本發明，係有關於將檢測出觸碰位置之感測器電極藉由細線之網格來構成的觸控面板。The present invention relates to a touch panel configured by a grid of thin lines for sensor electrodes that detect a touch position.

圖1以及圖2A、2B，係為作為此種觸控面板之先前技術例，而對於在日本專利申請公開2017-103317號公報(2017年6月8日發行)中所記載之靜電電容式之觸控面板的構成作展示者。此觸控面板，係被設為在透明基板10上，依序層積形成第1導體層、絕緣層、第2導體層以及保護膜之構成。在圖1中，以矩形框所包圍的部份，係為感測器電極所位置之感測器區域20，在圖1中，係將感測器電極之詳細圖示作省略。FIGS. 1 and 2A and 2B are examples of the prior art of such a touch panel, and for the electrostatic capacitance type described in Japanese Patent Application Publication No. 2017-103317 (issued on June 8, 2017) The composition of the touch panel serves as a presenter. This touch panel is configured such that a first conductor layer, an insulating layer, a second conductor layer, and a protective film are sequentially stacked on the transparent substrate 10. In FIG. 1, the part surrounded by the rectangular frame is the sensor region 20 where the sensor electrode is located. In FIG. 1, the detailed illustration of the sensor electrode is omitted.

感測器電極，係由第1感測器電極和第2感測器電極所成，第1感測器電極係藉由第1導體層而被形成，第2感測器電極係藉由第2導體層而被形成。The sensor electrode is formed by the first sensor electrode and the second sensor electrode, the first sensor electrode is formed by the first conductor layer, and the second sensor electrode is formed by the 2 conductor layers.

第1感測器電極30，係如同圖2A中所示一般，將使被配列在與感測器區域20之長邊21相平行的X方向上之複數之島狀電極31藉由連結部32而被作連結所成的電極列33，在與感測器區域20之短邊22相平行之Y方向上作複數並排配置，而構成之。The first sensor electrode 30 is, as shown in FIG. 2A, a plurality of island-shaped electrodes 31 arranged in the X direction parallel to the long side 21 of the sensor region 20 through the connecting portion 32 The electrode rows 33 formed by connection are arranged in plural in parallel in the Y direction parallel to the short side 22 of the sensor region 20.

第2感測器電極40，係如同圖2B中所示一般，將使被配列在Y方向上之複數之島狀電極41藉由連結部42而被作連結所成的電極列43，在X方向上作複數並排配置，而構成之。The second sensor electrode 40 is, as shown in FIG. 2B, an electrode row 43 formed by connecting a plurality of island-shaped electrodes 41 arranged in the Y direction by a connecting portion 42 at X The plural are arranged side by side in the direction to constitute it.

此些之第1感測器電極30以及第2感測器電極40，係分別藉由細線之網格而被形成，電極列33和43，係以相互被作了絕緣的狀態而相交叉，連結部32和42係位置在相互重疊之位置處。The first sensor electrode 30 and the second sensor electrode 40 are formed by a grid of thin lines, respectively, and the electrode rows 33 and 43 cross each other in an insulated state. The connecting portions 32 and 42 are located at positions overlapping each other.

從第1感測器電極30之各電極列33的X方向兩端，係分別被導出有第2導出配線51，從第2感測器電極40之各電極列43的Y方向其中一端，係分別被導出有第1導出配線52。被作複數配列並從感測器區域20所被導出之第1導出配線52以及第2導出配線51，在圖1中，係將除了位置在配列之兩端處者以外的圖示作省略。From both ends of each electrode row 33 of the first sensor electrode 30 in the X direction, second lead wires 51 are respectively drawn, and from one end of each electrode row 43 of the second sensor electrode 40 in the Y direction, it is The first lead wires 52 are derived respectively. The first lead-out wiring 52 and the second lead-out wiring 51 which are arranged in plural and are derived from the sensor region 20 are omitted in FIG. 1 except for the positions at both ends of the arrangement.

在成為矩形狀的透明基板10之其中一方之長邊的中央部分處，係被配列形成有端子部53，第1導出配線52以及第2導出配線51係分別一直延伸至端子部53處並與端子部53作連接。以包圍感測器區域20、第1導出配線52以及第2導出配線51的方式而被形成於透明基板10之周緣部處的接地配線54，亦係被與端子部53作連接。At the central portion of one of the long sides of the rectangular transparent substrate 10, terminal portions 53 are arranged and arranged, and the first lead-out wiring 52 and the second lead-out wiring 51 extend up to the terminal portion 53 respectively and The terminal 53 is connected. The ground wiring 54 formed at the peripheral portion of the transparent substrate 10 so as to surround the sensor region 20, the first lead wiring 52, and the second lead wiring 51 is also connected to the terminal portion 53.

第1導出配線52、第2導出配線51以及端子部53，係藉由第1導體層而被形成，接地配線54，係被形成於第1以及第2導體層之雙方處。The first lead-out wiring 52, the second lead-out wiring 51, and the terminal portion 53 are formed by the first conductor layer, and the ground wiring 54 is formed at both the first and second conductor layers.

具備有上述一般之構成的第1以及第2導體層，在此例中係成為使用包含有銀等之導電粒子的導電墨水，並藉由凹版膠印(gravure offset)印刷而被作印刷形成者。The first and second conductor layers having the above-mentioned general configuration are used in this example as conductive ink using conductive particles containing silver or the like, and are printed by gravure offset printing.

另外，在觸控面板中，當將電極圖案或配線圖案使用包含有銀等之導電粒子之導電墨水來進行印刷形成的情況時，為了不會對於觸控面板所被作配置之顯示部的視覺辨認性有所損害，將位置在感測器區域中之感測器電極設為具備有高的光透過效率並且難以被視覺辨認到一事係為重要，因此，如同上述之觸控面板一般地，使用導電墨水而印刷形成的感測器電極，一般而言係成為藉由細線之網格所構成者。In addition, in the touch panel, when the electrode pattern or the wiring pattern is printed and formed using conductive ink containing conductive particles such as silver, in order not to visualize the display portion where the touch panel is arranged Recognition is impaired. It is important to set the sensor electrode located in the sensor area to have high light transmission efficiency and difficult to be visually recognized. Therefore, like the above-mentioned touch panel, Sensor electrodes printed using conductive ink are generally made up of a grid of thin lines.

另一方面，就算是如此這般地藉由細線之網格來構成感測器電極，也無法避免起因於細線之網格有所存在的部分和並未存在的部分所產生的視覺性的對比之發生，此種對比，係成為對於顯示部之視覺辨認性造成有一定程度的影響。On the other hand, even if the sensor electrode is formed by a grid of thin lines in this way, the visual contrast between the existing part and the non-existing part of the thin line grid cannot be avoided. As a result, this contrast has a certain impact on the visibility of the display.

關於此點，在上述之觸控面板中，由於第1感測器電極30和第2感測器電極40係使連結部32和42位置在相互重疊之位置處並以使電極列33和43相互交叉的方式而被作配置，亦即是，第2導體層之島狀電極41，係成為於第1導體層中之並未存在有細線之網格的位置處，以將該位置作填埋的方式而被作配置的構成，因此，在第1導體層處所發生的對比和在第2導體層處所發生的對比，係以相互抵消的方式而作用，藉由此，感測器區域之對比度係成為被作降低。In this regard, in the above-mentioned touch panel, since the first sensor electrode 30 and the second sensor electrode 40 are such that the positions of the connecting portions 32 and 42 overlap each other and the electrode rows 33 and 43 They are arranged in such a way as to cross each other, that is, the island-shaped electrode 41 of the second conductor layer is formed at a position in the first conductor layer where there is no grid with thin lines, to fill in this position It is configured to be buried so that the contrast that occurs at the first conductor layer and the contrast that occurs at the second conductor layer act in a way that cancels each other out. The contrast is reduced.

然而，在第1導體層和第2導體層之間，由於係存在有絕緣層，因此，第2導體層之視覺性的對比、和中介有絕緣層之第1導體層之視覺性的對比，係並非為相同，關於此點，在先前技術之觸控面板中，係成為並未對於感測器區域之對比度完全消除的狀態。However, between the first conductor layer and the second conductor layer, since there is an insulating layer, the visual contrast between the second conductor layer and the first conductor layer with the insulating layer in between, This is not the same. In this regard, in the touch panel of the prior art, the contrast of the sensor area is not completely eliminated.

本發明，係有鑑於此種狀況，而以提供一種成為能夠將感測器區域之對比度完全消除並在此觀點上並不具有對於顯示部之視覺性的影響而具備優良之品質的觸控面板一事，作為目的。In view of this situation, the present invention is to provide a touch panel that can completely eliminate the contrast of the sensor area and does not have an effect on the visibility of the display portion from this point of view, and has excellent quality.

In addition, this touch panel is different from the touch panel of the prior art example shown in FIG. 1 in the configuration of the sensor region 20, and the configuration outside the sensor region 20 is basically the same as The configuration shown in Fig. 1 is the same. Figures 3 to 5 show the details of the position corresponding to the upper left part in Figure 1.

圖3，係為對於第1層62之印刷配線的詳細內容作展示者，在感測器區域20處，係被形成有第1感測器電極70和第1假配線80。第1感測器電極70，係將使被配列在X方向上之複數之島狀電極71藉由連結部72而被作連結所成的電極列73，在Y方向上作複數並排配置，而構成之，第1假配線80，係在感測器區域20中，於第1感測器電極70所被作設置之區域以外的區域處，與第1感測器電極70相互絕緣地而被作設置。FIG. 3 shows the details of the printed wiring of the first layer 62. In the sensor area 20, the first sensor electrode 70 and the first dummy wiring 80 are formed. The first sensor electrode 70 is an electrode row 73 formed by connecting a plurality of island-shaped electrodes 71 arranged in the X direction through a connecting portion 72, and arranged in a plural number in the Y direction, and In the configuration, the first dummy wiring 80 is insulated from the first sensor electrode 70 in a region other than the region where the first sensor electrode 70 is provided in the sensor region 20 Make settings.

第1感測器電極70和第1假配線80，均係藉由細線之網格所構成，此些之第1感測器電極70和第1假配線80，係於該些之間被形成有第1空隙91地而被作配置，並且構成身為單一之連續的周期性網格圖案之第1網格圖案90。被包含於第1網格圖案90中之細線，係在與第1空隙91相交叉之場所處被作斷絕。第1網格圖案90之單位格子，在此例中，係被設為1邊之長度為400μm的菱形，構成網格的細線之線寬幅，係被設為7μm。另外，將第1感測器電極70和第1假配線80作絕緣的第1空隙91，係被設為20μm程度。在圖3中，係將此第1空隙91相對性地作擴大展示。The first sensor electrode 70 and the first dummy wiring 80 are both composed of a grid of thin lines, and the first sensor electrode 70 and the first dummy wiring 80 are formed between these The first gap 91 is arranged so as to constitute the first grid pattern 90 which is a single continuous periodic grid pattern. The thin line included in the first grid pattern 90 is cut off at a place crossing the first gap 91. The unit grid of the first grid pattern 90 is, in this example, a diamond with a length of 400 μm on one side, and the line width of the thin lines constituting the grid is set to 7 μm. In addition, the first gap 91 that insulates the first sensor electrode 70 and the first dummy wiring 80 is set to about 20 μm. In FIG. 3, the first gap 91 is relatively enlarged.

另一方面，圖4，係為對於第2層64之印刷配線的詳細內容作展示者，在感測器區域20處，係被形成有第2感測器電極100和第2假配線110。第2感測器電極100，係將使被配列在Y方向上之複數之島狀電極101藉由連結部102而被作連結所成的電極列103，在X方向上作複數並排配置，而構成之，第2假配線110，係在感測器區域20中，於第2感測器電極100所被作設置之區域以外的區域處，與第2感測器電極100相互絕緣地而被作設置。On the other hand, FIG. 4 shows the details of the printed wiring of the second layer 64, and the second sensor electrode 100 and the second dummy wiring 110 are formed in the sensor area 20. In the second sensor electrode 100, a plurality of island-shaped electrodes 101 arranged in the Y direction are connected by a connecting portion 102, and a plurality of electrode rows 103 are arranged side by side in the X direction, and In the configuration, the second dummy wiring 110 is insulated from the second sensor electrode 100 in a region other than the region where the second sensor electrode 100 is provided in the sensor region 20 Make settings.

第2感測器電極100和第2假配線110，均係藉由細線之網格所構成，此些之第2感測器電極100和第2假配線110，係於該些之間被形成有第2空隙121地而被作配置，並且構成身為單一之連續的周期性網格圖案之第2網格圖案120。被包含於第2網格圖案120中之細線，係在與第2空隙121相交叉之場所處被作斷絕。第2網格圖案120，在此例中，係被設為與第1網格圖案90相同之網格圖案，構成網格的細線之與感測器區域20之長邊21之間所成的角度，亦係被設為相同。另外，與圖3相同的，係將第2空隙121相對性地作擴大展示。Both the second sensor electrode 100 and the second dummy wiring 110 are formed by a grid of thin lines, and the second sensor electrode 100 and the second dummy wiring 110 are formed between these The second gap 121 is arranged so as to constitute the second grid pattern 120 which is a single continuous periodic grid pattern. The thin line included in the second grid pattern 120 is cut off at a place crossing the second gap 121. The second grid pattern 120, in this example, is set to the same grid pattern as the first grid pattern 90, formed between the thin lines constituting the grid and the long side 21 of the sensor region 20 The angle is also set to the same. In addition, as in FIG. 3, the second gap 121 is relatively enlarged.

圖5，係為對於將圖3中所示之第1層62之印刷配線和圖4中所示之第2層64之印刷配線包夾著絕緣層63地而作了重疊的狀態作展示者，第1層62之第1網格圖案90和第2層64之第2網格圖案120，係以相互在將單位格子之菱形之邊各200μm地作對分的中點處而相互交叉的方式而被作重疊，藉由此，係成為使一邊之長度為200μm的菱形之格子如同圖5中所示一般地在感測器區域20之全面上極為均勻地被形成的狀態。另外，第1感測器電極70之電極列73和第2感測器電極100之電極列103，係使連結部72和102位置在相互重疊之位置處而相互交叉。FIG. 5 is a diagram showing a state where the printed wiring of the first layer 62 shown in FIG. 3 and the printed wiring of the second layer 64 shown in FIG. 4 are overlapped with the insulating layer 63 therebetween , The first grid pattern 90 of the first layer 62 and the second grid pattern 120 of the second layer 64 intersect each other at a midpoint that bisects the diamond sides of the unit grid at 200 μm each It is overlapped, and by this, a diamond-shaped lattice with a length of 200 μm on one side is formed in a state where it is extremely uniformly formed over the entire area of the sensor region 20 as shown in FIG. 5. In addition, the electrode row 73 of the first sensor electrode 70 and the electrode row 103 of the second sensor electrode 100 are such that the connection portions 72 and 102 cross each other at positions where they overlap each other.

如同上述一般，若依據本例，則在第1感測器電極70所被形成之第1層62的感測器區域20處，第1網格圖案90係成為均一地存在的狀態，在第2感測器電極100所被形成之第2層64的感測器區域20處，第2網格圖案120係成為均一地存在的狀態。故而，在第1層62以及第2層64之兩者中，係均不會發生起因於細線之網格之有無所導致的視覺性之對比，就算是在使第1層62和第2層64作了重疊的狀態下，亦當然並不會發生視覺性的對比，而成為能夠將感測器區域20之對比度完全地消除者。故而，係並不會對於顯示部造成視覺性的影響，而能夠得到在美觀性上係為佳之優良品質的觸控面板。As described above, according to this example, at the sensor region 20 of the first layer 62 where the first sensor electrode 70 is formed, the first grid pattern 90 is in a uniformly existing state. 2 In the sensor region 20 of the second layer 64 where the sensor electrode 100 is formed, the second grid pattern 120 is in a uniformly existing state. Therefore, in both the first layer 62 and the second layer 64, there will be no visual contrast caused by the presence or absence of the grid of thin lines, even if the first layer 62 and the second layer In the state where 64 is overlapped, of course, visual contrast does not occur, and it becomes a person who can completely eliminate the contrast of the sensor region 20. Therefore, there is no visual impact on the display portion, and a touch panel with excellent quality which is excellent in aesthetics can be obtained.

另外，第1網格圖案90和第2網格圖案120，由於係如同上述一般地以在將菱形之邊各200μm地作對分的中點處而交叉的方式而被作重疊，因此，構成第1網格圖案90之細線和構成第2網格圖案120之細線係並不會相互接近，故而，也不會發生像是相互作了接近的細線之組看起來像是一條的粗線一般之描繪出可視覺辨認到的相對性而言為明顯之線的情形。In addition, the first grid pattern 90 and the second grid pattern 120 are overlapped in such a manner that they intersect at the midpoint of the diamond-shaped sides of 200 μm each as described above. 1 The thin lines of the grid pattern 90 and the thin lines constituting the second grid pattern 120 are not close to each other, and therefore, it does not happen that the group of thin lines made close to each other looks like a thick line. Draw a visually recognizable line of relativity.

第1層62之印刷配線和第2層64之印刷配線，在上述之例中，係成為在基體61之其中一面側處包夾著絕緣層63地而被形成者，但是，第1層62之印刷配線和第2層64之印刷配線，係亦可設為分別被形成在基體61之其中一面側和另外一面側處的構成。圖6B，係為對於此構成作展示者，針對與圖6A相對應之部分，係附加有相同之元件符號。圖6B中，67係代表保護膜。另外，基體61係被設為絕緣體。In the above example, the printed wiring of the first layer 62 and the printed wiring of the second layer 64 are formed by sandwiching the insulating layer 63 on one side of the base 61, but the first layer 62 The printed wiring of the second layer 64 and the printed wiring of the second layer 64 may be formed on one side and the other side of the base 61, respectively. FIG. 6B is a display for this configuration, and the same symbol is attached to the part corresponding to FIG. 6A. In FIG. 6B, 67 represents the protective film. In addition, the base 61 is an insulator.

於此，針對被形成在第1感測器電極70所被作設置之第1層62處的第1網格圖案以及被形成在第2感測器電極100所被作設置之第2層64處的第2網格圖案，更進而作詳細說明。Here, for the first grid pattern formed on the first layer 62 where the first sensor electrode 70 is provided and the second layer 64 formed on the second sensor electrode 100 being provided The second grid pattern at the location will be described in more detail.

第1網格圖案和第2網格圖案，係均被設為將1種類的單位格子作為配列要素而藉由依循於一對之配列周期方向的平面填充所得到的格子圖案，一對之配列周期方向，係相互為非平行，在一對之配列周期方向之各者所定義之方向上，係產生有單位格子之與該配列周期方向相對應的並進周期，第1網格圖案和第2網格圖案，係將一對之配列周期方向和與該些分別相互對應的並進周期相互設為相等。Both the first grid pattern and the second grid pattern are set as a grid pattern obtained by filling a plane in the direction of a pair of alignment cycles with one type of unit grid as the alignment element. The periodic direction is non-parallel to each other. In the direction defined by each of the paired arranging periodic directions, a parallel period corresponding to the arranging periodic direction of the unit lattice is generated, the first grid pattern and the second In the grid pattern, the direction of the paired arrangement period and the parallel periods corresponding to these are equal to each other.

第1網格圖案和第2網格圖案，係以具備有特定之偏差的方式而被作對位並重疊。在上述之例中，第1網格圖案和第2網格圖案之單位格子，係以在將被設為一邊之長度為400μm之菱形的菱形之邊各200μm地作對分的中點處而交叉的方式，來使第1網格圖案和第2網格圖案被作重疊，亦即是，第1網格圖案和第2網格圖案，係以在一對之配列周期方向的雙方之各者中具備有與該配列周期方向相對應的並進周期之1/2周期之偏差的方式而被作對位並重疊。藉由此，來成為使構成第1網格圖案和第2網格圖案之細線彼此以最大的間隔來相互分離，並且成為在被作了重疊的狀態下一邊之長度為200μm的菱形會被均一地形成，但是，在第1網格圖案和第2網格圖案之重疊中，係只要以在一對之配列周期方向的雙方之各者中具備有與該配列周期方向相對應的並進周期之1/4周期以上3/4周期以下之範圍之偏差的方式來作對位即可，藉由此，係能夠充分地避免由重疊所導致的細線彼此之接近。The first grid pattern and the second grid pattern are aligned and overlapped with a specific deviation. In the above example, the unit grids of the first grid pattern and the second grid pattern intersect at the midpoint of the rhombus that is set to a side with a length of 400 μm, each of which is divided by 200 μm. The first grid pattern and the second grid pattern are overlapped, that is, the first grid pattern and the second grid pattern are arranged in a pair of the two in the periodic direction It is aligned and overlapped in such a way that a deviation of 1/2 of the parallel period corresponding to the direction of the arrangement period is provided. By this, the thin lines constituting the first grid pattern and the second grid pattern are separated from each other at the maximum interval, and in the overlapped state, the rhombus with a length of 200 μm on one side is uniformized However, in the overlapping of the first grid pattern and the second grid pattern, it is only necessary to have a parallel period corresponding to the arrangement period direction in each of the pair of arrangement period directions in a pair The alignment may be performed in a manner of deviation within the range of 1/4 cycle to 3/4 cycle, and by this, it is possible to sufficiently avoid the proximity of the thin lines caused by overlap.

單位格子，在上述之例中，係被設為菱形，但是，係並不被限定於此，而可採用多樣化的形狀。例如，單位格子之形狀，係亦可為正方形或正六角形。此些之格子圖案之一對之配列周期方向之相對角度，在正方形中係成為90°，在正六角形中係成為60°。又，並進周期，係成為相互平行之相對向之邊的彼此之間隔(在正方形時，係為1邊之長度)。The unit grid is set to a rhombus in the above example, but the system is not limited to this, and various shapes can be adopted. For example, the shape of the unit grid may be square or regular hexagon. The relative angle of the arrangement period direction of one pair of these lattice patterns becomes 90° in squares and 60° in regular hexagons. In addition, the advancing period is the interval between the mutually opposing sides that are parallel to each other (in the case of a square, the length is one side).

圖7A、7B，係分別為對於正方形之格子圖案131、132作展示者，圖7C，係為對於該些之格子圖案131、132為以在一對之配列周期方向之雙方的各者中具備有與該配列周期方向相對應的並進周期之1/2周期之偏差的方式而被作對位並重疊的狀態作展示者。FIGS. 7A and 7B show the square lattice patterns 131 and 132 respectively, and FIG. 7C shows that the lattice patterns 131 and 132 are provided for each of the paired alignment periods. There is a state of alignment and overlap as a presenter in such a manner that the deviation of 1/2 of the parallel period corresponding to the direction of the arrangement period is aligned.

圖8A、8B，係分別為對於正六角形之格子圖案141、142作展示者，圖8C，係為對於該些之格子圖案141、142為以在一對之配列周期方向之雙方的各者中具備有與該配列周期方向相對應的並進周期之1/2周期之偏差的方式而被作對位並重疊的狀態作展示者。FIGS. 8A and 8B show the regular hexagonal lattice patterns 141 and 142 respectively, and FIG. 8C shows the lattice patterns 141 and 142 of the hexagonal lattice patterns in the pairing direction. The presenter is provided with a state of being aligned and overlapping with a deviation of 1/2 of the parallel period corresponding to the direction of the arrangement period.

進而，單位格子之形狀，係亦可為長方形或平行四邊形，又，亦可為被3組之相互平行之相對向之邊所包圍的相對向之2邊間之間隔並非為相同之六角形。Furthermore, the shape of the unit grid may be a rectangle or a parallelogram, or the interval between two opposing sides surrounded by three sets of opposing sides that are parallel to each other may not be the same hexagon.

圖9，係為對於單位格子為長方形之格子圖案151、152被作了重疊的狀態作展示者，圖10，係為對於具備有被3組之相互平行之相對向之邊所包圍的相對向之2邊間之間隔之其中一者為窄的橫方向為長之六角形之單位格子的格子圖案161、162被作了重疊的狀態作展示者。Fig. 9 is a display for the state in which the lattice patterns 151 and 152 in which the unit lattice is rectangular are overlapped, and FIG. 10 is for the opposite direction surrounded by three sets of mutually opposite edges that are parallel to each other. One of the intervals between the two sides is a narrow hexagonal unit lattice pattern 161, 162 in which the horizontal direction is superimposed, and it is exhibited.

在此些之圖9以及圖10中所例示一般之多樣化的形狀之單位格子，係可藉由對於正方形或正六角形之單位格子或者是藉由該單位格子所成的格子圖案而進行下述(1)或(2)之圖形轉換操作，來得到之。The general unit cell of various shapes illustrated in FIG. 9 and FIG. 10 can be performed by a square or regular hexagonal unit cell or a lattice pattern formed by the unit cell as follows (1) or (2) graphics conversion operation to get it.

(1)使平面內之任意之一個方向作向異性伸縮的圖形轉換 (2)轉換為「將平面內之任意所定義的第1斜交座標系中之圖形的各點之座標值，代入至具備有與第1斜交座標系相異之座標軸間角度的任意之第2斜交座標系中，所得到的圖形」之圖形轉換(1) Convert the graphic in any direction in the plane to anisotropic expansion and contraction (2) Convert to "the coordinate value of each point of the graphic in the first oblique coordinate system defined in the plane, substitute into Graphic conversion of any second oblique coordinate system with an angle between coordinate axes different from the first oblique coordinate system"

例如，藉由(1)之操作，正方形係成為長方形或菱形、平行四邊形，藉由(2)之操作，正方形係成為菱形。又，正六角形，係藉由(1)或(2)之操作，而成為被3組之相互平行之相對向之邊所包圍的相對向之2邊間之間隔並非為相同之六角形。For example, by the operation of (1), the square becomes a rectangle or a rhombus, a parallelogram, and by the operation of (2), the square becomes a rhombus. In addition, the regular hexagon is formed by the operation of (1) or (2), and the interval between the opposing two sides surrounded by the three opposing sides that are parallel to each other is not the same hexagon.

另外，單位格子，在上述記載中，雖係成為將4個或6個的頂點藉由以直線所成之邊來作連結並將內部作了包圍的形狀，但是，係亦可設為將4個或6個的頂點藉由曲線或以直線和曲線所成之邊來作連結並將內部作了包圍的形狀。In addition, in the above description, the unit grid has a shape in which four or six vertices are connected by edges formed by straight lines and surrounds the interior. However, the unit grid can also be set to 4 One or six vertices are connected by a curve or an edge formed by a straight line and a curve, and the interior is surrounded by a shape.

此種形狀之單位格子，係可藉由對於正方形或正六角形之單位格子而進行下述(3)之操作，來得到之。The unit cell of this shape can be obtained by performing the following operation (3) for the unit cell of square or regular hexagon.

(3)將相互平行之相對向之邊的線段，一同置換為相同之曲線或者是以曲線和直線之結合所成之線(3) Replace the line segments of opposite sides parallel to each other with the same curve or a line formed by the combination of curve and straight line

圖11，係為對於使具備有對正方形之單位格子而進行了(3)的操作之單位格子的格子圖案171、172被作了重疊的狀態作展示者，圖12，亦係為對於使具備有對正方形之單位格子而進行了(3)的操作之單位格子的格子圖案181、182被作了重疊的狀態作展示者。另外，圖13A，係為對於對正方形之單位格子而進行了(3)的操作所得到之單位格子190的形狀例更進而作展示者，圖13B，係為對於對正六角形之單位格子而進行了前述(1)的操作所得到之單位格子200的形狀例更進而展示者。FIG. 11 is a display for the state in which the lattice patterns 171 and 172 of the unit grid provided with the unit grid for square operation (3) are overlapped, and FIG. 12 is also for the display of As a presenter, the lattice patterns 181 and 182 of the unit lattice where the operation of (3) was performed on the square unit lattice were overlapped. In addition, FIG. 13A shows an example of the shape of the unit grid 190 obtained by performing the operation of (3) on the square unit grid, and FIG. 13B shows the shape of the unit grid aligned with the regular hexagon. The shape example of the unit grid 200 obtained by the above operation (1) is further demonstrated.

能夠將1種類的單位格子依循相互非平行之一對之配列周期方向以及與該些分別相互對性之並進周期而並行前進的操作來進行平面填充之單位格子或者是以該單位格子所成之格子圖案，係亦可將上述(1)～(3)之操作作複合性的進行，來得到之。Unit grids that can be plane-filled according to the arrangement period direction of a pair of unit grids that are not parallel to each other and the parallel cycles of these mutually opposite parallel cycles, or a unit grid formed by the unit grid The lattice pattern can also be obtained by performing the above operations (1) to (3) in a complex manner.

另外，第1網格圖案和第2網格圖案，只要單位格子之配列周期方向與並進周期係相互一致，則單位格子的形狀自身係並非絕對需要相互一致。例如，第2網格圖案之單位格子，係亦可為對於第1網格圖案之單位格子而進行了上述(3)之操作者。In addition, as long as the arrangement period direction of the unit grid and the parallel period system coincide with each other in the first grid pattern and the second grid pattern, the shape itself of the unit grid does not necessarily need to coincide with each other. For example, the unit grid of the second grid pattern may be the operator who performed the above (3) for the unit grid of the first grid pattern.

以上，雖係針對被形成於第1層62處之第1網格圖案以及被形成於第2層64處之第2網格圖案而作了說明，但是，此些之第1網格圖案以及第2網格圖案，係如同前述一般地，為了將感測器區域20之對比消除，而分別位置在感測器區域20之全部區域處，在圖6A中所示之層構成之觸控面板的情況時，第1感測器電極70和第2假配線110係包夾著絕緣層63而相互重疊，同樣的，第2感測器電極100和第1假配線80係成為包夾著絕緣層63而相互重疊。In the above, the first grid pattern formed at the first layer 62 and the second grid pattern formed at the second layer 64 have been described. However, these first grid patterns and The second grid pattern is, as described above, in order to eliminate the contrast of the sensor area 20, and is located at all areas of the sensor area 20, respectively, in the touch panel composed of the layers shown in FIG. 6A In the case of the case, the first sensor electrode 70 and the second dummy wiring 110 overlap each other with the insulating layer 63 interposed therebetween. Similarly, the second sensor electrode 100 and the first dummy wiring 80 become sandwiched with the insulation The layers 63 overlap each other.

接著，針對藉由第2層64所形成之第2感測器電極100、和在感測器區域20之周圍的邊框區域處而藉由第1層62所形成的第1導出配線52，此兩者間之連接部分作說明。Next, for the second sensor electrode 100 formed by the second layer 64 and the first lead wiring 52 formed by the first layer 62 at the frame area around the sensor area 20, this The connection between the two is explained.

圖14，係為對於此連接部分作展示者，在第1導出配線52之前端處，係被形成有由細線之細密之網格所成的第1連接部52a。另一方面，在第2感測器電極100之端緣處，係被延長形成有延長部104。延長部104，在此例中，係由使構成第2感測器電極100之網格作了延長的大網格部104a、和從大網格部104a起而更進而作了延長形成的小網格部104b，而構成之。小網格部104b，係被設為細線之細密的網格，此小網格部104b和第1導出配線52之第1連接部52a，係成為具備有單位格子為正方形之同一之網格構造者。FIG. 14 is a display of this connection portion. At the front end of the first lead-out wiring 52, a first connection portion 52a made of a fine mesh of fine lines is formed. On the other hand, an extension 104 is formed at the end of the second sensor electrode 100. The extension portion 104 is, in this example, a large mesh portion 104a that extends the mesh constituting the second sensor electrode 100, and a small portion that is further extended from the large mesh portion 104a The mesh portion 104b is constituted. The small mesh portion 104b is a fine mesh with a thin line. The small mesh portion 104b and the first connection portion 52a of the first lead-out wiring 52 have the same mesh structure with a unit grid as a square By.

在絕緣層63處，係被形成有第1貫通孔63a，第1導出配線52之第1連接部52a和第2感測器電極100之延長部104，係位置於此第1貫通孔63a中，並相互被作接觸導通，藉由此，第1導出配線52係被與第2感測器電極100作連接。另外，具備有同一之網格構造的第1連接部52a和小網格部104b，在此例中，係如同圖14中所示一般，以具備有1/2節距(1/2周期)之偏差的方式而被作對位並重疊。At the insulating layer 63, a first through hole 63a is formed, the first connection portion 52a of the first lead-out wiring 52 and the extension portion 104 of the second sensor electrode 100 are located in the first through hole 63a And are connected to each other in contact, whereby the first lead-out wiring 52 is connected to the second sensor electrode 100. In addition, the first connection portion 52a and the small mesh portion 104b having the same mesh structure are provided, in this example, as shown in FIG. 14, to have a 1/2 pitch (1/2 cycle) The deviations are aligned and overlapped.

另一方面，在與第2感測器電極100包夾著絕緣層63地而相互重疊之第1假配線80(在圖14中係以虛線作標示)的邊緣處，在此例中，係被設置有使細線之網格作了缺損的第1凹部81，藉由此第1凹部81，第1假配線80之邊緣係從第1貫通孔63a而分離。藉由設置此種第1凹部81，在此例中，係成為能夠避免起因於第1假配線80與第2感測器電極100相接觸一事所發生的問題者。On the other hand, at the edge of the first dummy wiring 80 (indicated by a broken line in FIG. 14) overlapping the second sensor electrode 100 with the insulating layer 63 interposed therebetween, in this example, The first concave portion 81 in which the mesh of the thin line is damaged is provided. With the first concave portion 81, the edge of the first dummy wiring 80 is separated from the first through hole 63a. By providing such a first concave portion 81, in this example, it is possible to avoid a problem caused by the contact between the first dummy wiring 80 and the second sensor electrode 100.

亦即是，若是起因於在第1層62、絕緣層63以及第2層64之印刷中所發生的印刷偏差或暈滲而導致第1假配線80從絕緣層63之邊緣而超出、亦即是超出至第1貫通孔63a內，並與第2感測器電極100之延長部104作接觸導通，則會發生該第1假配線80所作了接觸導通的第2感測器電極100之靜電電容產生顯著的變化之問題。相對於此，藉由在第1假配線80處，設置使其之邊緣從第1貫通孔63a而分離的第1凹部81，由於係被形成有確保有該第1凹部81之尺寸之量的絕緣之間隙，因此，就算是在印刷中發生有該尺寸以內之的印刷偏差或暈滲，也能夠避免第1假配線80與第2感測器電極100之接觸導通，故而，係能夠防止第2感測器電極100之靜電電容產生變化之問題的發生。另外，在圖14中所示之第1凹部81的尺寸d₁ 、d₂ ，例如係設為確保有160μm之程度者。That is, if the printing error or blooming occurs in the printing of the first layer 62, the insulating layer 63, and the second layer 64, the first dummy wiring 80 exceeds the edge of the insulating layer 63, that is, If it extends beyond the first through hole 63a and makes contact with the extension 104 of the second sensor electrode 100, the static electricity of the second sensor electrode 100 with the first dummy wiring 80 in contact with it will occur The problem of significant changes in capacitance. On the other hand, by providing the first dummy wiring 80 with a first recess 81 whose edge is separated from the first through hole 63a, the amount of the size of the first recess 81 is ensured The gap between the insulation, therefore, even if printing deviation or blooming within this size occurs during printing, the contact conduction between the first dummy wiring 80 and the second sensor electrode 100 can be avoided, so the first 2 The problem that the electrostatic capacitance of the sensor electrode 100 changes. In addition, the dimensions d ₁ and d ₂ of the first recess 81 shown in FIG. 14 are, for example, such that they are 160 μm.

圖15，係為對於第1感測器電極70和第2導出配線51之連接部分作展示者。在第2導出配線51之前端處，係與第1導出配線52之第1連接部52a相同的，被形成有由細線之細密之網格所成的第2連接部51a，經由此第2連接部51a，第1感測器電極70和第2導出配線51係被作連接。FIG. 15 shows a connection part between the first sensor electrode 70 and the second lead-out wiring 51. At the front end of the second lead-out wiring 51, it is the same as the first connection portion 52a of the first lead-out wiring 52, and is formed with a second connection portion 51a made of a fine mesh of thin wires, and is connected via this second connection The portion 51a, the first sensor electrode 70 and the second lead-out wiring 51 are connected.

第1感測器電極70、第2導出配線51以及第2連接部51a，係藉由相同之第1層62而被形成，故而，第2連接部51a係成為被絕緣層63所覆蓋，但是，例如在將被與第1感測器電極70之端緣作連結的第2連接部51a作為用以進行第1感測器電極70之電性檢查之檢查用墊片來使用的情況時，係如同圖15中所示一般，在絕緣層63處，係被設置有使第2連接部51a露出之第2貫通孔63b。於此情況，係可能會發生與前述之第2感測器電極100和第1導出配線52之間之連接部分相同的問題。故而，在與第1感測器電極70包夾著絕緣層63地而相互重疊之第2假配線110(在圖15中係以虛線作標示)的邊緣處，係設置使第2假配線110之邊緣從第2貫通孔63b而分離之第2凹部111。The first sensor electrode 70, the second lead-out wiring 51, and the second connection portion 51a are formed by the same first layer 62, so the second connection portion 51a is covered by the insulating layer 63, but For example, when the second connection portion 51a connected to the edge of the first sensor electrode 70 is used as an inspection pad for electrical inspection of the first sensor electrode 70, As shown in FIG. 15, the insulating layer 63 is provided with a second through hole 63b that exposes the second connection portion 51a. In this case, the same problem as the connection portion between the second sensor electrode 100 and the first lead-out wiring 52 described above may occur. Therefore, at the edge of the second dummy wiring 110 (indicated by a broken line in FIG. 15) overlapping the first sensor electrode 70 with the insulating layer 63 interposed therebetween, the second dummy wiring 110 is provided The second concave portion 111 whose edge is separated from the second through hole 63b.

藉由如此這般地設置第2凹部111，係能夠防止起因於印刷偏差或暈滲而導致第2假配線110超出至第2貫通孔63b內並與第2連接部51a作接觸導通並且造成第1感測器電極70之靜電電容產生變化之問題的發生。另外，在圖15中所示之第2凹部111的尺寸d₁ 、d₂ ，係設為與第1凹部81相同之值。By providing the second concave portion 111 in this way, it is possible to prevent the second dummy wiring 110 from exceeding the second through hole 63b due to printing deviation or blooming and making contact with the second connection portion 51a and causing the first 1. The problem that the electrostatic capacitance of the sensor electrode 70 changes. In addition, the dimensions d ₁ and d ₂ of the second recess 111 shown in FIG. 15 are set to the same values as the first recess 81.
