Abstract

<P>PROBLEM TO BE SOLVED: To provide a transparent touch panel to prevent a transparent electrode from beeing seen from the outside and a method for manufacturing the same. <P>SOLUTION: At an upper electrode substrate side, a transparent electrode line d1 is arranged as a dummy electrode D1 in spaces S1 and S2 between a common electrode c1 and an X detection electrode x1 and an X detection electrode x2, and at a lower electrode substrate side, a transparent electrode line d2 is arranged as a dummy electrode D2 in a space S3 between adjacent Y detection electrodes yn. Thus, it is possible to reduce the difference of contrast between a section having the common electrode c1, the X detection electrode xb and the Y detection electrode yn and a section where only the dummy electrodes D1 and D2 are arranged. Therefore, an inside transparent electrode is hardly seen when a transparent touch panel is peeked from the outside. <P>COPYRIGHT: (C)2008,JPO&INPIT

透明タッチパネルは、一方の透明シートに形成された複数のX方向電極と、他方の透明シートに形成された複数のY方向電極とが対向配置される構成が一般的である。前記X方向電極およびY方向電極は、例えばITO(Indium TinOxide;酸化インジウムスズ)など、可視光の透過率の高い電極(以下、適宜「透明電極」という)により形成される。  The transparent touch panel generally has a configuration in which a plurality of X-direction electrodes formed on one transparent sheet and a plurality of Y-direction electrodes formed on the other transparent sheet are arranged to face each other. The X direction electrode and the Y direction electrode are formed of an electrode having a high visible light transmittance (hereinafter, referred to as “transparent electrode” as appropriate) such as ITO (Indium Tin Oxide).

しかし、透明電極は、抵抗値が高い場合にはその膜厚が薄く、可視光の透過率が低いために外部から見え難いが、抵抗値が低くなると膜厚が厚くなって可視光の透過率も高くなるため外部から見え易くなるという性質を有する。  However, the transparent electrode has a thin film thickness when the resistance value is high, and it is difficult to see from the outside because the visible light transmittance is low, but when the resistance value is low, the film thickness becomes thick and the visible light transmittance is low. Therefore, it is easy to see from the outside.

したがって、このような性質を有する透明電極が透明シート上に配線されると、特に透明シートのみの部分と、高い抵抗値からなる透明電極が配線された部分との間の境界部分が鮮明となるため、これらの間におけるコントラストの差が大きくなり、外部から透明電極が視認されやすくなるという問題がある。特に、携帯電話機になどにおいては、透明タッチパネルは液晶表示装置の上部(表面側)に配置されるため、液晶表示装置に表示された画面の視認性が低下することになる。  Therefore, when the transparent electrode having such a property is wired on the transparent sheet, a boundary portion between the portion of the transparent sheet alone and the portion where the transparent electrode having a high resistance value is wired becomes clear. Therefore, there is a problem that the difference in contrast between them becomes large and the transparent electrode is easily visible from the outside. In particular, in a mobile phone or the like, since the transparent touch panel is disposed on the upper side (front side) of the liquid crystal display device, the visibility of the screen displayed on the liquid crystal display device is lowered.

本発明は上記従来の課題を解決するためのものであり、外部から内部に配線されている透明電極が見え難くした透明タッチパネル及びその製造方法を提供することを目的としている。  The present invention has been made to solve the above-described conventional problems, and an object thereof is to provide a transparent touch panel in which it is difficult to see a transparent electrode wired from the outside to the inside, and a manufacturing method thereof.

本発明は、少なくとも、Y方向に所定の隙間を有して並ぶ複数の第1の透明電極が配置された第1の基板と、前記Y方向と直交するX方向に所定の隙間を有して並ぶ複数の第2の透明電極が配置された第2の基板と、が対向配置された透明タッチパネルにおいて、
少なくとも一方の基板の前記各電極間の隙間に、第3の透明電極が配置されていることを特徴とするものである。
The present invention has at least a first substrate on which a plurality of first transparent electrodes arranged with a predetermined gap in the Y direction are arranged, and a predetermined gap in the X direction orthogonal to the Y direction. In the transparent touch panel in which the second substrate on which the plurality of second transparent electrodes arranged are arranged to face each other,
A third transparent electrode is disposed in a gap between the electrodes of at least one substrate.

本発明の透明タッチパネルでは、検出用の透明電極間に透明なダミー電極を配置したため、検出用の透明電極が形成された部分と透明なダミー電極が形成された部分と間のコントラスト差を小さくすることができる。よって、外部から検出用の透明電極を見え難くすることができる。  In the transparent touch panel of the present invention, since the transparent dummy electrode is disposed between the transparent electrodes for detection, the contrast difference between the portion where the transparent electrode for detection is formed and the portion where the transparent dummy electrode is formed is reduced. be able to. Therefore, it is possible to make it difficult to see the transparent electrode for detection from the outside.

例えば、前記隙間に共通電極が設けられており、前記第3の透明電極は、前記第1の透明電極と前記共通電極との間、または前記第2の透明電極と前記共通電極との間に設けられているものとして構成される。  For example, a common electrode is provided in the gap, and the third transparent electrode is between the first transparent electrode and the common electrode, or between the second transparent electrode and the common electrode. It is configured as provided.

上記手段では、外部から第1の透明電極および共通電極、あるいは第2の透明電極および共通電極を見え難くすることができる。  In the above means, it is possible to make the first transparent electrode and the common electrode or the second transparent electrode and the common electrode difficult to see from the outside.

上記において、前記第3の透明電極は、その長手方向が前記第1の透明電極または第2の透明電極が延びる方向と同じであるものが好ましい。  In the above, it is preferable that the third transparent electrode has the same longitudinal direction as the direction in which the first transparent electrode or the second transparent electrode extends.

このように、前記第1の透明電極または第2の透明電極と、第3の透明電極(ダミー電極を構成する電極線)とのn長さ方向を揃えておくと、各透明電極と前記ダミー電極との境界部分のコントラスト差をより小さくすることができ、各透明電極をより見え難くすることができる。  In this way, when the n length direction of the first transparent electrode or the second transparent electrode and the third transparent electrode (electrode line constituting the dummy electrode) are aligned, each transparent electrode and the dummy The difference in contrast at the boundary with the electrode can be made smaller, and each transparent electrode can be made more difficult to see.

例えば、前記第3の透明電極が、前記長手方向において所定の寸法で分断されているものとして構成される。  For example, the third transparent electrode is configured to be divided by a predetermined dimension in the longitudinal direction.

上記においては、前記第1の透明電極または前記第2の透明電極には、前記長手方向に所定の間隔で並ぶ凹凸が形成されているものが好ましい。  In the above, it is preferable that the first transparent electrode or the second transparent electrode has irregularities arranged at predetermined intervals in the longitudinal direction.

上記手段では、共通電極とX検出電極とに形成される静電容量、または共通電極とY検出電極とに形成される静電容量を一定とすることができるため、精度の高い検出が可能となる。  In the above means, the capacitance formed on the common electrode and the X detection electrode or the capacitance formed on the common electrode and the Y detection electrode can be made constant, so that highly accurate detection is possible. Become.

さらに、前記第3の透明電極が、他のいずれの電極からも絶縁されているものが好ましい。  Furthermore, it is preferable that the third transparent electrode is insulated from any other electrode.

上記手段では、第3の透明電極としてのダミー電極が形成された部分の静電容量を、第3の透明電極を有しない場合に比較して大きくすることができる。  According to the above means, the capacitance of the portion where the dummy electrode as the third transparent electrode is formed can be increased as compared with the case where the third transparent electrode is not provided.

さらには、前記第1の基板と前記第2の基板は、透明なシートまたは基板で形成され、さらには前記第1の基板と前記第2の基板とが静電容量式の入力手段として機能するものが好ましい。
上記手段では静電容量式の透明タッチパネルとすることができる。
Furthermore, the first substrate and the second substrate are formed of a transparent sheet or substrate, and further, the first substrate and the second substrate function as a capacitance type input means. Those are preferred.
The above means can be a capacitive transparent touch panel.

本発明では、位置決めマークを基準として各電極を配置することができる。このため、X検出電極とY検出電極との間における位置ずれ量を小さくすることができ、結果として精度の高い透明タッチパネルとすることができる。  In the present invention, each electrode can be arranged based on the positioning mark. For this reason, the amount of positional deviation between the X detection electrode and the Y detection electrode can be reduced, and as a result, a highly accurate transparent touch panel can be obtained.

前記(b)工程では、前記X検出電極、共通電極およびダミー電極が一度に焼き付けられ、または前記Y検出電極とダミー電極とが一度に焼き付けられるものが好ましい。  In the step (b), it is preferable that the X detection electrode, the common electrode, and the dummy electrode are baked at a time, or the Y detection electrode and the dummy electrode are baked at a time.

上記手段では、一度の工程で、上部電極基板ではX検出電極、共通電極およびダミー電極を焼き付けることができ、下部電極基板ではY検出電極およびダミー電極を焼き付けることができる。よって、製造工程の一部を省略ないしは簡略化することが可能となる。  In the above means, the X detection electrode, the common electrode and the dummy electrode can be baked on the upper electrode substrate, and the Y detection electrode and the dummy electrode can be baked on the lower electrode substrate in one step. Therefore, part of the manufacturing process can be omitted or simplified.

本発明の透明タッチパネルでは、透明シート上のX検出電極またはY検出電極が形成された部分の光透過率と、ダミー電極が形成された部分の光透過率との差を小さし、全面において均一な透明度とすることができる。このため、外部から透明タッチパネルを覗いたときに、外部から透明電極を視認し難くすることができる。  In the transparent touch panel of the present invention, the difference between the light transmittance of the portion where the X detection electrode or the Y detection electrode is formed on the transparent sheet and the light transmittance of the portion where the dummy electrode is formed is small, and uniform over the entire surface. Transparency. For this reason, when a transparent touch panel is looked at from the outside, it can be made difficult to visually recognize a transparent electrode from the outside.

また本発明の製造方法では、X検出電極とY検出電極との間における位置ずれ量を小さくするとができるため、精度の高い透明タッチパネルを形成することが可能となる。  Moreover, in the manufacturing method of this invention, since the positional offset amount between X detection electrode and Y detection electrode can be made small, it becomes possible to form a highly accurate transparent touch panel.

以下、本発明の実施の形態について適宜図面を参照しつつ説明する。

Embodiments of the present invention will be described below with reference to the drawings as appropriate.

FIG. 5 is an enlarged plan view showing the dummy electrode provided with the upper electrode substrate, and FIG. 6 is an enlarged plan view showing the dummy electrode provided with the lower electrode substrate. In FIG. 4, theupper electrode substrate 10 side is indicated by a solid line, and thelower electrode substrate 20 side is indicated by a dotted line.

本発明の透明タッチパネル1は、例えば携帯電話機、PDA(Personal Digital Assistants)などのモバイル機器をはじめとするさまざまな電子機器に搭載される。  Thetransparent touch panel 1 of the present invention is mounted on various electronic devices such as mobile devices such as mobile phones and PDAs (Personal Digital Assistants).

図1に示すように、本発明の透明タッチパネル1は上部電極基板10と下部電極基板20を有している。これら上部電極基板10と下部電極基板20とは板厚方向に積層された状態で貼り合わせられ、一枚の透明タッチパネル1が構成されている。  As shown in FIG. 1, thetransparent touch panel 1 of the present invention has anupper electrode substrate 10 and alower electrode substrate 20. Theupper electrode substrate 10 and thelower electrode substrate 20 are bonded together in a state of being laminated in the plate thickness direction, and onetransparent touch panel 1 is configured.

図2に示すように、上部電極基板10は、PETやアクリルなどからなる絶縁性および可撓性を有する薄手の透明シート(第1の基板)11で形成されている。前記透明シート11の表面には、Y方向に延びる複数のX検出電極(第1の透明電極)xn(個別にx1,x2,x3,・・・,x13で示す)と複数の共通電極cn(個別にc1,c2,c3,・・・,c13で示す)がX方向に交互に配置されている。X検出電極xnと共通電極cnとは、ITO(IndiumTin Oxide;酸化インジウムスズ)など可視光の透過率の高い電極(透明電極)により形成されている。  As shown in FIG. 2, theupper electrode substrate 10 is formed of a thin transparent sheet (first substrate) 11 having insulating properties and flexibility made of PET, acrylic, or the like. On the surface of thetransparent sheet 11, a plurality of X detection electrodes (first transparent electrodes) xn (indicated by x1, x2, x3,..., X13 individually) extending in the Y direction and a plurality of common electrodes cn ( (Indicated by c1, c2, c3,..., C13) are alternately arranged in the X direction. The X detection electrode xn and the common electrode cn are formed of an electrode (transparent electrode) having a high visible light transmittance such as ITO (Indium Tin Oxide).

前記X検出電極x1,x2,x3,・・・,x13の前記共通電極cnと対向するX方向の左右両辺には、複数の凹部と凸部とからなる凹凸がY方向に沿って交互に所定の間隔で配置されている。すなわち、隣り合うX検出電極xnと共通電極cnとは所定の距離を隔てX方向の左右にて対向しており、これらの間には小さなスペース(隙間)S1,S2が形成されている。共通電極cnと前記X検出電極xnの凸部との間に形成されるスペース(第1の隙間)S1は狭く、共通電極cnと前記X検出電極xnの凹部との間に形成されるスペース(第2の隙間)S2はそれよりも広い。そして、狭いスペースS1と広いスペースS2とは、各X検出電極xnのX方向の両側位置にY方向に沿って交互に配置されている。  On the left and right sides of the X detection electrodes x1, x2, x3,..., X13 facing the common electrode cn, irregularities including a plurality of concave portions and convex portions are alternately specified along the Y direction. Are arranged at intervals. That is, the adjacent X detection electrode xn and the common electrode cn are opposed to each other in the X direction at a predetermined distance, and small spaces (gap) S1 and S2 are formed between them. A space (first gap) S1 formed between the common electrode cn and the convex portion of the X detection electrode xn is narrow, and a space formed between the common electrode cn and the concave portion of the X detection electrode xn ( The second gap S2 is wider than that. The narrow space S1 and the wide space S2 are alternately arranged along the Y direction at both side positions in the X direction of the X detection electrodes xn.

前記X検出電極xnと前記共通電極cnとの間に所定の電圧が印加されると、各電極間に静電容量が形成される。前記のように前記X検出電極x1,x2,x3,・・・,x13の左右両辺に複数の凹凸を形成しておくと、例えば共通電極c1については、前記共通電極c1とX検出電極x1との間に形成される静電容量と、前記共通電極c1とX検出電極x2との間に形成される静電容量との差(ばらつき)を小さく抑えることができる。このことは、他の共通電極cnと、これにX方向の左右両側の位置にて隣接する他のX検出電極xnとの間でも同様である。すなわち、複数の凹凸は、ある共通電極cnとこれに隣接するX検出電極xnとの間に形成される静電容量を、いずれの組み合わせにおいてもほぼ一定とすることができ、精度の高い検出を可能とする。なお、凹凸は前記X検出電極xnの左右両辺に形成されるものに限られるものではなく、前記共通電極cnの左右両辺に形成される構成であってもよいし、あるいは前記X検出電極xnと前記共通電極cnの双方に形成される構成であってもよい。  When a predetermined voltage is applied between the X detection electrode xn and the common electrode cn, a capacitance is formed between the electrodes. If a plurality of irregularities are formed on the left and right sides of the X detection electrodes x1, x2, x3,..., X13 as described above, for example, for the common electrode c1, the common electrode c1 and the X detection electrode x1 The difference (variation) between the capacitance formed between the capacitance and the capacitance formed between the common electrode c1 and the X detection electrode x2 can be reduced. This is the same between the other common electrode cn and the other X detection electrode xn adjacent to the common electrode cn at positions on the left and right sides in the X direction. That is, the plurality of irregularities can make the capacitance formed between a certain common electrode cn and the X detection electrode xn adjacent to the common electrode cn almost constant in any combination, and can detect with high accuracy. Make it possible. The irregularities are not limited to those formed on the left and right sides of the X detection electrode xn, but may be formed on both the left and right sides of the common electrode cn, or the X detection electrode xn The structure formed in both the said common electrodes cn may be sufficient.

図5に拡大して示すように、上部電極基板10側の透明シート11の前記スペースS1,S2内にはダミー電極(第3の透明電極)D1を設けられている。前記ダミー電極D1は、前記X検出電極x2または共通電極c1,c2が延びる長手方向(Y方向)を長辺とする複数の細く透明な電極線d1で形成されており、このような微細な電極線d1が並び方向(X方向)に沿って一定の間隔で配置されている。個々の電極線d1は、図5に示すように小片状に分断された状態で配置されていてもよいし、また前記X検出電極xnに形成された個々の凹部や凸部の長さ寸法と同程度の長さ寸法で形成されていてもよい。あるいはX検出電極xn自体の長さ寸法と同程度の長さ寸法を有する状態で配置されていてもよい。ただし、個々の電極線d1は、前記X検出電極xnおよび前記共通電極cnをはじめとする他のいずれの電極線d1にも接触することなく、電気的に絶縁された状態で配置されていることが好ましい。  As shown in an enlarged view in FIG. 5, dummy electrodes (third transparent electrodes) D <b> 1 are provided in the spaces S <b> 1 and S <b> 2 of thetransparent sheet 11 on theupper electrode substrate 10 side. The dummy electrode D1 is formed of a plurality of thin and transparent electrode lines d1 having a long side in the longitudinal direction (Y direction) in which the X detection electrode x2 or the common electrodes c1 and c2 extend. The lines d1 are arranged at regular intervals along the arrangement direction (X direction). The individual electrode lines d1 may be arranged in a state of being divided into small pieces as shown in FIG. 5, and the length dimensions of the individual recesses and projections formed in the X detection electrode xn. It may be formed with the same length. Or you may arrange | position in the state which has a length dimension comparable as the length dimension of X detection electrode xn itself. However, each electrode line d1 is disposed in an electrically insulated state without contacting any other electrode line d1 including the X detection electrode xn and the common electrode cn. Is preferred.

このように電極線d1を他のいずれの電極からも絶縁させた状態にしておくと、例えばX検出電極xnと共通電極cnとの間に複数のコンデンサを直列に配置した場合と等価にできる。あるいは複数の電極線d1が有する幅寸法分だけ、X検出電極xnと共通電極cnとの対向距離が狭まった場合と等価となるため、この間の静電容量を大きくすることができる。  If the electrode line d1 is insulated from any other electrode in this way, it can be equivalent to, for example, a case where a plurality of capacitors are arranged in series between the X detection electrode xn and the common electrode cn. Alternatively, this is equivalent to the case where the opposing distance between the X detection electrode xn and the common electrode cn is reduced by the width dimension of the plurality of electrode lines d1, and thus the capacitance between them can be increased.

図1および図2に示すように、前記透明シート11のY2方向の縁部には、前記透明シート11から連続して延びる可撓性配線部10Aが形成されている。この可撓性配線部10Aには、前記X検出電極x1,x2,x3,・・・,x13から延びる引き出し線13が配線されている。各引き出し線13は、例えば銀など導電性の金属でパターン形成したものであり、互いに接することなく可撓性配線部10Aを介して外部に引き出されている。  As shown in FIGS. 1 and 2, aflexible wiring portion 10 </ b> A that extends continuously from thetransparent sheet 11 is formed at the edge of thetransparent sheet 11 in the Y2 direction. Leadwires 13 extending from the X detection electrodes x1, x2, x3,..., X13 are wired to theflexible wiring portion 10A. Eachlead wire 13 is formed by patterning with a conductive metal such as silver, for example, and is led to the outside via theflexible wiring portion 10A without being in contact with each other.

またすべての共通電極c1,c2,c3,・・・,c13は、図示Y1側の位置にて図示X方向に沿うように形成された接続電極14を介して導通接続されている。前記接続電極14は、例えば銀などの導電性の金属によりパターン形成されている。そして、X方向の中央に位置する共通電極c7のY2側の端部には、同じく銀などの導電性の金属で形成した引き出し線15が接続されており、引き出し線15は可撓性配線部10Aを介して外部に引き出されている。  Further, all the common electrodes c1, c2, c3,..., C13 are conductively connected through aconnection electrode 14 formed along the X direction in the drawing at a position on the Y1 side in the drawing. Theconnection electrode 14 is patterned with a conductive metal such as silver. Thelead wire 15 formed of a conductive metal such as silver is connected to the Y2 side end of the common electrode c7 located at the center in the X direction. Thelead wire 15 is a flexible wiring portion. It is pulled out through 10A.

図3に示すように、下部電極基板20は、ガラス基板またはアクリルなど絶縁性を有する透明基板(第2の基板)21で形成されている。前記透明基板21の表面には、前記X検出電極Xnおよび共通電極cnと直交する図示X方向に延びる複数の複数のY検出電極(第2の透明電極))yn(個別にy1,y2,・・・,y16で示す)が配線されている。なお、Y検出電極ynもITO(IndiumTin Oxide;酸化インジウムスズ)などからなる透明電極で形成されている。  As shown in FIG. 3, thelower electrode substrate 20 is formed of an insulating transparent substrate (second substrate) 21 such as a glass substrate or acrylic. On the surface of thetransparent substrate 21, a plurality of Y detection electrodes (second transparent electrodes)) yn (individually y1, y2,... Extending in the X direction shown in the figure orthogonal to the X detection electrode Xn and the common electrode cn). .., indicated by y16). The Y detection electrode yn is also formed of a transparent electrode made of ITO (Indium Tin Oxide).

各Y検出電極y1,y2,・・・,y16は互い平行であり、同一平面内の隣り合うY検出電極yn間にはほぼ一定の領域からなるスペース(第3の隙間)S3がそれぞれ設けられている。  Each of the Y detection electrodes y1, y2,..., Y16 is parallel to each other, and a space (third gap) S3 including a substantially constant area is provided between adjacent Y detection electrodes yn in the same plane. ing.

前記下部電極基板20に縁部には複数の引き出し線23A,23Bが設けられている。各引き出し線23Aは、Y検出電極y1ないしY検出電極y8の図示X1側の端部に個別に接続されており、下部電極基板20の図示X1側およびY2側の縁部に沿って引き回されている。同様に、各引き出し線23Bは、Y検出電極y9ないしY検出電極y16の図示X2側の端部に個別に接続されており、下部電極基板20の図示X2側およびY2側の縁部に沿って引き回されている。  Thelower electrode substrate 20 is provided with a plurality oflead lines 23A and 23B at the edge. Eachlead line 23A is individually connected to the end portion on the X1 side of the Y detection electrode y1 to the Y detection electrode y8, and is led along the X1 side and Y2 side edges of thelower electrode substrate 20. ing. Similarly, each lead-outline 23B is individually connected to the end of the Y detection electrode y9 to the Y detection electrode y16 on the X2 side in the drawing, and along the X2 side and the Y2 side edge of thelower electrode substrate 20 along the edge. Has been routed.

下部電極基板20のY2側の縁部には、透明基板21の端部から連続して凸状に延びる延出部20Aが一体に形成されている。前記引き出し線23A,23Bは例えば銀など導電性の金属でパターン形成されており、互いに接することなく前記下部電極基板20のY2側の縁部および前記延出部20Aを介して外部に引き出されている。  Anextended portion 20 </ b> A that extends continuously from the end portion of thetransparent substrate 21 in a convex shape is integrally formed at the edge portion of thelower electrode substrate 20 on the Y <b> 2 side. The lead lines 23A and 23B are patterned with a conductive metal such as silver, for example, and are led out to the outside through the Y2 side edge of thelower electrode substrate 20 and theextension part 20A without contacting each other. Yes.

図6に示すように、前記スペースS3内にはダミー電極(第3の透明電極)D2が配置されている。ダミー電極D2は、前記Y検出電極ynに対して平行となるX方向を長手方向とする細い透明な電極線d2で形成されており、このような電極線d2が前記スペースS3内に並び方向(Y方向)に一定の間隔で配置されている。前記細い電極線d2は前記Y検出電極ynと同じ長さでもよいし、または上記のようにそれよりも短い寸法からなる複数の電極線d2が長手方向に並ぶように配置されるものであってもよい。ただし、個々の電極線d2は、前記Y検出電極ynや他のいずれの電極線d2とも接触することなく、電気的に絶縁された状態で配置されている。このように電極線d2を他のいずれの電極からも絶縁させた状態にしておくと、上記同様に静電容量を大きくすることができる。  As shown in FIG. 6, a dummy electrode (third transparent electrode) D2 is disposed in the space S3. The dummy electrode D2 is formed of a thin transparent electrode line d2 whose longitudinal direction is the X direction parallel to the Y detection electrode yn. Such an electrode line d2 is aligned in the space S3 ( (Y direction) are arranged at regular intervals. The thin electrode line d2 may have the same length as the Y detection electrode yn, or a plurality of electrode lines d2 having a shorter dimension as described above are arranged in the longitudinal direction. Also good. However, the individual electrode lines d2 are arranged in an electrically insulated state without contacting the Y detection electrode yn or any other electrode line d2. When the electrode line d2 is insulated from any other electrode as described above, the capacitance can be increased as described above.

上部電極基板10は下部電極基板20の上に重ねた状態で積層される。図4に示すように、上部電極基板10側の第2のスペースS2の下に下部電極基板20側に設けられた前記Y検出電極ynが配置される。そして、上部電極基板10側の前記第1,第2のスペースS1,S2内にはダミー電極D1として電極線d1が配置され、下部電極基板20側の第3のスペースS3にはダミー電極D2として電極線d2が配線される。  Theupper electrode substrate 10 is stacked on thelower electrode substrate 20 so as to be stacked. As shown in FIG. 4, the Y detection electrode yn provided on thelower electrode substrate 20 side is disposed below the second space S2 on theupper electrode substrate 10 side. An electrode line d1 is disposed as a dummy electrode D1 in the first and second spaces S1 and S2 on theupper electrode substrate 10 side, and a dummy electrode D2 is disposed on the third space S3 on thelower electrode substrate 20 side. The electrode line d2 is wired.

このように、本願発明では、上部電極基板10においては第1,第2のスペースS1,S2内に多数のダミー電極D1を配置することができ、下部電極基板20においては第3のスペースS3に多数のダミー電極D2を配置することができる。このため、上部電極基板10においてはX検出電極xnや共通電極cnが形成された部分とダミー電極D1のみが形成された第1,第2のスペースS1,S2部分との間におけるコントラストの差を小さくできる。同様に、下部電極基板20においてはY検出電極ynが形成された部分とダミー電極D2のみが形成された第3のスペースS3部分との間におけるコントラストの差を小さくすることができる。よって、外部上方から透明タッチパネル1の表面を覗いたときに、内部に配線されているX検出電極xn、共通電極cnおよびY検出電極ynを見え難くすることができる。このため、このような透明タッチパネル1を携帯電話機などの液晶表示装置の上部に搭載したときであっても、前記液晶表示装置に表示された画面の視認性が低下することを避けることができる。  Thus, in the present invention, a large number of dummy electrodes D1 can be arranged in the first and second spaces S1, S2 in theupper electrode substrate 10, and in the third space S3 in thelower electrode substrate 20. A large number of dummy electrodes D2 can be arranged. Therefore, in theupper electrode substrate 10, the difference in contrast between the portion where the X detection electrode xn and the common electrode cn are formed and the first and second spaces S1 and S2 where only the dummy electrode D1 is formed. Can be small. Similarly, in thelower electrode substrate 20, the difference in contrast between the portion where the Y detection electrode yn is formed and the third space S3 portion where only the dummy electrode D2 is formed can be reduced. Therefore, when the surface of thetransparent touch panel 1 is looked at from the outside, it is possible to make the X detection electrode xn, the common electrode cn, and the Y detection electrode yn wired inside difficult to see. For this reason, even when such atransparent touch panel 1 is mounted on the upper part of a liquid crystal display device such as a mobile phone, it is possible to avoid a decrease in the visibility of the screen displayed on the liquid crystal display device.

透明タッチパネル1では、前記共通電極cnを基準に、まず前記X検出電極x1ないしxnに対し所定のタイミングで電圧が順次印加され、続いて前記Y検出電極y1ないしynに対しに所定のタイミングで電圧が順次印加される。これにより、共通電極cnと各前記X検出電極x1ないしxn間、および共通電極cnと各前記X検出電極y1ないしyn間に所定の静電容量がそれぞれ所定のタイミングで順次形成される。操作者の指などが、図示しない表面パネルなどを介して透明タッチパネルの表面に接触すると、指の位置に近い部分の静電容量が変化する。このため、各静電容量の変化状態を電圧変化として検出することにより、前記指の座標位置を検出することができる。すなわち、この前記透明シート(第1の基板)11と前記透明基板(第2の基板)21とを有する透明タッチパネルは、静電容量式の座標入力手段として機能を有する。  In thetransparent touch panel 1, with reference to the common electrode cn, first, a voltage is sequentially applied to the X detection electrodes x1 to xn at a predetermined timing, and then a voltage is applied to the Y detection electrodes y1 to yn at a predetermined timing. Are sequentially applied. Accordingly, a predetermined capacitance is sequentially formed at a predetermined timing between the common electrode cn and each of the X detection electrodes x1 to xn, and between the common electrode cn and each of the X detection electrodes y1 to yn. When an operator's finger or the like comes into contact with the surface of the transparent touch panel via a surface panel (not shown) or the like, the capacitance of the portion close to the position of the finger changes. For this reason, the coordinate position of the finger can be detected by detecting the change state of each capacitance as a voltage change. That is, the transparent touch panel having the transparent sheet (first substrate) 11 and the transparent substrate (second substrate) 21 functions as a capacitive coordinate input unit.

上記実施の形態では、前記共通電極cnがX検出電極x1ないしxn間に配置される構成を示したが、前記共通電極cnはY検出電極y1ないしyn間に配置される構成であってもよい。なお、前記共通電極cnは必須のものではないので、上部電極基板10が下部電極基板20と同様の構成、すなわちX検出電極x1ないしxnのみを有する構成であってもよい。  In the above embodiment, the common electrode cn is arranged between the X detection electrodes x1 to xn. However, the common electrode cn may be arranged between the Y detection electrodes y1 to yn. . Since the common electrode cn is not essential, theupper electrode substrate 10 may have a configuration similar to that of thelower electrode substrate 20, that is, a configuration having only the X detection electrodes x1 to xn.

次に、上記透明タッチパネルの製造方法について説明する。
図7Aないし図7Hは本発明における透明タッチパネルの製造方法を示す工程図である。
Next, the manufacturing method of the said transparent touch panel is demonstrated.
7A to 7H are process diagrams showing a method for manufacturing a transparent touch panel according to the present invention.

以下においては、1枚の透明基板41上に複数の上部電極基板10または下部電極基板20を形成し、一度に複数の透明タッチパネルを製造する方法について説明する。なお、以下の第1工程から第8の工程までは上部電極基板10と下部電極基板20との間で共通である。  Hereinafter, a method of forming a plurality of transparent touch panels at a time by forming a plurality ofupper electrode substrates 10 orlower electrode substrates 20 on onetransparent substrate 41 will be described. The following first to eighth steps are common between theupper electrode substrate 10 and thelower electrode substrate 20.

図7Aに示すように、第1の工程では、透明基板41の上に透明抵抗層42を形成する。前記透明基板41は、上記の透明シート11および透明基板21に相当する。透明抵抗層42は、ITO(Indium TinOxide;酸化インジウムスズ)であり、例えばスパッタ法や真空蒸着法などを用いて成膜され、後述するように透明電極を形成する。  As shown in FIG. 7A, in the first step, thetransparent resistance layer 42 is formed on thetransparent substrate 41. Thetransparent substrate 41 corresponds to thetransparent sheet 11 and thetransparent substrate 21 described above. Thetransparent resistance layer 42 is made of ITO (Indium Tin Oxide) and is formed by using, for example, a sputtering method or a vacuum deposition method, and forms a transparent electrode as described later.

図7Bに示すように、第2の工程では、透明抵抗層42の表面にレジスト層43が印刷等の手段により形成される。このとき使用されるレジスト層43は、例えば緑色のような有色のレジスト材が使用される。  As shown in FIG. 7B, in the second step, a resistlayer 43 is formed on the surface of thetransparent resistance layer 42 by means such as printing. The resistlayer 43 used at this time is a colored resist material such as green.

図7Cに示すように、第3の工程では、前記レジスト層43に配線パターンが形成されたマスク50を対向配置した状態で露光することにより、前記所定の配線パターンが前記レジスト層43に焼き付けられる。なお、上部電極基板10用のマスク50にはX検出電極xn、共通電極cnおよびダミー電極D1を形成するための孔が形成されており、下部電極基板20用のマスク50にはY検出電極ynおよびダミー電極D2を形成するための孔が形成されている。  As shown in FIG. 7C, in the third step, the predetermined wiring pattern is baked on the resistlayer 43 by exposing the resistlayer 43 with amask 50 on which the wiring pattern is formed facing each other. . Note that holes for forming the X detection electrode xn, the common electrode cn, and the dummy electrode D1 are formed in themask 50 for theupper electrode substrate 10, and the Y detection electrode yn is formed in themask 50 for thelower electrode substrate 20. And the hole for forming dummy electrode D2 is formed.

図7Dに示すように、第4の工程では、前記レジスト層43上の所定の位置に位置決め用の第2のレジストからなるマーク44が部分的に印刷される。前記マーク44を形成する第2のレジストは、前記レジスト層43と見分けが付く程度に異なる色であることが好ましい。あるいは、マーク44の下層側に位置するレジスト層43の色が透けて見えるように、第2のレジストを透明な色のレジスト材で形成した構成であってもよい。  As shown in FIG. 7D, in the fourth step, amark 44 made of a positioning second resist is partially printed at a predetermined position on the resistlayer 43. The second resist forming themark 44 preferably has a color different from that of the resistlayer 43. Or the structure which formed the 2nd resist with the resist material of the transparent color so that the color of the resistlayer 43 located in the lower layer side of themark 44 can be seen through may be sufficient.

前記マーク44が印刷される位置は、例えば前記X検出電極xn、共通電極cnおよびダミー電極D1が形成される領域の外側の縁(欄外の位置)が好ましい。前記マーク44を形成する第2のレジストは、透明タッチパネル1の組立て時における位置決め用のマーク44であり、組立て完成後は不要となる。このため、前記のようにマーク44を前記欄外の位置に形成しておくと、透明タッチパネル1の組立て完成後に容易に切除することが可能となる。  The position where themark 44 is printed is preferably, for example, the outer edge (outside position) of the region where the X detection electrode xn, the common electrode cn, and the dummy electrode D1 are formed. The second resist forming themark 44 is apositioning mark 44 when thetransparent touch panel 1 is assembled, and is not required after the assembly is completed. For this reason, if themark 44 is formed at a position outside the margin as described above, it can be easily removed after the assembly of thetransparent touch panel 1 is completed.

なお、前記第2のレジストを、前記レジスト層43上の少なくとも2箇所以上の位置に形成する構成とすれば、第8の工程以下に説明する位置決めのためのマーク44として用いることが可能である。  If the second resist is formed at at least two positions on the resistlayer 43, it can be used as apositioning mark 44 described below in the eighth step. .

前記第3の工程と第4の工程の順番は逆の関係であってもよい。すなわち。前記レジスト層43上の所定の位置に位置決め用の第2のレジスト(マーク44)が部分的に印刷され、その後にマスクを用いての露光を行うものであってもよい。この場合、マスク50の位置決めが、前記マーク44を基準に高精度に行うことが可能となる。  The order of the third step and the fourth step may be reversed. That is. The positioning second resist (mark 44) may be partially printed at a predetermined position on the resistlayer 43, and then exposed using a mask. In this case, themask 50 can be positioned with high accuracy based on themark 44.

図7Eに示すように、第5の工程では前記レジスト層43の現像を行う。このとき、透明基板41の上には必要なレジスト層43だけが残り、不要なレジスト層43が除去される。また第2のレジストからなるマーク44は除去されず、その下に位置するレジスト層43とともに残される。  As shown in FIG. 7E, in the fifth step, the resistlayer 43 is developed. At this time, only the necessary resistlayer 43 remains on thetransparent substrate 41, and the unnecessary resistlayer 43 is removed. Further, themark 44 made of the second resist is not removed but remains with the resistlayer 43 located therebelow.

図7Fに示すように、第6の工程では、透明抵抗層42に対しエッチング処理を行うことにより、前記透明基板41の上に所定の形状からなる透明電極が形成される。すなわち、上部電極基板10であればX検出電極xn、共通電極cnおよびダミー電極D1が形成され、下部電極基板20であればY検出電極ynおよびダミー電極D2が形成される。なお、このときには、前記透明基板41上に第2のレジスト(マーク44)が残されている。  As shown in FIG. 7F, in the sixth step, a transparent electrode having a predetermined shape is formed on thetransparent substrate 41 by performing an etching process on thetransparent resistance layer 42. That is, the X detection electrode xn, the common electrode cn, and the dummy electrode D1 are formed in theupper electrode substrate 10, and the Y detection electrode yn and the dummy electrode D2 are formed in thelower electrode substrate 20. At this time, the second resist (mark 44) is left on thetransparent substrate 41.

図7Gに示すように、第7の工程では、マーク44を形成する第2のレジストの部分を除くすべてのレジスト層43が前記透明基板41上から除去される。  As shown in FIG. 7G, in the seventh step, all of the resistlayer 43 except the second resist portion that forms themark 44 is removed from thetransparent substrate 41.

上部電極基板10および下部電極基板20は、上記第1の工程ないし第7の工程が行われることによりそれぞれ形成される。  Theupper electrode substrate 10 and thelower electrode substrate 20 are respectively formed by performing the first to seventh steps.

第8の工程では、上記第1の工程ないし第7の工程を経て形成された上部電極基板10と下部電極基板20の表面が、カメラを有する画像認識装置(図示せず)を用いて撮影され、その画像データがそれぞれ別々に読み込まれる。前記画像認識装置では、上部電極基板10および下部電極基板20の表面の2箇所以上の箇所に設けられているマーク44の位置をパターン認識し、前記マーク44を基準とする座標データを作成する。そして、前記マーク44を基準とした上で、前記透明基板41の表面に各種の導線が銀などの導電性材料を用いて印刷される。すなわち、上部電極基板10の場合には、透明シート11の縁部に前記マーク44を基準として引き出し線13,15および接続電極14が印刷される。同様に、上部電極基板10の場合には、透明基板21の縁部に前記マーク44を基準として引き出し線23A,23Bが印刷される。このため、上部電極基板10に形成された引き出し線13,15および接続電極14、下部電極基板20に形成された引き出し線23A,23Bなどを高精度に配線することができる。よって、下部電極基板20の上に上部電極基板10を積層したときに、上部電極基板10側のX検出電極xnと下部電極基板20側のY検出電極ynとの間での、水平面に平行な方向における位置ずれ量を小さくするとができるため、精度の高い透明タッチパネルを形成することができる。  In the eighth step, the surfaces of theupper electrode substrate 10 and thelower electrode substrate 20 formed through the first to seventh steps are photographed using an image recognition device (not shown) having a camera. The image data is read separately. In the image recognition apparatus, the positions of themarks 44 provided at two or more places on the surface of theupper electrode substrate 10 and thelower electrode substrate 20 are pattern-recognized, and coordinate data based on themarks 44 is created. Then, on the basis of themark 44, various conductive wires are printed on the surface of thetransparent substrate 41 using a conductive material such as silver. That is, in the case of theupper electrode substrate 10, the lead lines 13 and 15 and theconnection electrode 14 are printed on the edge of thetransparent sheet 11 with themark 44 as a reference. Similarly, in the case of theupper electrode substrate 10, lead lines 23 </ b> A and 23 </ b> B are printed on the edge of thetransparent substrate 21 with themark 44 as a reference. Therefore, the lead lines 13 and 15 and theconnection electrode 14 formed on theupper electrode substrate 10 and thelead lines 23A and 23B formed on thelower electrode substrate 20 can be wired with high accuracy. Therefore, when theupper electrode substrate 10 is stacked on thelower electrode substrate 20, the X detection electrode xn on theupper electrode substrate 10 side and the Y detection electrode yn on thelower electrode substrate 20 side are parallel to the horizontal plane. Since the amount of positional deviation in the direction can be reduced, a highly accurate transparent touch panel can be formed.

図7Hに示すように、第9の工程では、前記マーク44を基準として、下部電極基板20と、その上に積層された上部電極基板10とが張り合わされる。これにより、複数の透明タッチパネル1を有するシート状の透明タッチパネルが一体的に製造される。この一体化されたシート状の透明タッチパネル1では、各下部電極基板20の上に各上部電極基板10が高精度に位置決めされている。  As shown in FIG. 7H, in the ninth step, thelower electrode substrate 20 and theupper electrode substrate 10 laminated thereon are bonded together with themark 44 as a reference. Thereby, the sheet-like transparent touch panel which has the sometransparent touch panel 1 is manufactured integrally. In the integrated sheet-liketransparent touch panel 1, eachupper electrode substrate 10 is positioned with high accuracy on eachlower electrode substrate 20.

続く第10の工程では、前記シート状の透明タッチパネルが、個々の透明タッチパネルに切り分けられ分離される。この際、前記欄外の位置に設けられたマーク44を形成する第2のレジストおよびその下部のレジスト層43が、前記透明タッチパネルから同時に切除される。これにより、透明タッチパネル1が完成する。  In the subsequent tenth step, the sheet-like transparent touch panel is cut and separated into individual transparent touch panels. At this time, the second resist forming themark 44 provided at the outside position and the resistlayer 43 under the mark are simultaneously cut off from the transparent touch panel. Thereby, thetransparent touch panel 1 is completed.

上記実施の形態では、第9ないし第10の工程において、シート状の透明タッチパネルを一体的に形成した後に、切り分けて個々の透明タッチパネルを完成させる工程をしたが本発明はこれに限られるものはない。すなわち、第8の工程の次に、前記透明基板21に形成された下部電極基板20とを個々の下部電極基板20に切り分け、さらに前記透明シート11に形成された上部電極基板10とを個々の上部電極基板10に切り分け、その後に前記分離後の下部電極基板20の上に前記分離後の上部電極基板10を重ねることにより、透明タッチパネルを完成させる構成であってもよい。  In the above embodiment, after the sheet-like transparent touch panel is integrally formed in the ninth to tenth steps, the process of cutting and completing each transparent touch panel is performed, but the present invention is not limited to this. Absent. That is, after the eighth step, thelower electrode substrate 20 formed on thetransparent substrate 21 is cut into individuallower electrode substrates 20, and theupper electrode substrate 10 formed on thetransparent sheet 11 is further divided into individual electrodes. The transparent touch panel may be completed by cutting theupper electrode substrate 10 and then overlapping the separatedupper electrode substrate 10 on the separatedlower electrode substrate 20.
