Abstract

An infrared data communication having infrared data communication part set on lower part of architrave of front panel of touch panel sensor is carried out, through without setting the window for infrared data communication formed by an infrared transparency film on the architrave part. By using a material absorbing visible light and transmitting infrared ray to form the architrave part of front panel, wiring is hidden, meanwhile, it is unnecessary to set the window for infrared data communication on the architrave part. Thus not only it can prevent from increase of steps and cost, but also can eliminate the poor condition caused by difference in level due to the infrared transparency film formed on the architrave part.

Description

觸控面板用前面板、具備該前面板之顯示裝置、以及觸控面板用前面板與觸控面板感測器之一體型感測器基板 a front panel for a touch panel, a display device having the front panel, and a body sensor substrate of the front panel and the touch panel sensor of the touch panel

本發明關於顯示裝置用之觸控面板用前面板，更詳細地關於在周邊部上具備框緣部之觸控面板用前面板。 The present invention relates to a front panel for a touch panel for a display device, and more particularly to a front panel for a touch panel having a frame portion at a peripheral portion thereof.

近年來，於行動電話機或行動資訊終端等的電子機器之操作部中，採用觸控面板。觸控面板係在液晶面板或有機EL(Electro-Luminesence)等的顯示裝置之顯示畫面上，貼合可檢測出手指等的接觸位置之位置輸入裝置而構成。作為觸控面板之方式，大致區分為電阻膜式、靜電容量式、光學式、超音波式，由於各自具有優點/缺點，按照用途來靈活運用。於靜電容量式中，更有表面型與投影型。投影型靜電容量式觸控面板係在X方向及Y方向中具備排列成柵格上的複數之電極，而可多點觸控，現在正在急速普及中。 In recent years, a touch panel has been used in an operation unit of an electronic device such as a mobile phone or a mobile information terminal. The touch panel is configured by attaching a position input device that can detect a contact position of a finger or the like on a display screen of a display device such as a liquid crystal panel or an organic EL (Electro-Luminesence). As a method of the touch panel, it is roughly classified into a resistive film type, an electrostatic capacitance type, an optical type, and an ultrasonic type, and each has its advantages and disadvantages, and is flexibly used according to the use. In the electrostatic capacity type, there are more surface type and projection type. The projection type electrostatic capacitance type touch panel has a plurality of electrodes arranged in a grid on the grid in the X direction and the Y direction, and is multi-touch, and is now rapidly spreading.

於投影型靜電容量式的觸控面板感測器基板中，有薄膜型與玻璃型。薄膜型雖然具有輕量‧不易破裂之優點，但高精細的配線圖案之形成困難，覆蓋配線的框緣部變大，有顯示範圍變窄之問題，或由於表面的平滑性差，而美觀上比玻璃型差之問題。於智慧型手機或平板電腦中，多採用玻璃型，今後預料玻璃型之普及。 In the projection type electrostatic capacitance type touch panel sensor substrate, there are a film type and a glass type. Although the film type has the advantages of being lightweight and not easily broken, the formation of a high-definition wiring pattern is difficult, the frame edge portion covering the wiring becomes large, the display range is narrowed, or the smoothness of the surface is poor, and the appearance is beautiful. The problem of poor glass type. In the smart phone or tablet, the glass type is mostly used, and the popularity of the glass type is expected in the future.

投影型靜電容量式觸控面板感測器基板一般係由5層構造所組成，即由金屬配線、X方向用及Y方向用的2層透明電極、2層的透明電極間之層間絕緣層、表面的保護層所組成。又，大致區分為：藉由有機膜來形成層間絕緣層，在玻璃基板的一面上形成有2層透明電極層之單面構造；亦使用玻璃基板作為層間絕緣層，將2層的透明電極層分開地形成在玻璃之兩面上的兩面構造這2種。 The projection type electrostatic capacitance touch panel sensor substrate is generally composed of a five-layer structure, that is, two layers of transparent electrodes for metal wiring, X direction and Y direction, and an interlayer insulating layer between two transparent electrodes. The surface of the protective layer is composed of. Moreover, it is roughly divided into: an interlayer is formed by an organic film The insulating layer has a single-sided structure in which two transparent electrode layers are formed on one surface of the glass substrate, and a two-layer structure in which two transparent TFT layers are separately formed on both surfaces of the glass by using a glass substrate as an interlayer insulating layer. Kind.

此處，於行動電話機等的顯示器中，一般採用在最表面設有前面板(蓋玻璃)之構造。於此蓋玻璃中，為了隱藏周邊部的配線等，形成由遮光性高之材料所成的框緣部。此框緣部係可按照機器的設計而施予各式各樣的顏色或花樣。於對框緣部施予顏色或花樣時，一般藉由網版印刷來形成框緣部。惟，由於若對框緣部施予各式各樣的顏色或花樣，則與成本之上升有關聯，故框緣部成為黑色者係主流(例如，參照專利文獻1)。 Here, in a display such as a cellular phone, a structure in which a front panel (lid glass) is provided on the outermost surface is generally used. In the cover glass, a frame edge portion made of a material having a high light-shielding property is formed in order to hide wiring or the like in the peripheral portion. This frame edge can be applied to a wide variety of colors or patterns depending on the design of the machine. When a color or a pattern is applied to the edge portion of the frame, the frame portion is generally formed by screen printing. However, when a variety of colors or patterns are applied to the frame edge portion, the frame edge portion becomes a black body (see, for example, Patent Document 1).

作為形成此黑色的框緣部時所使用之油墨或光阻，一般使用分散有碳或鈦作為顏料的材料。分散有碳或鈦之材料係體積電阻率低，比介電常數亦高。又，亦採用藉由樹脂來被覆碳，而使體積電阻率達到1×10¹¹Ω‧cm為止之高電阻化的材料。 As the ink or photoresist used in forming the black frame portion, a material in which carbon or titanium is dispersed as a pigment is generally used. The material in which carbon or titanium is dispersed has a low volume resistivity and a high specific dielectric constant. Further, a material which is coated with carbon by a resin and has a high electrical resistance until the volume resistivity is 1 × 10 ¹¹ Ω ‧ cm is also used.

於行動電話機等中，具備用於與其它行動電話機等進行紅外線通信之紅外線通信部，一般地配置在前面板之有框緣部的區域之下方(行動電話機等的內方)。此係因為框緣部位於顯示範圍之外側，由於比顯示裝置還大地構成，故可在其下方設置將紅外線通信部配置用之空間。 In a mobile phone or the like, an infrared communication unit for performing infrared communication with another mobile phone or the like is provided, and is generally disposed below a region of the front panel having a frame edge portion (inside of a mobile phone or the like). Since the frame edge portion is located outside the display range and is configured to be larger than the display device, a space for arranging the infrared communication portion can be provided below the frame.

第20圖中顯示以往的行動電話機等所使用的觸控面板之蓋玻璃之一例。第20圖中，(a)為截面圖，(b)為平面圖。又，第20圖之(b)所示之雙點畫線表示(a)的截面圖之切斷位置。 Fig. 20 shows an example of a cover glass of a touch panel used in a conventional mobile phone or the like. In Fig. 20, (a) is a cross-sectional view, and (b) is a plan view. Further, the double-dotted line shown in (b) of Fig. 20 indicates the sectional view of (a). Cut off the position.

如第20圖之(a)、(b)所示，於蓋玻璃102上形成矩形框狀的框緣部103，框緣部103的內側係成為顯示區域110。由於如前述之框緣部103係由遮光性高的材料所形成，這樣子可見光或紅外線係不穿透。因此，在框緣部103設置未形成遮光性材料的開口部，如第20圖之(a)、(b)所示，形成紅外線通信用窗140與近接感測器用窗150。 As shown in FIGS. 20(a) and (b), a frame-shaped portion 103 having a rectangular frame shape is formed on the cover glass 102, and the inside of the frame portion 103 is a display region 110. Since the frame edge portion 103 as described above is formed of a material having a high light-shielding property, the sub-visible light or the infrared light does not penetrate. Therefore, an opening portion in which the light-shielding material is not formed is provided in the frame edge portion 103, and as shown in FIGS. 20(a) and (b), the infrared communication window 140 and the proximity sensor window 150 are formed.

未圖示的紅外線通信部係通過紅外線通信用窗140，進行紅外線接收。又，未圖示的近接感測器係通過近接感測器用窗150，當通話時耳朵靠近時等，感知物體接近而將顯示部熄燈，進行節電。此處，如第20圖之(a)、(b)所示，於紅外線通信用窗140中，在紅外線通信用窗140與其周圍的區域，藉由網版印刷等形成紅外線透過膜141。藉由紅外線透過膜141，將自紅外線通信用窗140所入射的可見光予以遮光，使紅外線穿透，進行紅外線通信。又，於近接感測器用窗150中，在近接感測器用窗150與其周圍的區域，藉由網版印刷等形成未圖示的可見範圍之半透過膜。 The infrared communication unit (not shown) receives infrared rays through the infrared communication window 140. Further, the proximity sensor (not shown) passes through the proximity sensor window 150, and when the ear is approaching during a call, the object is sensed to be approached, and the display unit is turned off to save power. Here, as shown in FIGS. 20(a) and (b), in the infrared communication window 140, the infrared ray permeable film 141 is formed by screen printing or the like in the infrared communication window 140 and the surrounding area. The infrared ray permeable film 141 shields visible light incident from the infrared communication window 140, and transmits infrared rays to perform infrared communication. Further, in the proximity sensor window 150, a semi-transmissive film of a visible range (not shown) is formed by screen printing or the like in the vicinity of the sensor window 150 and the surrounding area.

然而，於框緣部103設置紅外線通信用窗140時，由於必須在框緣部103之上形成紅外線透過膜141，故有增加步驟數及製造成本之不良狀況。 However, when the infrared communication window 140 is provided in the frame edge portion 103, Since the infrared ray permeable film 141 must be formed on the frame edge portion 103, there is a problem that the number of steps and the manufacturing cost are increased.

又，如第20圖之(a)所示，若形成紅外線透過膜141，則對於框緣部103之表面而言，發生階差141a。由於此階差141a，前面板厚有變更厚之不良狀況。 Further, as shown in FIG. 20(a), when the infrared ray transmitting film 141 is formed, a step 141a is generated on the surface of the frame edge portion 103. Due to this step 141a, the thickness of the front panel is changed to be thick.

再者，於框緣部103的指定位置上設置紅外線通信用窗140時，紅外線通信部變成配置在其下方。即，有無法將紅外線通信部配置在框緣部103的下方之任意位置的不方便。 In addition, when the infrared communication window 140 is provided at a predetermined position of the frame edge portion 103, the infrared communication portion is disposed below. In other words, there is an inconvenience that the infrared communication unit cannot be disposed at any position below the frame edge portion 103.

Body sensor substrate; In the case where the infrared communication window is provided in the frame edge portion and the infrared ray permeable film is formed, the manufacturing process of the cover glass of the front panel can be simplified, and the display device can also reduce the thickness of the entire thickness by thinning.

再者，由於此顯示裝置係具備至少由紅色系與藍色系、紅色系與藍色系和黃色系的顏料所成之框緣部，當顯示區域為黑顯示時，該框緣部之黑色相，與以往使用分散有碳或鈦作為顏料之材料來形成框緣部的情況相比，因更接近顯示區域的黑顯示之黑色，故框緣部不顯眼，成為品位良好之顯示裝置。 Further, since the display device includes a frame portion formed of at least a red color, a blue color, a red color, a blue color, and a yellow color, when the display area is black, the frame edge portion is black. In the case where the frame edge portion is formed by using a material in which carbon or titanium is dispersed as a pigment, the black portion of the display region is black, and the frame edge portion is inconspicuous, and the display device is excellent in quality.

[實施發明之形態] [Formation of the Invention]

以下，參照圖面，詳細說明本發明之實施形態。 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

(第1實施形態) (First embodiment)

參照第1圖至第7圖，說明本發明的第1實施形態之觸控面板感測器。本實施形態的觸控面板感測器係蓋玻璃與觸模感測器一體直接形成者。又，將金屬配線設置在框緣部而構成。 A touch panel sensor according to a first embodiment of the present invention will be described with reference to Figs. 1 to 7 . The touch panel sensor of the present embodiment is formed directly by the cover glass and the touch sensor. Moreover, the metal wiring is provided in the frame edge portion.

第1圖係本實施形態的觸控面板感測器1之平面圖。第2圖係顯示第1圖所示的觸控面板感測器1之積層構造的詳細之平面圖，顯示第1圖的絕緣保護膜9之形成前的狀態。第3圖係沿著第1圖所示的A-A線之截面圖，第4圖係沿著第1圖所示的B-B線之截面圖。於第1圖~第4圖中，為了將圖示簡略化，在X方向及Y方向的各自方向中，示意地顯示2線的電極圖案，但於實際上，在X方向及Y方向中設有更多的電極。第7圖係顯示在本實施形態的觸控面板感測器上直接貼附顯示裝置而成為一體時之形態，相當於沿著第1圖所示的A-A線之截面圖。 Fig. 1 is a plan view of the touch panel sensor 1 of the present embodiment. 2 is a detailed plan view showing the laminated structure of the touch panel sensor 1 shown in FIG. 1, showing the formation of the insulating protective film 9 of FIG. status. Fig. 3 is a cross-sectional view taken along line A-A shown in Fig. 1, and Fig. 4 is a cross-sectional view taken along line B-B shown in Fig. 1. In the first to fourth figures, in order to simplify the illustration, two-line electrode patterns are schematically displayed in the respective directions of the X direction and the Y direction, but actually, the X direction and the Y direction are set. There are more electrodes. Fig. 7 is a view showing a state in which the display device is directly attached to the touch panel sensor of the present embodiment, and corresponds to a cross-sectional view taken along line A-A shown in Fig. 1.

觸控面板感測器1係與液晶面板21或有機EL面板等之顯示裝置組合使用的位置輸入裝置。觸控面板感測器1具有在X方向中延伸的複數之電極及在Y方向中延伸的複數之電極，藉由檢測手指所接觸或近接的電極之靜電容量變化，而特別定出手指的接觸位置之座標。 The touch panel sensor 1 is a position input device used in combination with a display device such as a liquid crystal panel 21 or an organic EL panel. The touch panel sensor 1 has a plurality of electrodes extending in the X direction and a plurality of electrodes extending in the Y direction, and the contact of the fingers is specifically determined by detecting a change in electrostatic capacitance of the electrodes that are in contact with or in close proximity of the finger. The coordinates of the location.

具體地，觸控面板感測器1具備蓋玻璃2、框緣部3、複數的跨接配線4、第1絕緣膜5、金屬配線6、第1透明電極之複數的透明電極7及第2透明電極之複數的透明電極8、絕緣保護膜9。 Specifically, the touch panel sensor 1 includes a cover glass 2, a frame edge portion 3, a plurality of jumper wires 4, a first insulating film 5, a metal wiring 6, a plurality of transparent electrodes 7 of the first transparent electrode, and a second A plurality of transparent electrodes 8 and an insulating protective film 9 of a transparent electrode.

蓋玻璃2係觸控面板感測器1之最表面的透明前面板，為被使用者所觸摸的構件。於本實施形態中，說明使用蓋玻璃2作為前面板之例，但代替玻璃，亦可使用耐熱性透明樹脂材料作為前面板。又，亦可在玻璃表面上黏貼由樹脂材料所成的透明板，由複數之層所形成。 The cover glass 2 is a transparent front panel on the outermost surface of the touch panel sensor 1 and is a member that is touched by a user. In the present embodiment, an example in which the cover glass 2 is used as the front panel will be described. However, instead of the glass, a heat-resistant transparent resin material may be used as the front panel. Further, a transparent plate made of a resin material may be adhered to the surface of the glass, and formed of a plurality of layers.

框緣部3係使用吸收可見光而且穿透紅外線的紅外線透過材料，形成在蓋玻璃2之一面上。框緣部3所達成的任務為在中央的窗部分區劃指定形狀的顯示區域10,隱藏觸控面板感測器1之周邊部所設置的配線。 The frame edge portion 3 is formed on one surface of the cover glass 2 by using an infrared ray transmissive material that absorbs visible light and penetrates infrared rays. The task achieved by the frame edge portion 3 is to divide the display region 10 of a predetermined shape in the central window portion, and to hide the wiring provided in the peripheral portion of the touch panel sensor 1.

框緣部3係以在蓋玻璃2的周邊部區劃顯示區域10之方式，形成矩形框狀。再者，框緣部3的平面形狀係不受如本實施形態的矩形框狀所限定，可為心型、蛋型、圓型等任意者。又，框緣部3的外周邊形狀(外形)與內周邊形狀(顯示區域10之形狀)可相似或不相似。 The frame edge portion 3 is formed in a rectangular frame shape so as to divide the display region 10 in the peripheral portion of the cover glass 2. Further, the planar shape of the frame edge portion 3 is not limited to the rectangular frame shape of the present embodiment, and may be any of a heart shape, an egg shape, and a round shape. Further, the outer peripheral shape (outer shape) of the frame edge portion 3 and the inner peripheral shape (the shape of the display region 10) may be similar or dissimilar.

如第3圖及第4圖所示，與蓋玻璃2的一面呈正交的框緣部3之切面係順錐型形狀。此處，關於框緣部3的切面之形狀，例如當為倒錐型(倒懸形狀)時，觸控面板感測器1的透明電極7等之配線有斷線之虞。因此，關於框緣部3的切面之形狀，若為順錐型則對於斷線而言變有利。於是，框緣部3係在光阻處方及製程條件下形成順錐型形狀。 As shown in FIGS. 3 and 4, the cut surface of the frame edge portion 3 orthogonal to the one surface of the cover glass 2 has a tapered shape. Here, regarding the shape of the cut surface of the frame edge portion 3, for example, when it is an inverted taper type (inverted-hanging shape), the wiring of the transparent electrode 7 of the touch panel sensor 1 or the like is broken. Therefore, the shape of the cut surface of the frame edge portion 3 is advantageous for disconnection if it is a straight tapered type. Thus, the frame edge portion 3 is formed into a tapered shape under the photoresist prescription and process conditions.

框緣部3係由吸收可見光且穿透紅外線的顏料系光阻之光硬化物所構成。此處，所謂的顏料系光阻，就是指使顏料分散在溶劑所溶解的樹脂中者，所謂顏料系光阻的光硬化物，就是指藉由對該顏料系光阻進行微影法的曝光處理而使硬化者。 The frame edge portion 3 is composed of a photocured material of a pigment-based photoresist that absorbs visible light and penetrates infrared rays. Here, the term "pigment-based photoresist" refers to a method in which a pigment is dispersed in a resin in which a solvent is dissolved, and a photo-cured material of a pigment-based photoresist means an exposure treatment by lithography of the pigment-based photoresist. And make the hardener.

吸收可見光的程度，一般以光學濃度(Optical Density)之亦稱為OD值之值來表示。測定係依據JIS-K-7605規格，使用Macbeth光學濃度計等來進行，將垂直透過光束照射於試料，以log(對數)表示與沒有試料的狀態之比而得。光學濃度愈高則透過率愈低，透過率100%時光學濃度成為0。 The degree of absorption of visible light is generally expressed as the value of the optical density (Optical Density), also referred to as the OD value. The measurement was carried out in accordance with JIS-K-7605, using a Macbeth optical densitometer or the like, and a vertical transmission beam was irradiated onto the sample, and a ratio of log (logarithm) to a state without a sample was obtained. The higher the optical density, the lower the transmittance, and the optical density becomes zero at a transmittance of 100%.

於本實施形態中，顏料系光阻係含有碳黑及氧化鈦以外的至少2種類以上之顏料的混合物之偽黑光阻。作為例子，可舉出形成彩色濾光片的著色透明層時所用之顏料，藉由至少混合以C.I.顏料紅1、2、3、4、5、6、7、8、9、10、11、12、14、41、48：1、48：2、48：3、48：4、57：1、81、81：1、81：2、81：3、81：4、97、122、123、146、149、166、168、169、176、177、178、179、180、184、185、187、192、200、202、208、210、215、216、217、220、223、224、226、227、228、240、242、246、254、255、264、270、272、273、274，276、277、278、279、280、281、282、283、284、285、286、287等為代表的紅色(RED)系顏料，以C.I.顏料藍15、15：1、15：2、15：3、15：4、15：6、16、22、60、64、80等為代表的藍色(BLUE)系顏料，而模擬地成為黑色者。又，亦可使用呈紅色及紫色的鹼性染料、酸性染料或彼等染料的造鹽化合物。 In the present embodiment, the pigment-based photoresist contains a pseudo black resist of a mixture of at least two types of pigments other than carbon black and titanium oxide. As As an example, a pigment used in forming a colored transparent layer of a color filter may be mentioned by mixing at least CI Pigment Red 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12 , 14, 41, 48:1, 48:2, 48:3, 48:4, 57:1, 81, 81:1, 81:2, 81:3, 81:4, 97, 122, 123, 146 , 149, 166, 168, 169, 176, 177, 178, 179, 180, 184, 185, 187, 192, 200, 202, 208, 210, 215, 216, 217, 220, 223, 224, 226, 227 228, 240, 242, 246, 254, 255, 264, 270, 272, 273, 274, 276, 277, 278, 279, 280, 281, 282, 283, 284, 285, 286, 287, etc. Red (RED) pigment, blue represented by CI Pigment Blue 15, 15:1, 15:2, 15:3, 15:4, 15:6, 16, 22, 60, 64, 80, etc. (BLUE ) is a pigment, and the analog is black. Further, a salt-forming compound which is a red or purple basic dye, an acid dye or a dye thereof may also be used.

又，於本實施形態中，除了紅色系顏料與藍色系顏料，還可更添加黃色(YELLOW)系顏料。已知黃色系顏料係吸收可見光的低波長區域，即波長500nm以下之光(例如，鹽治孜著(昭和40年)「印刷油墨教室」(日本印刷新聞社)P170~173)。藉由在紅色系顏料與藍色系顏料中添加黃色系顏料，黃色系顏料吸收低波長可見光，可更接近黑色。 Further, in the present embodiment, in addition to the red pigment and the blue pigment, a yellow (YELLOW) pigment may be further added. It is known that the yellow pigment is a low-wavelength region that absorbs visible light, that is, a light having a wavelength of 500 nm or less (for example, Salt Printing (Showa 40) "Printing Ink Classroom" (Japan Printing News Agency) P170-173). By adding a yellow pigment to the red pigment and the blue pigment, the yellow pigment absorbs low-wavelength visible light and can be closer to black.

作為黃色(YELLOW)系顏料之例，可舉出C.I.顏料黃1、2、3、4、5、6、10、12、13、14、15、16、17、18、20、24、31、32、34、35、35：1、36、36：1、37、37：1、40、42、43、53、55、60、61、62、63、65、73、74、77、81、83、86、93、94、95、97、98、100、101、 104、106、108、109、110、113、114、115、116、117、118、119、120、123、125、126、127、128、129、137、138、139、144、146、147、148、150、151、152、153、154、155、156、161、162、164、166、167、168、169、170、171、172、173、174、175、176、177、179、180、181、182、185、187、188、193、194、198、199、213、214、218、219、220、221。又，亦可併用呈黃色的鹼性染料、酸性染料或彼等染料的造鹽化合物。 Examples of the yellow (YELLOW) pigment include CI Pigment Yellow 1, 2, 3, 4, 5, 6, 10, 12, 13, 14, 15, 16, 17, 18, 20, 24, 31. 32, 34, 35, 35: 1, 36, 36: 1, 37, 37: 1, 40, 42, 43, 53, 55, 60, 61, 62, 63, 65, 73, 74, 77, 81, 83, 86, 93, 94, 95, 97, 98, 100, 101, 104, 106, 108, 109, 110, 113, 114, 115, 116, 117, 118, 119, 120, 123, 125, 126, 127, 128, 129, 137, 138, 139, 144, 146, 147, 148, 150, 151, 152, 153, 154, 155, 156, 161, 162, 164, 166, 167, 168, 169, 170, 171, 172, 173, 174, 175, 176, 177, 179, 180, 181, 182, 185, 187, 188, 193, 194, 198, 199, 213, 214, 218, 219, 220, 221. Further, a salt-forming compound which is a yellow basic dye, an acid dye or a dye thereof may be used in combination.

於本實施形態的顏料系光阻中，亦可更添加紫色(Violet)系顏料。藉由添加紫色系顏料，與沒有添加時比較下，容易吸收波長550nm附近之光，可成為光學濃度(OD值)更高的黑色。 In the pigment-based resist of the present embodiment, a violet (Violet) pigment may be further added. By adding a purple-based pigment, it is easy to absorb light having a wavelength of around 550 nm, and it is possible to obtain black having a higher optical density (OD value) than when it is not added.

The ratio of the yellow pigment is preferably 5 to 20%. When it is mixed outside this range, the concealability near the wavelength of 550 nm which is most easily visually recognized is lowered, and the optical density (OD value) of the frame edge portion 3 becomes less than 3, and good light-shielding property is not obtained.

混合紅色系顏料、藍色系顏料、黃色系顏料與紫色系顏料時，以全部顏料當作100%時的紅色系顏料之比例較佳為40~60%，藍色系顏料之比例較佳為30~50%，黃色系顏料之比例較佳為5~20%，紫色系顏料之比例較佳為10~30%。於此範圍外混合時，最容易視覺辨認的波長550nm附近之隱蔽性降低，框緣部3的光學濃度(OD值)變成低於3，得不到良好的遮光性。 When the red pigment, the blue pigment, the yellow pigment, and the violet pigment are mixed, the ratio of the red pigment when the total pigment is 100% is preferably 40 to 60%, and the ratio of the blue pigment is preferably 30 to 50%, the proportion of the yellow pigment is preferably 5 to 20%, and the ratio of the purple pigment is preferably 10 to 30%.

The content of the sensitizer may be used in an amount of 1.0 to 100 parts by weight based on 100 parts by weight of the photopolymerization initiator.

<多官能硫醇> <Multifunctional thiol>

多官能硫醇係具有2個以上的硫醇(SH)基之化合物。多官能硫醇係藉由與光聚合引發劑一起使用，而在光照射後的自由基聚合過程中，作為鏈轉移劑作用，由於產生不易遭受氧所致的聚合阻礙之含硫自由基，所得之彩色濾光片用著色組成物變成高感度。特別地，較佳為SH基已鍵結於亞甲基、伸乙基等的脂肪族基之多官能脂肪族硫醇。 A polyfunctional thiol is a compound having two or more thiol (SH) groups. The polyfunctional thiol is used together with a photopolymerization initiator, and in the radical polymerization process after light irradiation, it acts as a chain transfer agent, and generates a sulfur-containing radical which is less likely to be inhibited by polymerization due to oxygen. The color filter becomes highly sensitive with the coloring composition. In particular, a polyfunctional aliphatic thiol having an SH group bonded to an aliphatic group such as a methylene group or an ethyl group is preferred.

例如，可舉出己二硫醇、癸二硫醇、1,4-丁二醇雙硫代丙酸酯、1,4-丁二醇雙巰基乙酸酯、乙二醇雙巰基乙酸酯、乙二醇雙硫代丙酸酯、三羥甲基丙烷三個巰基乙酸酯、三羥甲基丙烷三個硫代丙酸酯、三羥甲乙烷三個(3-巰基丁酸酯)、三羥甲基丙烷三個(3-巰基丁酸酯)、三羥甲基丙烷三個(3-巰基丙酸酯)、季戊四醇四個巰基乙酸酯、季戊四醇四個硫代丙酸酯、季戊四醇四個(3-巰基丙酸酯)、二季戊四醇六個(3-巰基丙酸酯)、三巰基丙酸三個(2-羥基乙基)異三聚氰酸酯、1,4-二甲基巰基苯、2,4,6-三巰基-s-三、2-(N,N-二丁基胺基)-4,6-二巰基-s- 三等。此等多官能硫醇係可單獨1種或混合2種以上使用。 For example, hexanedithiol, decanedithiol, 1,4-butanediol dithiopropionate, 1,4-butanediol bis-mercaptoacetate, ethylene glycol bis-mercaptoacetate , ethylene glycol dithiopropionate, trimethylolpropane three thioglycolate, trimethylolpropane three thiopropionate, trimethylolethane three (3-mercaptobutyrate , trimethylolpropane three (3-mercaptobutyrate), trimethylolpropane three (3-mercaptopropionate), pentaerythritol four thioglycolate, pentaerythritol four thiopropionate , pentaerythritol four (3-mercaptopropionate), dipentaerythritol six (3-mercaptopropionate), tris-propyl propionic acid three (2-hydroxyethyl) isocyanate, 1,4- Dimethyl nonylbenzene, 2,4,6-trimethyl-s-three , 2-(N,N-dibutylamino)-4,6-dimercapto-s- Wait. These polyfunctional thiols may be used alone or in combination of two or more.

相對於100重量份的著色劑而言，多官能硫醇之含量較佳為0.05~100重量份，更佳為1.0~50.0重量份。藉由使用0.05重量份以上的多官能硫醇，可得到更良好的耐顯像性。使用硫醇(SH)基為1個的單官能硫醇時，得不到如此的耐顯像性之提高。 The content of the polyfunctional thiol is preferably from 0.05 to 100 parts by weight, more preferably from 1.0 to 50.0 parts by weight, per 100 parts by weight of the color former. More excellent development resistance can be obtained by using 0.05 part by weight or more of the polyfunctional thiol. When a monofunctional thiol having one thiol (SH) group is used, such improvement in development resistance cannot be obtained.

<紫外線吸收劑、聚合抑制劑> <Ultraviolet absorber, polymerization inhibitor>

本實施形態的顏料系光阻，係藉由含有紫外線吸收劑或聚合抑制劑，而可控制畫線部的圖案形狀與解像性。作為紫外線吸收劑，例如可舉出2-[4-[(2-羥基-3-(十二基及十三基)氧基丙基)氧基]-2-羥基苯基]-4,6-雙(2,4-二甲基苯基)-1,3,5-三、2-(2-羥基-4-[1-辛基氧基羰基乙氧基]苯基)-4,6-雙(4-苯基苯基)-1,3,5-三等之羥基苯基三系、2-(5-甲基-2-羥基苯基)苯并***、2-(2H-苯并***-2-基)-4,6-雙(1-甲基-1-苯基乙基)苯酚、2-(3-第三丁基-5-甲基-2-羥基苯基)-5-氯苯并***等之苯并***系、2,4-二羥基二苯基酮、2-羥基-4-辛氧基二苯基酮、2,2’,4,4’-四羥基二苯基酮等之二苯基酮系、水楊酸苯酯、水楊酸對第三丁基苯酯等之水楊酸酯系、乙基-2-氰基-3,3’-二苯基丙烯酸酯等之氰基丙烯酸酯系、2,2,6,6，-四甲基哌啶-1-氧基(三丙酮-胺-N-氧基)、雙(2,2,6,6-四甲基-4-哌啶基)-癸二酸酯、聚[[6-[(1,1,3,3-四丁基)胺基]-1,3,5-三-2,4-二基][(2,2,6,6-四甲基-4-哌啶基)亞胺基]等之受阻胺系等，可單獨或混合2種以上的此等來使用。 The pigment-based photoresist of the present embodiment can control the pattern shape and resolution of the line drawing portion by containing an ultraviolet absorber or a polymerization inhibitor.

又，作為聚合抑制劑(I)，例如可舉出甲基氫醌、第三丁基氫醌、2,5-二-第三丁基氫醌、4-苯醌、4-甲氧基苯酚、4-甲氧基-1-萘酚、第三丁基兒茶酚等之氫醌衍生物及苯酚化合物、啡噻、雙-(1-二甲基苄基)啡噻、3,7-二辛基啡噻等之胺化合物、二丁基二硫胺甲酸銅、二乙基二硫胺甲酸銅、二乙基二硫胺甲酸錳、二苯基二硫胺甲酸錳等之銅及錳鹽化合物、4-亞硝基苯酚、N-亞硝基二苯基胺、N-亞硝基環己基羥基胺、N-亞硝基苯基羥基胺等之亞硝基化合物及其銨鹽或鋁鹽等，可單獨或混合2種以上的此等來使用。 Further, examples of the polymerization inhibitor (I) include methylhydroquinone, tert-butylhydroquinone, 2,5-di-tert-butylhydroquinone, 4-benzoquinone, and 4-methoxyphenol. , hydroquinone derivatives such as 4-methoxy-1-naphthol and tert-butylcatechol, and phenol compounds, thiophene Bis-(1-dimethylbenzyl) phenoxy 3,7-dioctylmorphothiophene Copper and manganese salt compounds such as amine compounds, copper dibutyldithiocarbamate, copper diethyldithiocarbamate, manganese diethyldithiocarbamate, manganese diphenyldithiocarbamate, etc. 4- a nitroso compound such as nitrosophenol, N-nitrosodiphenylamine, N-nitrosocyclohexylhydroxylamine or N-nitrosophenylhydroxylamine, and an ammonium salt or an aluminum salt thereof, These may be used alone or in combination of two or more.

More excellent resolution can be obtained by using 0.01 part by weight or more of the ultraviolet absorber or the polymerization inhibitor.

關於由顏料系光阻的光硬化物所構成之框緣部3，為了充分遮蔽所入射的可見光，框緣部3的光學濃度(OD值)較佳為3以上。又，於波長400nm~750nm的可見光之範圍中，透過率較佳為20%以下，更佳為10%以下。又，為了使紅外線穿透而進行紅外線通信，框緣部3在波長850nm~1000nm之範圍中的平均透光率較佳為80%以上。 In the frame edge portion 3 composed of the photocured material of the pigment-based photoresist, the optical density (OD value) of the frame edge portion 3 is preferably 3 or more in order to sufficiently shield the incident visible light. Further, in the range of visible light having a wavelength of 400 nm to 750 nm, the transmittance is preferably 20% or less, more preferably 10% or less. Moreover, in order to transmit infrared rays and perform infrared communication, the average light transmittance of the frame edge portion 3 in the range of 850 nm to 1000 nm is preferably 80% or more.

又，顏料系光阻的光硬化物之比介電常數較佳必須為10以下，更佳為5.0以下。此係為了確保靜電容量結合方式的觸控面板之響應性。另外，比介電常數若為4.0以下，則可抑制顏料系光阻的靜電容量之形成。 Further, the specific dielectric constant of the photocured material of the pigment-based photoresist is preferably 10 or less, more preferably 5.0 or less. This is to ensure the responsiveness of the touch panel of the electrostatic capacity combination method. Further, when the specific dielectric constant is 4.0 or less, the formation of the electrostatic capacity of the pigment-based photoresist can be suppressed.

此處所謂的比介電常數，係以介質的介電常數ε與真空的介電常數ε₀之比ε/ε₀來表示，不論所用的單位系統為何，為取一定值的無次元量。亦有將比介電常數僅稱為介電常數，與比介電常數無區別地表現之情況，但本發明之特徵係只有意味比介電常數，不因此等的表現之差異而被限定。 Here, the specific dielectric constant is expressed by the ratio ε/ε ₀ of the dielectric constant ε of the medium to the dielectric constant ε ₀ of the vacuum, and is a non-dimensional quantity of a constant value regardless of the unit system used. There is also a case where the specific dielectric constant is simply referred to as a dielectric constant and is expressed differently from the specific dielectric constant. However, the features of the present invention are limited only by the difference between the dielectric constant and the performance.

比介電常數之測定係依照JIS-K-6911、JIS-C-6481、ASTM-D-150中的任一規格來製作試驗片，使用阻抗分析器(LCR計)進行，另外亦可對在鋁蒸鍍電極上，將顏料系光阻成膜為指定的厚度，再於其上蒸鍍鋁電極而製作的試驗片，用阻抗分析器來計測而進行。 The specific dielectric constant is measured in accordance with any of JIS-K-6911, JIS-C-6481, and ASTM-D-150, and is performed using an impedance analyzer (LCR meter). On the aluminum vapor-deposited electrode, a pigment-based photoresist was formed into a film having a predetermined thickness, and a test piece prepared by vapor-depositing an aluminum electrode thereon was measured by an impedance analyzer.

又，於本實施形態的框緣部3上，為了形成金屬配線6及透明電極7、8，必須確保電絕緣性。即，顏料系光阻的體積電阻率，即使為以往的1×10⁸Ω‧cm也不充分，較佳為1×10⁹Ω‧cm以上，更佳為1×10¹²Ω‧cm以上。當顏料系光阻的光硬化物之體積電阻率低於1×10⁹Ω‧cm時，在由顏料系光阻的光硬化物所成之框緣上所形成之金屬配線及透明電極配線變短路(short)，觸控面板感測器變無法正常動作。 Further, in the frame edge portion 3 of the present embodiment, in order to form the metal wiring 6 and the transparent electrodes 7 and 8, it is necessary to ensure electrical insulation. In other words, the volume resistivity of the pigment-based photoresist is not sufficient even in the conventional 1 × 10 ⁸ Ω ‧ cm, and is preferably 1 × 10 ⁹ Ω ‧ cm or more, and more preferably 1 × 10 ¹² Ω ‧ cm or more. When the volume resistivity of the photocured material of the pigment-based photoresist is less than 1 × 10 ⁹ Ω ‧ cm, the metal wiring and the transparent electrode wiring formed on the frame edge formed by the photo-cured material of the pigment-based photoresist become Short circuit, the touch panel sensor does not work properly.

此處所謂的體積電阻率，就是每單位體積的電阻，為藉由測定以各邊1cm之立方體的相對2表面作為電極的2個電極間之電阻而得之在物質所固有的絕對值。亦有將體積電阻率僅稱為電阻率，與體積電阻率無區別地表現之情況，但本發明之特徵係只有意味體積電阻率，不因此等的表現之差異而被限定。 The volume resistivity referred to herein is the electric resistance per unit volume, and is an absolute value inherent to a substance obtained by measuring the electric resistance between two electrodes of an electrode having a surface of 1 cm on each side as an electrode. There is also a case where the volume resistivity is simply referred to as resistivity and is expressed indistinguishable from the volume resistivity. However, the features of the present invention are only limited to the volume resistivity, and are not limited by the difference in performance.

體積電阻率之測定係使用依照JIS-K-6911、JIS-K-6271、ASTM-D-257、IEC-60093中的任一規格來製作試驗片，在圓形電極之間藉由絕緣電阻計來測定電阻之方法(雙環電極法)，或在依照JIS-K-7194規格所製作的試驗片上，將4支的針狀電極放置在直線上，使恒定電流流過外側的二探針間，測定在內側的二探針間所發生的電位差，求得電阻(四深針法)之方法來進行。雙環電極法係適合10⁸~10¹⁶Ω的絕緣體之電阻率測定，為將500V施加於電極間，測定1分鐘後的電阻值，自電極形狀求得體積電阻率及表面電阻率之方法。另一方面，四深針法係適合10^-2~10⁷Ω的導電體之電阻率測定，將所測定的電阻乘以試料厚度、校正係數RCF(Resistivity Correction Factor)而算出體積電阻率。此等係按照所測定的體積電阻率之範圍來適宜地區分使用。 The volume resistivity was measured by using any one of JIS-K-6911, JIS-K-6271, ASTM-D-257, and IEC-60093 to prepare a test piece, and an insulating resistance meter was used between the circular electrodes. To measure the electric resistance (double-ring electrode method), or to place four needle electrodes on a straight line on a test piece prepared in accordance with JIS-K-7194, and to make a constant current flow between the outer two probes. The potential difference generated between the two inner probes was measured and the resistance (four-deep needle method) was determined. The double-ring electrode method is suitable for measuring the resistivity of an insulator of 10 ⁸ to 10 ¹⁶ Ω, and is a method of measuring the resistance value after 1 minute by applying 500 V between the electrodes, and determining the volume resistivity and the surface resistivity from the electrode shape. On the other hand, the four-deep stitch method is suitable for measuring the resistivity of a conductor of 10 ^-2 to 10 ⁷ Ω, and multiplying the measured resistance by the thickness of the sample and the correction coefficient RCF (Resistivity Correction Factor) to calculate the volume resistivity. These are suitably used according to the range of volume resistivity measured.

透明電極7係為了檢測出X座標。透明電極7係使用具有導電性與透明性之材料，形成在顯示區域10內的蓋玻璃2上。透明電極7係在X方向及Y方向中間歇且排列成行列狀，電連接於與X方向鄰接的跨接配線4。透明電極7例如係由ITO(銦錫氧化物)所形成。 The transparent electrode 7 is for detecting the X coordinate. The transparent electrode 7 is formed on the cover glass 2 in the display region 10 by using a material having conductivity and transparency. The transparent electrode 7 is intermittently arranged in a matrix in the X direction and the Y direction, and is electrically connected to the jumper wiring 4 adjacent to the X direction. The transparent electrode 7 is formed, for example, of ITO (Indium Tin Oxide).

透明電極8係為了檢測出Y座標。於本實施形態中，透明電極8係使用與透明電極7相同的材料，藉由與透明電極7相同的步驟來形成。透明電極8係將在Y方向所排列的透明電極7之各列間於Y方向中延伸，如第3圖及第4圖所示，於第1絕緣膜5上與跨接配線4立體交叉。 The transparent electrode 8 is for detecting the Y coordinate. In the present embodiment, the transparent electrode 8 is formed of the same material as the transparent electrode 7 by the same steps as the transparent electrode 7. The transparent electrode 8 extends in the Y direction between the respective rows of the transparent electrodes 7 arranged in the Y direction, and intersects the jumper wiring 4 on the first insulating film 5 as shown in FIGS. 3 and 4 .

絕緣保護膜9係以覆蓋跨接配線4、金屬配線6、透明電極7及8、框緣部3之方式，除了相當於金屬配線6的拉出配線之部分以外，形成在蓋玻璃2的幾乎全面上。絕緣保護膜9係具有作為保護蓋玻璃2上所形成的各構成要素之保護膜的機能。 The insulating protective film 9 covers the jumper wiring 4, the metal wiring 6, the transparent electrodes 7 and 8, and the frame edge portion 3, and is formed on the cover glass 2 except for the portion corresponding to the drawn wiring of the metal wiring 6. Comprehensively. The insulating protective film 9 has a function as a protective film for protecting each constituent element formed on the cover glass 2.

再者，於本實施形態的觸控面板感測器1中，跨接配線4、絕緣膜5、透明電極7及8、絕緣保護膜9係相當於感測器層。 Further, in the touch panel sensor 1 of the present embodiment, the jumper wiring 4, the insulating film 5, the transparent electrodes 7 and 8, and the insulating protective film 9 correspond to a sensor layer.

第7圖中顯示在本實施形態的觸控面板感測器1上，直接貼附作為顯示裝置的液晶面板21而成為一體時之形態。如第7圖所示，液晶面板21具備偏光板22及27、前面玻璃23、彩色濾光片24、液晶/電極/TFT等之層25及背面玻璃26。 In the touch panel sensor 1 of the present embodiment, the liquid crystal panel 21 as a display device is directly attached to the touch panel sensor 1 to be integrated. As shown in FIG. 7, the liquid crystal panel 21 is provided with polarizing plates 22 and 27, and front side. The glass 23, the color filter 24, the layer 25 of the liquid crystal/electrode/TFT, and the back glass 26.

液晶面板21係藉由未圖示的背光，自背面玻璃26側來照明。液晶面板21所顯示的圖像，係透過蓋玻璃2上所形成的框緣部3之內側的顯示區域10而被視覺辨認，藉由觸控面板感測器1來操作。又，與液晶面板21相比，觸控面板感測器1係僅具有框緣部3的部分變成大的寬度。 The liquid crystal panel 21 is illuminated from the back glass 26 side by a backlight (not shown). The image displayed on the liquid crystal panel 21 is visually recognized by the display region 10 on the inner side of the frame edge portion 3 formed on the cover glass 2, and is operated by the touch panel sensor 1. Further, compared with the liquid crystal panel 21, the touch panel sensor 1 has only a portion having the frame edge portion 3 having a large width.

於本實施形態中，如上述，由於框緣部3係以吸收可見光且穿透紅外線的紅外線遮光材料來構成，故與在框緣部設置紅外線通信用窗且形成紅外線透過膜的情況比較下，可簡化前面板的蓋玻璃2之製造步驟，而且可減薄。再者，由於可以不將紅外線通信用窗設置在框緣部3的特定位置，故可以將紅外線通信部設置在框緣部3的下方之任意位置。 In the present embodiment, the frame edge portion 3 is configured by an infrared light shielding material that absorbs visible light and penetrates infrared rays. Therefore, compared with the case where an infrared communication window is provided at the frame edge portion and an infrared ray transmitting film is formed, The manufacturing steps of the cover glass 2 of the front panel can be simplified, and the thickness can be reduced. Further, since the infrared communication window can be not provided at a specific position of the frame edge portion 3, the infrared communication portion can be provided at any position below the frame edge portion 3.

又，本實施形態所用的顏料系光阻之光硬化物，與以往的彩色濾光片用之黑光阻材料的光硬化物相比，由於比介電常數低，而且體積電阻率高，故框緣部3的絕緣變成不需要，可在框緣部3上直接形成感測器層或金屬配線6。另外，由於覆蓋框緣部3的絕緣膜係不需要，而減少步驟數，故可實現成本降低及良率上升。 Further, the photocured material of the pigment-based photoresist used in the present embodiment has a lower specific dielectric constant and a higher volume resistivity than the photocured material of the conventional black photoresist material for a color filter. The insulation of the edge portion 3 becomes unnecessary, and the sensor layer or the metal wiring 6 can be directly formed on the frame edge portion 3. Further, since the insulating film covering the frame edge portion 3 is not required, the number of steps is reduced, so that cost reduction and yield increase can be achieved.

另外，於本實施形態中，對框緣部3的材料進行微影法的曝光處理。藉由網版印刷形成框緣部3時，雖然框緣部3的表面凹凸變粗，但若藉由微影法形成框緣部3，則框緣部3的表面變平滑。因此，可在框緣部3上直接、安定地形成金屬配線6。 Further, in the present embodiment, the material of the frame edge portion 3 is subjected to exposure processing by the lithography method. When the frame edge portion 3 is formed by screen printing, the surface irregularities of the frame edge portion 3 become thicker. However, when the frame edge portion 3 is formed by the lithography method, the surface of the frame edge portion 3 becomes smooth. Therefore, the metal wiring 6 can be formed directly and stably on the frame edge portion 3.

此處，如以往的技術，在框緣部3設置紅外線通信用窗時，必須在框緣部3上形成紅外線透過膜，若形成紅外線透過膜，則對於框緣部3的表面而言，發生階差。而且，於此階差上若設置金屬配線6，則有容易斷線的不良狀況。然而，於本實施形態時，由於在框緣部3不發生紅外線透過膜所致的階差，故可將金屬配線6形成在框緣部3的任意位置。 Here, as in the prior art, when the infrared communication window is provided in the frame edge portion 3, it is necessary to form an infrared ray permeable film on the frame edge portion 3. When the infrared ray permeable film is formed, the surface of the frame edge portion 3 occurs. Step difference. Further, if the metal wiring 6 is provided for this step, there is a problem that the wire is easily broken. However, in the present embodiment, since the step caused by the infrared ray transmitting film does not occur in the frame edge portion 3, the metal wiring 6 can be formed at any position of the frame edge portion 3.

However, the second insulating layer is formed in the frame portion 3. After 11th, the arrangement of the metal wiring 6 is different.

於第1實施形態中，構成框緣部3的材料之體積電阻率大，比介電常數低，而且藉由對框緣部3的材料進行微影法的曝光處理以使硬化，使表面成為平滑，在框緣部3上直接形成金屬配線6。此處，當欲更確實地確保絕緣性時，或藉由網版印刷形成框緣部3而表面的凹凸為粗時，如第8圖所示，較佳為在框緣部3上形成第2絕緣層11，由其來設置金屬配線6。 In the first embodiment, the material constituting the frame edge portion 3 has a large volume resistivity and a low specific dielectric constant, and is subjected to a lithography exposure treatment to harden the material of the frame edge portion 3 to make the surface Smoothly, the metal wiring 6 is directly formed on the frame edge portion 3.

於本實施形態中，如上述，關於框緣部3，由於以吸收可見光且穿透紅外線的紅外線透過材料來構成，故與在框緣部上設置紅外線通信用窗且形成紅外線透過膜的情況比較下，可簡化前面板的蓋玻璃2之製造步驟，而且可減薄。再者，由於可以不將紅外線通信用窗設置在框緣部3的特定位置，故可以將紅外線通信部設置在框緣部3的下方之任意位置。 In the present embodiment, the frame edge portion 3 is configured by an infrared ray transmissive material that absorbs visible light and penetrates infrared rays. Therefore, compared with the case where an infrared communication window is provided on the frame edge portion and an infrared ray permeable film is formed. In the following, the manufacturing steps of the cover glass 2 of the front panel can be simplified, and the thickness can be reduced. Further, since the infrared communication window can be not provided at a specific position of the frame edge portion 3, the infrared communication portion can be provided at any position below the frame edge portion 3.

又，如本實施形態，為在框緣部上設置金屬配線之構成時，由於在框緣部3不發生紅外線透過膜所致的階差，故可將金屬配線形成在框緣部3的任意位置。 Further, in the present embodiment, when the metal wiring is provided in the frame portion, the step of the infrared ray permeable film does not occur in the frame portion 3, so that the metal wiring can be formed in the frame portion 3. position.
