Description

静電容量型タッチパネルアセンブリの製造方法及びこれを備えた表示装置Method of manufacturing capacitive touch panel assembly and display device provided with the same
　本発明は、静電容量の変化を利用して入力操作を検知するための静電容量型タッチパネルアセンブリの製造方法に関する。また、本発明は、このような静電容量型タッチパネルアセンブリを備えた表示装置に関する。 The present invention relates to a method of manufacturing a capacitive touch panel assembly for detecting an input operation using a change in capacitance. The present invention also relates to a display device provided with such a capacitive touch panel assembly.
　例えば、タッチパネル式液晶表示装置は、液晶表示手段と、この液晶表示手段の表面側に配設されたタッチパネルアセンブリとを備え、このタッチパネルアセンブリとして、静電容量型タッチパネルアセンブリを用いたものが知られている（例えば、非特許文献１参照）。 For example, a touch panel liquid crystal display device includes liquid crystal display means and a touch panel assembly disposed on the surface side of the liquid crystal display means, and as this touch panel assembly, one using a capacitive touch panel assembly is known. (See, for example, Non-Patent Document 1).
　このような静電容量型タッチパネルアセンブリは、静電容量型タッチパネルと、このタッチパネルの表面側に配設された外装部材とを備え、外装部材が透明プラスチック、透明ガラスなどから形成されている。静電容量型タッチパネルは、電気的絶縁性を有する樹脂シートを備え、この樹脂シートの片面にマトリックス状に第１導電パターン（例えば、横方向の位置を検出するためのパターン）が設けられ、その他面にマトリックス状に第２導電パターン（例えば、縦方向の位置を）検出するためのパターン）が設けられ、これら第１及び第２導電パターンに微弱の電流が供給される。 Such a capacitive touch panel assembly includes a capacitive touch panel and an exterior member disposed on the surface side of the touch panel, and the exterior member is formed of transparent plastic, transparent glass, or the like. The capacitive touch panel includes a resin sheet having electrical insulation, and a first conductive pattern (for example, a pattern for detecting a lateral position) is provided in a matrix on one side of the resin sheet, and the other A second conductive pattern (for example, a pattern for detecting the position in the vertical direction) is provided in a matrix on the surface, and a weak current is supplied to the first and second conductive patterns.
　このような微弱電流の供給状態において、タッチパネルアセンブリの表面（外装部材の表面）を指などで入力操作すると、タッチパネル表面の電荷が変化し、例えば、第１導電パターン側の電荷の状態を検知して横方向の位置を検出することができ、また第２導電パターン側の電荷の変化を検知して縦方向の位置を検出することができる。 When the surface of the touch panel assembly (the surface of the exterior member) is subjected to an input operation with a finger or the like in such a weak current supply state, the charge on the touch panel surface changes, for example, the charge state on the first conductive pattern side Thus, the position in the lateral direction can be detected, and the change in charge on the side of the second conductive pattern can be detected to detect the position in the vertical direction.
　このような静電容量型タッチパネルアセンブリでは、タッチパネル及び外装部材がプレート状に形成されているために、外観意匠のデザインの自由度が少なく、また入力操作面もタッチパネルアセンブリの上面のみとなって操作性に優れてなく、操作性の面での改善が望まれている。また、外装部材が透明ガラスである場合、重量が重く、割れやすいという問題があり、また透明プラスチックである場合、単品毎に切削にて生産されており、生産性が低くなるという問題がある。 In such a capacitive touch panel assembly, since the touch panel and the exterior member are formed in a plate shape, the degree of freedom in design of appearance design is small, and the input operation surface is also operated only on the upper surface of the touch panel assembly It is not excellent in quality, and improvement in terms of operability is desired. Further, when the exterior member is transparent glass, there is a problem that the weight is heavy and it is easily broken, and when it is a transparent plastic, it is produced by cutting for each single product, and there is a problem that productivity is lowered.

　次に、図４とともに図５～図１５を参照して、上述した静電容量型タッチパネルアセンブリ８の製造方法について説明する。尚、以下の説明においては、図１～図３と同じ部材には同一の参照番号を付して説明する。 Next, a method of manufacturing the above-described capacitive touch panel assembly 8 will be described with reference to FIGS. 5 to 15 together with FIG. In the following description, the same members as those in FIGS. 1 to 3 are described with the same reference numerals.
　図４において、静電容量タッチパネルアセンブリ８を製作するには、インサート成形を行うに先立って、外装カバー１４（カバーフィルム）及び静電容量型タッチパネル１０（タッチパネルフィルム）を製作する。外装カバー１４を製作するには、透明乃至半透明のカバー用フィルム材料３２の片面に印刷を施して印刷層２６を形成する（カバー用フィルム材料印刷工程Ｓ１）。例えば、カバー用フィルム材料３２としては、上述したように、例えばポリエチレンテレフタレート（ＰＥＴ）のフィルムなどを用いることができる。このカバー用フィルム材料印刷工程Ｓ１では、図５に示すように、外装カバー１４の天壁２０よりも幾分大きい略矩形環状の所定領域３４に、例えば、黒色、白色、メタリック調などの印刷を施し、このように印刷を施して所定領域３４の中央部に透明乃至半透明の矩形状の開口領域２４を形成し、この開口領域２４が外装カバー１４の窓（即ち、液晶表示装置２の表示窓５）として機能する。 In FIG. 4, in order to manufacture the capacitive touch panel assembly 8, the exterior cover 14 (cover film) and the capacitive touch panel 10 (touch panel film) are manufactured prior to performing insert molding. In order to manufacture the exterior cover 14, printing is performed on one side of the transparent to translucent cover film material 32 to form the print layer 26 (cover film material printing step S <b> 1). For example, as the cover film material 32, as described above, for example, a film of polyethylene terephthalate (PET) can be used. In the cover film material printing step S1, as shown in FIG. 5, for example, printing of black, white, metallic tone, etc. is performed on a substantially rectangular annular predetermined area 34 which is somewhat larger than the top wall 20 of the exterior cover 14. And print in this manner to form a transparent to semitransparent rectangular opening area 24 at the center of the predetermined area 34, and this opening area 24 is a window of the exterior cover 14 (that is, the display of the liquid crystal display device 2). Act as a window 5).
　この実施形態では、一つのカバー用フィルム材料３２に、間隔をおいて８箇所に所定領域の印刷層２６を形成しているが、このカバー用フィルム材料３２の大きさに対応した適宜の数を一度に印刷するようにすることができる。尚、このような印刷層２６は、スクリーン印刷、オフセット印刷などの適宜の印刷方式によって印刷することができる。 In this embodiment, the print layer 26 of a predetermined area is formed at eight places at intervals in one film material 32 for a cover, but an appropriate number corresponding to the size of the film material 32 for a cover may be used. It can be made to print at one time. Such a printing layer 26 can be printed by an appropriate printing method such as screen printing or offset printing.
　次に、カバー用フィルム材料３２に抜き加工を施して所定領域３４を含むカバーフィルム片３６を形成し（カバーフィルム抜き工程Ｓ２）、このように形成したものが開口領域２４を有するカバーフィルムとなる。 Next, the cover film material 32 is punched to form the cover film piece 36 including the predetermined area 34 (cover film extraction step S2), and the thus-formed cover film becomes a cover film having the opening area 24. .
　このカバーフィルム抜き工程Ｓ２においては、例えば、プレス型（図示せず）などを用いた型抜き加工で行うことができ、図５に一点鎖線４０で示すように型抜き加工することによって、図６に示すカバーフィルム片３６が形成される。 In this cover film removing step S2, for example, it can be performed by die cutting using a press die (not shown) or the like, and by die cutting as shown by a dashed dotted line 40 in FIG. A cover film piece 36 shown in FIG.
　その後、図６に示すカバーフィルム片３６にフォーミング加工を施して図７に示す第１中間カバーフィルム５２を形成する（カバーフィルムフォーミング工程Ｓ３）。このカバーフィルムフォーミング工程Ｓ３においては、カバーフィルム片３６を所定温度範囲にプレヒートし、このように加熱したカバーフィルム片３６をプレス型（図示せず）にセットし、プレス型によるフォーミング加工を施す。即ち、プレス型として凸状フォーミング金型及び凹状フォーミング金型を用い、これら両フォーミング金型の間にカバーフィルム片３６を介在させ、凸状フォーミング金型及び凹状フォーミング金型によってフォーミング加工を施し、かく加工することによって、図７に示す形状の第１中間カバーフィルム５２が形成される。このフォーミング加工は上記の熱プレス成形の他に真空成形、圧空成形、もしくはこれらの組み合わせにより加工することができる。 Thereafter, the cover film piece 36 shown in FIG. 6 is subjected to forming processing to form a first intermediate cover film 52 shown in FIG. 7 (cover film forming step S3). In the cover film forming step S3, the cover film piece 36 is preheated to a predetermined temperature range, and the cover film piece 36 thus heated is set in a press die (not shown) and subjected to a forming process using a press die. That is, a convex forming die and a concave forming die are used as a press die, and a cover film piece 36 is interposed between both forming dies, and forming is performed by the convex forming die and the concave forming die, By this processing, the first intermediate cover film 52 having the shape shown in FIG. 7 is formed. This forming process can be processed by vacuum forming, pressure forming, or a combination thereof in addition to the above-described heat press forming.
　この第１中間カバーフィルム５２は、上方に延びる立上り部５４（外装カバー１４の周側壁２２に対応する部分）と、この立上り部５４の上端部から内方に平面状に延びる平面状部５６（外装カバー１４の天壁２０に対応する部分）と、立上り部５４の下端部から外方に延びる環状フランジ５８とを有し、印刷層２６が設けられた所定領域３４は、立上り部５４及びこの立上り部５４に続く平面状部５６の外周縁部まで延びている。 The first intermediate cover film 52 has a rising portion 54 extending upward (a portion corresponding to the circumferential side wall 22 of the exterior cover 14) and a flat portion 56 extending in a planar manner inward from the upper end portion of the rising portion 54. The predetermined area 34 provided with the print layer 26 includes the rising portion 54 and the annular flange 58 extending outward from the lower end portion of the rising portion 54). It extends to the outer peripheral edge of the flat portion 56 following the rising portion 54.
　次に、図７に示す第１中間カバーフィルム５２にトリミング加工を施して不要な部分を除去して、図８に示す通りの第２中間カバーフィルム６０を形成する（カバーフィルムトリミング工程Ｓ４）。このカバーフィルムトリミング工程Ｓ４においても、カバーフィルム抜き工程Ｓ２と同様に、例えば、プレス型（図示せず）などを用い、このプレス型によって型抜き加工を第１中間カバーフィルム５２に施し、外方に延びる環状フランジ５８を除去することによって、図８に示す第２中間カバーフィルム６０が形成される。 Next, trimming processing is performed on the first intermediate cover film 52 shown in FIG. 7 to remove unnecessary portions, and the second intermediate cover film 60 as shown in FIG. 8 is formed (cover film trimming step S4). Also in the cover film trimming step S4, similarly to the cover film removing step S2, for example, using a press die (not shown) or the like, the first intermediate cover film 52 is die-cut by this press die, and outward The second intermediate cover film 60 shown in FIG.
　この第２中間カバーフィルム６０は、外装カバー１４とほぼ同じ形状に形成され、外装カバー１４の周側壁２２に対応する立上り部５４及びその天壁２０に対応する平面状部５６を有し、このようにして外装カバー１４（カバーフィルム）が形成される。 The second intermediate cover film 60 is formed in substantially the same shape as the exterior cover 14 and has a rising portion 54 corresponding to the circumferential side wall 22 of the exterior cover 14 and a flat portion 56 corresponding to the top wall 20 thereof. Thus, the exterior cover 14 (cover film) is formed.
　また、静電容量型タッチパネル１０は、外装カバー１４と略同様にして、例えば次のようにして製作することができる。静電容量型タッチパネル１０を製作するには、まず、透明乃至半透明のタッチパネル用フィルム材料６２に導電性パターンＰＴを形成する。この導電性パターンＰＴは第１及び第２導電性パターン１５，１７を含み、第１導電性パターン１５はタッチパネル用フィルム材料６２の片面に形成され、第２導電性パターン１７はタッチパネル用フィルム材料６２の他面に形成される（導電性パターン形成工程Ｓ５）。例えば、タッチパネル用フィルム材料６２としては、上述したように、例えばポリエチレンテレフタレート（ＰＥＴ）のフィルムなどを用いることができる。 The capacitive touch panel 10 can be manufactured in substantially the same manner as the exterior cover 14 as follows, for example. In order to manufacture the capacitive touch panel 10, first, the conductive pattern PT is formed on a transparent to semitransparent film material 62 for a touch panel. The conductive pattern PT includes the first and second conductive patterns 15 and 17. The first conductive pattern 15 is formed on one side of the touch panel film material 62. The second conductive pattern 17 is a touch panel film material 62. Formed on the other surface (conductive pattern forming step S5). For example, as the film material 62 for a touch panel, as described above, for example, a film of polyethylene terephthalate (PET) can be used.
　この導電性パターン形成工程Ｓ５では、まず、図９に示すように、このフィルム材料６２の片面の所定領域Ｒ（一点鎖線６６で囲まれた領域）に第１導電性パターン１５が形成される（図９～図１３において、第１導電性パターン１５の一部のみを示す）。図１０に示す様に、この第１導電性パターン１５には、マトリックス状に配列された多数の第１電極パッド１５Ｍと、複数個の第１接続端子１５Ｔと、複数個の第２接続端子１７Ｔと、第１電極パッド１５Ｍと接続端子１５Ｔとを接続する複数本の第１配線１５Ｌと、複数個の接続端子１７Ｔの各々に接続された複数本の第２配線１７Ｌａとが含まれ、これらは全て上述したような透明導電性材料で形成される。また、所定領域Ｒは領域Ｒａと領域Ｒｂとを有し（領域Ｒａと領域Ｒｂとの境界を点線６６ａで示す）、第１電極パッド１５Ｍは、領域Ｒａの実質上全域に形成され、第１及び第２接続端子１５Ｔ，１７Ｔは、領域Ｒｂの一端側に一列に配列されて形成される。 In the conductive pattern forming step S5, first, as shown in FIG. 9, the first conductive pattern 15 is formed on a predetermined region R (a region surrounded by a dashed dotted line 66) of one side of the film material 62 ( Only a part of the first conductive pattern 15 is shown in FIGS. As shown in FIG. 10, the first conductive pattern 15 includes a plurality of first electrode pads 15M arranged in a matrix, a plurality of first connection terminals 15T, and a plurality of second connection terminals 17T. And a plurality of first wires 15L connecting the first electrode pads 15M and the connection terminals 15T, and a plurality of second wires 17La connected to the plurality of connection terminals 17T, respectively, All are formed of the transparent conductive material as described above. The predetermined region R has a region Ra and a region Rb (the boundary between the region Ra and the region Rb is shown by a dotted line 66a), and the first electrode pad 15M is formed substantially throughout the region Ra. The second connection terminals 15T and 17T are arranged in a line on one end side of the region Rb.
　次に、所定領域Ｒの他面に第２導電性パターン１７が形成される（尚、図９及び図１０において、第２導電性パターン１７の一部を示す）。この第２導電性パターン１７には、領域Ｒａの他面側の実質上全域にマトリックス状に形成された多数の第２電極パッド１７Ｍと、第２電極パッドに接続された第３配線１７Ｌｂとが含まれ、これらは全て上述したような透明導電性材料で形成される。 Next, the second conductive pattern 17 is formed on the other surface of the predetermined region R (note that, in FIGS. 9 and 10, a part of the second conductive pattern 17 is shown). In the second conductive pattern 17, a large number of second electrode pads 17 M formed in a matrix over substantially the entire area on the other surface side of the region Ra and a third wiring 17 Lb connected to the second electrode pads are included. Inclusion, all of which are formed of transparent conductive materials as described above.
　次に、タッチパネル用フィルム材料６２の所定箇所に貫通孔ＴＨを形成し、これら貫通孔ＴＨに導電性材料を用いた充填印刷を施すことにより、第２配線１７Ｌｂと対応する第３配線１７Ｌｂとを電気的に接続する。また、第１及び第２接続端子１５Ｔ，１７Ｔにカーボン印刷を行うことにより、第１及び第２接続端子１５Ｔ，１７Ｔにカーボンインクを塗布する。このように、第１及び第２接続端子１５Ｔ，１７Ｔにカーボンインクを塗布することにより、第１及び第２接続端子１５Ｔ，１７Ｔがカーボンインクにより保護され、マイグレーション現象の発生が防止される。 Next, through holes TH are formed in predetermined places of the film material 62 for a touch panel, and filling printing using a conductive material is performed on these through holes TH, thereby forming the second wiring 17Lb and the third wiring 17Lb corresponding to the second wiring 17Lb. Connect electrically. Further, carbon printing is performed on the first and second connection terminals 15T and 17T to apply carbon ink to the first and second connection terminals 15T and 17T. As described above, by applying the carbon ink to the first and second connection terminals 15T and 17T, the first and second connection terminals 15T and 17T are protected by the carbon ink, and the occurrence of the migration phenomenon is prevented.
　尚、この実施形態では、シート状のタッチパネル用フィルム材料６２を用いているが、ロール状のタッチパネル用フィルム材料を用いるようにしてもよい。また、ここではタッチパネル用フィルム材料６２の片面に全ての電気的接続部（第１及び第２接続端子１５Ｔ，１７Ｔ）を形成する構成としているが、タッチパネル用フィルム材料６２の両面に電気的接続部を形成することもでき、この場合には第２接続端子１７Ｔと第２配線１７Ｌａとをタッチパネル用フィルム材料６２の他面に形成し、第２配線１７Ｌａと第３配線１７Ｌｂとを貫通孔ＴＨを介さずに直接的に接続させる構成とすれば良く、貫通孔ＴＨの形成は不要となる。 In this embodiment, the sheet-like touch panel film material 62 is used, but a roll-like touch panel film material may be used. Further, although here, all the electrical connection portions (first and second connection terminals 15T and 17T) are formed on one side of the film material 62 for touch panel, the electrical connection portions are formed on both sides of the film material 62 for touch panel In this case, the second connection terminal 17T and the second wiring 17La are formed on the other surface of the touch panel film material 62, and the second wiring 17La and the third wiring 17Lb are formed in the through holes TH. It may be configured to be directly connected without interposing, and the formation of the through holes TH is not necessary.
　次に、タッチパネル用フィルム材料６２に抜き加工を施してタッチパネルフィルム片６４を形成し（タッチパネルフィルム抜き工程Ｓ６）、このように形成したものがタッチパネルフィルムとなる。 Next, the touch panel film material 62 is punched to form a touch panel film piece 64 (touch panel film removing step S6), and the touch panel film formed in this manner becomes a touch panel film.
　このタッチパネルフィルム抜き工程Ｓ６においては、例えば、プレス型（図示せず）などを用いた型抜き加工で行うことができ、図９に一点鎖線６６で示すように型抜き加工することによって、図１１に示すタッチパネルフィルム片６４が形成され、第１導電性パターン１５は、このタッチパネルフィルム片６４の片面に存在し、第２導電性パターン１７は、その他面に存在する。 In this touch panel film removing step S6, for example, it can be performed by a die cutting process using a press die (not shown) or the like, and as shown by an alternate long and short dash line 66 in FIG. The first conductive pattern 15 is present on one side of the touch panel film piece 64, and the second conductive pattern 17 is present on the other side.
　その後、図１１に示すタッチパネルフィルム片６４にフォーミング加工を施して図１２に示す第１中間タッチパネルフィルム６８を形成する（タッチパネルフィルムフォーミング工程Ｓ７）。このタッチパネルフィルムフォーミング工程Ｓ７においては、タッチパネルフィルム片６４を所定温度範囲にプレヒートし、このように加熱したタッチパネルフィルム片６４をプレス型（図示せず）にセットし、プレス型によるフォーミング加工を施す。即ち、プレス型として凸状フォーミング金型及び凹状フォーミング金型を用い、これら両フォーミング金型の間にタッチパネルフィルム片６４を介在させ、凸状フォーミング金型及び凹状フォーミング金型によってフォーミング加工を施し、かく加工することによって、図１２に示す形状の第１中間タッチパネルフィルム６８が形成される。このフォーミング加工は上記の熱プレス成形の他に真空成形、圧空成形、もしくはこれらの組み合わせにより加工することができる。 Thereafter, the touch panel film piece 64 shown in FIG. 11 is subjected to forming processing to form a first intermediate touch panel film 68 shown in FIG. 12 (touch panel film forming step S7). In the touch panel film forming step S7, the touch panel film piece 64 is preheated to a predetermined temperature range, and the touch panel film piece 64 thus heated is set in a press mold (not shown) and subjected to forming processing by the press mold. That is, a convex forming die and a concave forming die are used as a press die, and a touch panel film piece 64 is interposed between both forming dies, and forming is performed by the convex forming die and the concave forming die, By this processing, the first intermediate touch panel film 68 having the shape shown in FIG. 12 is formed. This forming process can be processed by vacuum forming, pressure forming, or a combination thereof in addition to the above-described heat press forming.
　この第１中間タッチパネルフィルム６８は、上方に延びる立上り部７０（静電容量型タッチパネル１０の周側壁１８に対応する部分）と、この立上り部７０の上端部から内方に平面状に延びる平面状部７２（静電容量型タッチパネル１０の天壁１６に対応する部分）と、立上り部７０の下端部から外方に延びる環状フランジ７４とを有し、導電性パターンＰＴは、立上り部７０、平面状部７２、及び環状フランジ７４に存在するようになり、より具体的に第１及び第２電極パッド１５，１７Ｍは立上がり部７０及び平面状部７０に存在し、第１及び第２接続端子１５Ｔ，１７Ｔは環状フランジ７４に存在する。 The first intermediate touch panel film 68 has a rising portion 70 (portion corresponding to the circumferential side wall 18 of the capacitive touch panel 10) extending upward and a planar shape extending in a planar manner inward from the upper end portion of the rising portion 70. Portion 72 (portion corresponding to the top wall 16 of the capacitive touch panel 10) and an annular flange 74 extending outward from the lower end portion of the rising portion 70, and the conductive pattern PT has a rising portion 70, a flat surface The first and second electrode pads 15 and 17M are present on the rising portion 70 and the flat portion 70, and the first and second connection terminals 15T are formed. , 17T are present on the annular flange 74.

Also in the touch panel film trimming step S8, similarly to the touch panel film removing step S6, for example, using a press die (not shown) or the like, the first intermediate touch panel film 68 is die-cut by this press die, and outward The second intermediate touch panel film 76 shown in FIG. 13 is formed by removing a part (the part where the first and second connection terminals 15T and 17T are formed) leaving the annular flange 74 extending in the middle.
　この第２中間タッチパネルフィルム７６は、静電容量型タッチパネル１０とほぼ同じ形状に形成され、静電容量型タッチパネル１０の周側壁１８に対応する立上り部７０と、その天壁１６に対応する平面状部７２と、その周側壁１８から延びる延長部１９に対応する残留フランジ７８とを有し、このようにして静電容量型タッチパネル１０（タッチパネルフィルム）が形成される。 The second intermediate touch panel film 76 is formed in substantially the same shape as the capacitive touch panel 10, and has a rising portion 70 corresponding to the circumferential side wall 18 of the capacitive touch panel 10 and a planar shape corresponding to the top wall 16 thereof. A portion 72 and a residual flange 78 corresponding to the extension 19 extending from the circumferential side wall 18 are formed, and thus, the capacitive touch panel 10 (touch panel film) is formed.
　その後、成形型を用いて第２中間カバーフィルム６０（外装カバー１４）及び第２中間タッチパネルフィルム７６（静電容量型タッチパネル１０）をインサート成形する（インサート成形工程Ｓ９）。このインサート成形工程Ｓ９においては、図１４及び図１５に示すように、凸状成形金型８０及び凹状成形金型８２を用い、凸状成形金型８０の凸状部８４に第２中間タッチパネルフィルム７６を装着するとともに、凹状成形金型８２の凹状部８６に第２中間カバーフィルム６０を装着し、これらを装着した状態でインサート成形して上述した静電容量型タッチパネルアセンブリ８を成形する。 Thereafter, the second intermediate cover film 60 (the outer cover 14) and the second intermediate touch panel film 76 (the capacitive touch panel 10) are insert-molded using a molding die (insert molding step S9). In the insert molding step S9, as shown in FIG. 14 and FIG. 15, using the convex molding die 80 and the concave molding die 82, a second intermediate touch panel film is formed on the convex portion 84 of the convex molding die 80. The second intermediate cover film 60 is attached to the concave portion 86 of the concave molding die 82 while mounting 76, and in a state in which these are mounted, insert molding is performed to mold the above-described capacitive touch panel assembly 8.
　凸状成形金型８０には、第２中間タッチパネルフィルム７６の内面側形状に対応した凸状部８４が設けられており、第２中間タッチパネルフィルム７６は、かかる凸状部８４に被せるように装着される。尚、この凸状成形金型８０には、第２中間タッチパネルフィルム７６の立上り部７０の下端部及び残留フランジ７８が挿入される溝部が設けられる。 The convex molding die 80 is provided with a convex portion 84 corresponding to the inner surface side shape of the second intermediate touch panel film 76, and the second intermediate touch panel film 76 is mounted so as to cover the convex portion 84. Be done. The convex molding die 80 is provided with a groove portion into which the lower end portion of the rising portion 70 of the second intermediate touch panel film 76 and the residual flange 78 are inserted.
　また、凹状成形金型８２には、第２中間カバーフィルム６０の外面形状に対応した凹状部８６が設けられており、第２中間カバーフィルム６０は、かかる凹状部８６にはめ込むように装着される。 Further, the concave molding die 82 is provided with a concave portion 86 corresponding to the outer surface shape of the second intermediate cover film 60, and the second intermediate cover film 60 is mounted so as to be fitted into the concave portion 86. .
　インサート成形に際し両成形金型８０，８２の型接合面８８，９０を接合した状態においては、図１５に示すように、凸状成形金型８０の凸状部８４（これに装着された第２中間タッチパネルフィルム７６）と凹状成形金型８２の凹状部８６（これに装着された第２中間カバーフィルム６０）との間に、溶融樹脂が流入するキャビティ９２が規定され、このキャビティ９２が静電容量型タッチパネルアセンブリ８の樹脂層１２の形状に対応する。 When the mold joining surfaces 88 and 90 of both molding dies 80 and 82 are joined at the time of insert molding, as shown in FIG. 15, the convex portion 84 of the convex molding die 80 (the second part attached to this) Between the intermediate touch panel film 76) and the concave portion 86 (the second intermediate cover film 60 attached thereto) of the concave molding die 82, a cavity 92 into which the molten resin flows is defined, and this cavity 92 is electrostatic It corresponds to the shape of the resin layer 12 of the capacitive touch panel assembly 8.
　インサート成形工程Ｓ９においては、第２中間タッチパネルフィル７６を装着した凸状成形金型８０と、第２中間カバーフィルム６０を装着した凹状成形金型８２とを型締めして注入口（図示せず）を通してキャビティ９２内に溶融樹脂が注入され、キャビティ９２内に注入された溶融樹脂が冷却固化されて上述した静電容量型タッチパネルアセンブリ８がインサート成形される。ここで、図１５に示す様に、第１及び第２接続端子１５Ｔ，１７Ｔが形成された残留フランジ７８は凸状成形金型８０に設けられた溝部に挿入されているので、この残留フランジ７８（第１及び第２接続端子１５Ｔ，１７Ｔ）へは溶融樹脂が回らず、フレキシブルな状態が維持される。 In the insert molding step S9, the convex molding die 80 to which the second intermediate touch panel film 76 is attached and the concave molding die 82 to which the second intermediate cover film 60 is attached are clamped to form an injection port (not shown). Molten resin is injected into the cavity 92, and the molten resin injected into the cavity 92 is cooled and solidified to insert-mold the capacitive touch panel assembly 8 described above. Here, as shown in FIG. 15, since the residual flange 78 on which the first and second connection terminals 15T and 17T are formed is inserted into the groove portion provided in the convex molding die 80, the residual flange 78 is formed. The molten resin does not go to the (first and second connection terminals 15T and 17T), and the flexible state is maintained.
　このようにして製作した静電容量型タッチパネルアセンブリ８は、図２に示すように、例えばＯＣＡテープ９４などによって、液晶表示手段６の表面側に固定され、このようにして静電容量型タッチパネルアセンブリ８を備えた液晶表示装置２が製作される。 The capacitive touch panel assembly 8 manufactured in this manner is fixed to the surface side of the liquid crystal display means 6 by, for example, an OCA tape 94 as shown in FIG. 2, and thus the capacitive touch panel assembly The liquid crystal display device 2 provided with 8 is manufactured.

For example, in order to give a scratch preventing function to the other surface of the outer cover 14 (cover film) (the surface opposite to the surface on which the print layer 26 is provided), the other surface of the outer cover 14 is used as a functional layer A hard coat layer may be provided, and in order to provide an antireflective function, an antireflective layer may be provided as a functional layer on the other surface of the exterior cover 14 and an antifouling function is provided. For this purpose, an antifouling layer as a functional layer may be provided on the other surface of the exterior cover 14, and a plurality of functional layers may be provided in layers to provide these plural functions.
