film is formed on the upper transparent substrate 23 by patterning, and patterned into a rectangular transparent resistive film 2, and further in a rectangular shape. On the end portion of the transparent resistive film 2 adjacent to the pair of opposite sides (short sides), the silver paste is screen-printed at a width of 15 丨 5111111, and dried and hardened to form a thickness of about 1 〇 " Upper electrode 3. A special dilution of 25 〇/〇 material will be added to the polyester screen ink manufactured by Seiko as the insulating protective film material.

The τ electric view is formed and the direct drying is hardened. Further, (4) the edge is resistant to Zhao Qi bribe printing, and it is dried and hardened to form an insulating resist film 8 . An Fpc (flexible printed circuit) having an opposite-side conductive film adhered to both ends of the end portion is inserted between the upper transparent substrate 23 and the lower transparent substrate, and is thermally bonded, and a basic analog type transparent touch panel is formed. Adhesive layer 15 is adhered to the lower transparent substrate 2, and an optical isotropic PC (polycarbonate) plate 26 is adhered thereto, and the adhesive layer polarizing plate 22 is reduced to the upper transparent substrate 23.

Evaluation test 1 and evaluation test 2 were carried out. In the evaluation test, the linear value is the same as 0.5% at the time of the sliding, and the linear value is also 〇8% at the sliding number of 100,000. In the evaluation test 2, the linear value is in the sliding 23 200915158 ★, 100 The time is 0.5% the same as that at the time of manufacture, and is also - when the number of slides is 1 GGG0 - the bending durability equivalent to that of Example 5 can be obtained. Further, a sample in which a hard coat PET film was adhered to the upper transparent substrate of Example i through an adhesive layer was also prepared. Example 8 As shown in Fig. 1, the transparent resistive film 2 having the flexible upper transparent substrate 1 was patterned in the same manner as in Example 1, and the upper drain 3 was formed thereon. A 200-mesh screen printing plate is used until the inner end surface 16 of the upper electrode 3 has a side of 〇_2 mm, and the polyester screen printing ink manufactured by Toyobo is screen-printed, dried, and hardened. Insulation resistance 10 etching film 4. The thickness of the film thickness of the insulating resist film 4 is 15/zm, and an inclined portion having an average gradient of 10 degrees at a substantially uniform angle from the inner end to the width of 80 in the gradient region of m is formed on the insulating resist film. Adhesive layer 5 is formed on 4. The lower transparent substrate 7 was formed in the same manner as in Example 1, and the upper transparent substrate and the lower transparent substrate were bonded together and thermocompression bonded. 15 is the same as in Example 6, as shown in Fig. 6, through the optical adhesive layer 21, the hard coating on the outermost surface and the image printed on the inner frame portion and the thickness of 125 #爪的PET (polyethylene terephthalate) Ester) The meal 20 is adhered to the upper transparent substrate and is made of a decorative analog transparent touch panel. The evaluation test of the bending durability and the evaluation test 2 were carried out in the same manner as in Example 1. In Evaluation Test 1, the linear value reached 4.8% at the time of 1潸00〇, and the linear value reached 46% in the evaluation test 2, compared with Example 1, in the evaluation test. In 1 case, although the bending durability is slightly changed to the cover 0, it is not yet known as the durability of the practical f oil. In the evaluation (4), the 2" curvature durability ratio 1 is worse. - The hard coating is considered to be less helpful. In addition to the improvement of f-resistance 24 200915158, a sample of an insulating protective film was formed by inkjet printing instead of screen printing. Example 9 As shown in Fig. 4, there will be a flexible upper transparent substrate. The upper five transparent resistive films 2 on the crucible are patterned, and the upper electrode 3 is formed thereon. An acrylic acid black ink having an elongation (ASTM D638) of 15% is used, and inkjet printing by 1440 DPI is used.

In the evaluation test 2, the linear value is 相同·5% which is the same as that at the time of sliding 25 200915158, and 0.7% when the number of slides is 10000. The bending durability equivalent to that of Example 3 was obtained. When the shape of the insulating protective film (4) is considered to be small, the performance difference depending on the manufacturing method is small.
