110a、110b。 此外，反射防止層ll〇a、ll〇b係例如以由折射率為 低、高、低的順序之相異的三層所構成者，並且在由此種 三層所構成的情形係藉由進行三次的浸潰成形法以分別成 形反射防止層110a、110b。另外對各層的成形係施加有熱 硬化處理。 接著，如第10圖（a)所示’在兩面的反射防止層11 〇a、 110b之上以浸潰成形法形成撥水層112a、112b後，如第 10圖（b)所示，將一方之面的撥水層112b予以去除。 再者如第10圖（c)所示，在去除一侧的撥水層112b所 露出的一方表面之反射防止層110b之上以網版印刷法形 成印刷層114，藉此完成大尺寸面板200。 接著如第11圖（a)所示’將該大尺寸面板200切削加 工為各顯示窗板100的大小，藉此可獲得如第11圖（b)所 示的複數個顯示窗板100。此外’就習知技術而言使用的

體，且光學特性（預定的波長帶之光線透過率及光線反射率） 4 322776 201213135 為相同。 近年，尤其在電子機器的顯示窗板100中，係追求更 上一層的反射防止效果，反射防止層110a、110b的兩層同 樣為相同的光學特性，換言之當僅為一種的光學特性時， 就反射防止效果而言要滿足所要求的規格（specification) 係非常地困難，因此最適當的厚度及材質等的選定需要龐 大的時間，而根據情形有使產品開發延遲的疑慮。 再者，在上文所述的習知之製造方法中，由於維持在 能取得多個顯示窗板100的大尺寸基板106的狀態下進行 製造步驟，且對該大尺寸基板106在複數個步驟進行浸潰 成形，故有使得製造裝置大型化而製造成本增加者。 本發明之目的係鑑於上述現狀，而提供一種顯示窗板 及顯示窗板之製造方法，係可輕易地獲得所想要的反射防 止效果，並且可減低製造成本。

月&以貼設於兩表面的反射防止薄片之光學特性為相異的方 式來構成。再者，由於製作為貼設於一方表面之第一反射 防止薄片的光學特性、與貼設於另一方表面的第二反射防 止薄片之光學特性相異，藉此可輕易地獲得期望的反射防 止效果。 另外’依據本發明之顯示窗板之製造方法，能以較少 的步驟獲得顯示窗板，另外由於不進行如習知的浸潰成 形，故可小型化製造裝置並可降低製造成本。 再者，依據本發明之顯示窗板製造方法’由於在貼設 反射防止薄片之前對基板施加表面處理，故即使在透過黏 貼材料將反射防止薄片貼設於基板，且在之後施加熱處理 等的情形也不損壞反射防止薄片的外觀。 另外，由於在形成印刷層之前對反射防止薄片施加表 14 322776 201213135 面處理，故可獲得與印刷層的充分的密合性，並可於反射 . 防止薄片的表面上良好地形成印刷層。 【實施方式】 以下，根據圖式更詳細地說明本發明之實施形態（實施 例）。 本發明係例如在合成樹脂製的基板之一方側與另一方 側施加反射防止處理而成的電子機器之顯示窗板及顯示窗 板之製造方法。 <顯示窗板1〇> 如第1圖所示，本發明之顯示窗板10係將具有高透明 性的板狀之基板12當作基材，並透過黏著材料16a於該基 板12的一方表面貼設有第一反射防止薄片18a，並透過黏 著材料16b於基板12的另一方表面貼設有第二反射防止薄 片 18b。 另外，在貼設於另一方表面的第二反射防止薄片18b 的表面上係部分地形成有印刷層20。 於此，就基板12的材質而言，係可使用具有高透明性 的合成樹脂，例如使用聚碳酸醋（polycarbonate，PC)、聚 曱基丙稀酸酯（polymethylmethacrylate，PMMA)或環婦烴 聚合物（Cyclo Olefin Polymer，COP)為宜。 此外，關於具有高透明性的合成樹脂之選定，雖只要 是配合做為產品所要求的規格做適當選擇者即可，然只要 是以使用日立高科技股份有限公司製的分光光度計U-3010 的1mm厚度的基板測定（波長帶400mm至800mm)下光線透 15 322776 201213135 過率為80%以上者，在維持良好的視覺辨認性上亦適宜β 另外，貼設於基板12的一方表面與另一方表面的第一 反射防止薄片18a、第二反射防止薄片l8b較佳係配合做 為產品所要求的規格適當地從市售品中選擇而使用’例如 亦可使用使反射防止層（未圖示）、硬塗覆（hard coating) 層（未圖示）、與基材層（未圖示）層疊，並於一方的面具有 黏著材料的日油股份有限公司製之AR薄片、曰本化藥股伤 有限公司製之AR薄片等。 此種顯示窗板10較佳係以貼設於該基板12的一方表 面之第-反射防止薄片18a的光學特性、以及貼設於該基 板12的另-方表面之第二反射防土薄片18_光學特性為 相異的方式來設定。 依據此種構成，若將基板d方表面與另一方表面 之兩者的光學特性加以改變，#這兩種光學特性加以組 合，則能以將記載於顯示於第2圖（a)的預疋之波長帶之光 線透過率的圖表的習知之-條光線透過率的曲線（A) ’以貼 設於本發明之顯示窗板10的〆方表面之帛&射防止薄 片18a之光線透過率的曲線（B)，以及貝占°又於$方表面之 第二反射防止薄片18b之光線透過率的曲線(C)的組合來 另外，關於記載於第2圖⑻所禾的預定之波長帶之光 線透過率的圖表的習知之-條光線反射率的曲線⑷也忐 以貼設於本發明之顯示窗板10方表面之帛反射防 止薄片18a的光線反射率的曲線（b)、與貼"又於$方表面 322776 201213135 之第二反射防止薄片18b的光線反射率的曲線（c)的組合 來表現。 因此，能較習知技術更容易地獲得希望的反射防止效 果。 另外，貼設於基板12的一方表面之第一反射防止薄片 18a、與貼設於該基板12的另一方表面之第二反射防止薄 片18b，較佳係將反射防止層（未圖示）、硬塗覆層（未圖 示）、及基材層（未圖示）予以層疊者。 若以這樣的方式構成，則除了反射防止功能之外，也 可增加耐擦傷性與耐衝擊性，故尤其是數位相機與行動電 話等，即使是在直接接觸到顯示窗板10、或者在容易與其 他物品碰撞的環境下使用，也可保護顯示窗板10不受損壞 或損傷。 再者若使第一反射防止薄片18a、第二反射防止薄片 18b具有撥水性，則即使在例如水滴飛散時也可以輕易擦 去，並儘快使視覺辨認性恢復。 第一反射防止薄片18a、第二反射防止薄片18b的撥 水處理，係只要是使撥水材料混合至反射防止層，或者將 撥水材料加以稀釋的溶液以從以往為人所知的方法進行塗 布處理即可。 另外，就第一反射防止薄片18a、第二反射防止薄片 18b而言，亦可選定具有高撥水性的反射防止薄片，例如 反射防止層的最上層係以氟素系之有機薄膜等具有高撥水 性之薄膜所形成的反射防止層之反射防止薄片。 17 322776 201213135 此外，將第一反射防止薄片18a、第二反射防止薄片 18b貼設於基板12之黏著材料16a、16b的厚度，較佳係 設定為第一反射防止薄片18a為在5/im至20/zm的範圍 内，此時第一反射防止薄片18a的鉛筆硬度係為3H至2H。 另外，設定為第二反射防止薄片18b的厚度為在5/zm至 50ym的範圍内為宜，此時第二反射防止薄片18a的鉛筆 硬度係為3H至HB。鉛筆硬度係黏著材料的厚度越薄，越 會從HB朝3H增加硬度。 若以如此方式設定，則第一反射防止薄片18a與第二 反射防止薄片18b係穩定地貼設於基板12,並且可提升第 一反射防止薄片18a的耐擦傷性故為較佳。 如此本發明之顯示窗板10係為在具有高透明性的板 狀基板12的一方表面透過黏著材料16a貼設有第一反射防 止薄片18a，並在該基板12的另一方表面透過黏著材料16b 貼設有第二反射防止薄片18b，兩面可分別獲得反射防止 效果的構造及層，故透過組合兩種光學特性，能較習知技 術更容易地獲得希望的反射防止效果。 <顯示窗板1〇之製造方法> 接著說明關於上述的顯示窗板10之製造方法。 首先，如第3圖（a)所示，為了以射出成形獲得帶有突 片32之板狀的基板（帶有突片的基板30)，故準備有於内 部具有帶有突片的基板成形用空間、由上模具22及下模具 24所構成之模具26。 接著在此狀態下關閉模具26，並如第3圖（b)所示， 18 322776 201213135 藉由將熔融的具有高透明性的合成樹脂（例如聚碳酸酿 (PC)、聚曱基丙烯酸酯（PMMA)或環烯烴聚合物）射出於模臭 26内，藉以獲得具有高透明性的板狀帶有突片的基板3〇 ^ 此外，所成形的帶有突片的基板30係具有如第6圖戶斤 示的形狀，而於基板12之相對的兩側端分別形成有突片 32、32者。該突片32、32係在之後的製造步驟中當作同 持突片32、32並使步驟進行所使用的處所，是在使製造迅 速化上非常重要的部分。 突片32的兩端侧之厚度方向的位置與突片32的尺十 係依據製造裝置之操作形態上最佳的位置及尺寸來決定 者。另外，在射出成形所使用的模具26中，係不論為以一 次射出（shot)能成形一個帶有突片的基板3〇的單個取得 形式’或者是在一次獲得複數個的複數取得形式皆可。 接著，如第4圖（a)所示，利用此種射出成形所獲得之 帶有突片的基板30，分別於其一方表面透過黏著材料16a 貼設有第一反射防止薄片18a’而於另一方表面透過黏著 材料16b貼設有第二反射防止薄片18b。對帶有突片的基 板30之反射防止薄片的貼設’係使黏著材料朝向帶有突片 的基板30的表面側，並將反射防止薄片載置於帶有突片的 基板30之上，並藉由橡膠滾筒等推壓反射防止薄片的表面 來進行。 另外，較佳係在貼設該第一反射防止薄片18a、第二 反射防止薄片18b之前，以後文所述的表面處理方法來處 理帶有突片的基板30的一方表面及/或另一方表面，以預 322776 19 201213135 先促進反射防止薄片的貼設性。 此外，在表面處理後貼設於帶有突片的基板30之第 一反射防止薄片18a、第二反射防止薄片igb，較佳係設定 為較基板12更大的尺寸。這是因為即使在對帶有突片的基 板30貼設第一反射防止薄片18a、第二反射防止薄片18b 時稍微產生偏離’也可在基板12的全部表面貼設反射防止 薄片。另外，第一反射防止薄片18a、第二反射防止薄片 18b係為了減低工時而成捲筒（r〇ii)狀，並以較基板12更 大的尺寸來供給。 在於帶有突片的基板30的一方表面貼設了第一反射 防止薄片18a之後，係如第4圖（b)所示，配合基板的形狀 利用雷射切割第一反射防止薄片18a。另外，同樣地，如 第4圖（c)所示，在於帶有突片的基板3〇的另一方表面貼 設了第二反射防止薄片18b之後，係如第4圖（d)所示配合 基板的形狀利用雷射切割第二反射防止薄片18b。使用的 雷射係亦可使用紫外波長之短波長雷射或綠色雷射（green laser) ’然當考慮成本效益（cost performance)時則使用 一氧化碳雷射（C〇2 laser)為宜。 在切割該第一反射防止薄片18a、第二反射防止薄片

AR sheet made by the company. The display window panel 10 preferably has optical characteristics of the first anti-reflection sheet 18a attached to one surface of the substrate 12, and a second reflective anti-soil sheet 18 attached to the other surface of the substrate 12. _ Optical characteristics are set in a different way. According to such a configuration, when the optical characteristics of both the surface of the substrate d and the other surface are changed, and the two optical characteristics of # are combined, it can be described in the preview shown in Fig. 2(a). The conventional light-transmission rate curve (A) of the wavelength band of the wavelength band is used to illuminate the light transmittance of the film 18a attached to the square surface of the display panel 10 of the present invention. The curve (B), and the combination of the curve (C) of the light transmittance of the second reflection preventing sheet 18b on the square surface, in addition to the predetermined wavelength band described in Fig. 2 (8) The curve (4) of the light transmittance of the chart of the light transmittance is also a curve (b) of the light reflectance of the 帛 reflection preventing sheet 18a attached to the surface of the display window 10 of the present invention, and the paste " is also expressed in a combination of the curve (c) of the light reflectance of the second reflection preventing sheet 18b of the square surface 322776 201213135. Therefore, the desired reflection preventing effect can be obtained more easily than the conventional technique. Further, the first reflection preventing sheet 18a attached to one surface of the substrate 12 and the second reflection preventing sheet 18b attached to the other surface of the substrate 12 are preferably an antireflection layer (not shown), A hard coat layer (not shown) and a base material layer (not shown) are laminated. If it is configured in such a manner, in addition to the reflection preventing function, scratch resistance and impact resistance can be increased, so that especially a digital camera and a mobile phone, even if it is in direct contact with the display window 10, or is easy It can also protect the display window 10 from damage or damage when used in an environment where it collides with other items. Further, when the first reflection preventing sheet 18a and the second reflection preventing sheet 18b are made water-repellent, they can be easily wiped off even when water droplets are scattered, for example, and the visibility can be restored as soon as possible. The water repellent treatment of the first reflection preventing sheet 18a and the second reflection preventing sheet 18b is carried out by a method known in the art as long as the water repellent material is mixed with the antireflection layer or the water repellent material is diluted. The coating treatment is sufficient. Further, in the first reflection preventing sheet 18a and the second reflection preventing sheet 18b, an antireflection sheet having high water repellency may be selected. For example, the uppermost layer of the antireflection layer is made of a fluorine-based organic film or the like. The reflection preventing layer formed by the aqueous film forms a sheet for preventing reflection. 17 322776 201213135 Further, the thickness of the adhesive material 16a, 16b to which the first reflection preventing sheet 18a and the second reflection preventing sheet 18b are attached to the substrate 12 is preferably set so that the first reflection preventing sheet 18a is at 5/im to In the range of 20/zm, the pencil hardness of the first reflection preventing sheet 18a is 3H to 2H. Further, it is preferable that the thickness of the second reflection preventing sheet 18b is in the range of 5/zm to 50ym, and the pencil hardness of the second reflection preventing sheet 18a is 3H to HB. The pencil hardness is the thinner the thickness of the adhesive material, and the hardness is increased from HB to 3H. By setting in this manner, the first reflection preventing sheet 18a and the second reflection preventing sheet 18b are stably attached to the substrate 12, and the scratch resistance of the first reflection preventing sheet 18a can be improved, which is preferable. In the display panel 10 of the present invention, the first reflection preventing sheet 18a is attached to one surface of the plate-like substrate 12 having high transparency through the adhesive material 16a, and the adhesive material 16b is transmitted through the other surface of the substrate 12. The second reflection preventing sheet 18b is attached, and the structure and the layer for preventing the reflection effect can be obtained on both sides. Therefore, by combining the two kinds of optical characteristics, the desired reflection preventing effect can be more easily obtained than the conventional technique. <Manufacturing Method of Display Window Panel 1> Next, a method of manufacturing the display panel 10 described above will be described. First, as shown in Fig. 3(a), in order to obtain a plate-like substrate (the substrate 30 with a tab) having the tabs 32 by injection molding, it is prepared to have a substrate having a tab formed therein. A space 26 is used to form a mold 26 composed of an upper mold 22 and a lower mold 24. Next, the mold 26 is closed in this state, and as shown in Fig. 3(b), 18 322776 201213135 by melting a synthetic resin having high transparency (for example, polycarbonate (PC), polydecyl acrylate ( PMMA) or a cyclic olefin polymer) is injected into the mold odor 26 to obtain a plate-like tab-shaped substrate having high transparency. Further, the formed substrate 30 with a tab has the sixth The shape of the figure is shown in the figure, and the tabs 32 and 32 are respectively formed on the opposite side ends of the substrate 12. The tabs 32, 32 are the portions that are used in the subsequent manufacturing steps to hold the tabs 32, 32 and to perform the steps, and are very important in making the manufacturing speed fast. The position in the thickness direction of both end sides of the projecting piece 32 and the ruler of the projecting piece 32 are determined according to the optimum position and size of the operation mode of the manufacturing apparatus. Further, in the mold 26 used for injection molding, it is possible to form a single acquisition form of a substrate 3 having a tab with one shot, or a plurality of multiple acquisition forms at a time. . Next, as shown in Fig. 4(a), the substrate 30 with the tabs obtained by the injection molding is attached to the first reflection preventing sheet 18a' via the adhesive material 16a on one surface thereof. The second reflection preventing sheet 18b is attached to one surface through the adhesive material 16b. The reflection preventing sheet of the substrate 30 with the tabs is disposed such that the adhesive material faces the surface side of the substrate 30 with the tabs, and the reflection preventing sheet is placed on the substrate 30 with the tabs. This is carried out by pressing the surface of the sheet to prevent reflection of the sheet by a rubber roller or the like. Further, it is preferable to process one surface and/or the other surface of the substrate 30 with the tabs by a surface treatment method to be described later before the first reflection preventing sheet 18a and the second reflection preventing sheet 18b are attached. , in advance 322776 19 201213135 first promotes the reflection to prevent the adhesion of the sheet. Further, the first reflection preventing sheet 18a and the second reflection preventing sheet igb which are attached to the substrate 30 with the tabs after the surface treatment are preferably set to have a larger size than the substrate 12. This is because the reflection preventing sheet can be attached to the entire surface of the substrate 12 even when the first reflection preventing sheet 18a and the second reflection preventing sheet 18b are attached to the substrate 30 with the tabs. Further, the first reflection preventing sheet 18a and the second reflection preventing sheet 18b are formed in a roll shape in order to reduce the number of man-hours, and are supplied in a larger size than the substrate 12. After the first reflection preventing sheet 18a is attached to one surface of the substrate 30 having the tabs, the first reflection preventing sheet 18a is cut by laser in accordance with the shape of the substrate as shown in Fig. 4(b). Further, similarly, as shown in Fig. 4(c), after the second reflection preventing sheet 18b is attached to the other surface of the substrate 3A having the tabs, it is fitted as shown in Fig. 4(d). The shape of the substrate is cut by the laser to cut the second reflection preventing sheet 18b. The laser system used can also use short-wavelength lasers or green lasers of ultraviolet wavelengths. However, it is advisable to use a carbon dioxide laser (C〇2 laser) when considering cost performance. When the first reflection preventing sheet 18a and the second reflection preventing sheet 18b are cut, 'the rough cutting is first performed, and then the finishing cut is performed. If it is performed twice, the reflection preventing sheet can be accurately performed. Cutting. Further, the number of times of rough cutting may be one or more times, and the number of times of finishing cutting may be one or more times. As long as it is possible to accurately match the display window 1 of the final form to the final form, it is preferable to perform the cutting in consideration of the size. Therefore, it is preferable to set the cutting cycle time and the appropriate number of times. Further, on the surface of the reflection preventing sheet, a film is formed on the surface of the reflection preventing sheet which has been subjected to rough cutting to prevent the thin opening layer', and then the finishing cut is performed. 4 :; = brushed display window H), when attached to the other side of the surface _ money = with a protruding formation of the printed layer 20 ' as shown in Figure 5 (4) after 18b, such as: Γ 3〇 The other side of the surface is attached with the second reflection preventing sheet IS / 2 (b), and the second reflection preventing thin is subjected to rough cutting 2 = two reflection preventing the sheet from tearing the outer side portion ^ in the rough cutting, The second reflection is prevented from being formed into (4) the protruding substrate 3G is further enlarged - as shown in the open figure (c), the surface of the first reflection preventing sheet igb is formed by the net P The printing layer 20 is printed, and after the heat treatment or ultraviolet irradiation for fixing the printing layer 20 is applied, as shown in FIG. 5 (the second reflection preventing sheet 18b is subjected to finishing cutting, and the second reflection preventing sheet 18b is cut off The outer portion 17b is configured to shape the second reflection preventing sheet 18b into substantially the same shape as the other surface of the substrate 30 with the tabs. Thus, before the formation of the printing layer 20, the printing layer 2 is formed on the surface. The second reflection preventing sheet i8b of the crucible is roughly cut, and the printing layer 20 is formed. Finishing and cutting, which can improve the appearance of the printed appearance and the full-page printing quality to the peripheral edge. In addition, although the printing method is not particularly limited, especially if the 21 322776 201213135 screen printing is used, even the detailed design is It is preferable to be able to print reliably. Further, before the printing layer 20 is formed on the surface of the second reflection preventing sheet 18b, it is preferable to treat the surface of the second reflection preventing sheet 18b by a surface treatment method described later. In order to improve the adhesion between the second reflection preventing sheet 18b and the printed layer 20. Further, in the above-described embodiment, the printed layer 20 is formed only on the surface of the second reflection preventing sheet 18b, but the present invention The display panel 10 is not limited thereto, and for example, the printing layer 20 may be formed only on the surface of the first reflection preventing sheet 18a, or the printing layer may be formed on the surfaces of the first reflection preventing sheet 18a and the second reflection preventing sheet 18b. 20. Next, the substrate 30 with the tabs to which the first reflection preventing sheet 18a and the second reflection preventing sheet 18b are attached is subjected to image inspection to The cut sheet is not protruded, etc., and whether the cutting is performed correctly. Further, the inspection step may be performed in two steps of completing the first reflection preventing sheet 18a and the second reflection preventing sheet 18b each time, or may be completed at the first cutting. The reflection preventing sheet 18a and the second reflection preventing sheet 18b are collected and collected one at a time. Further, by placing the substrate 30 with the tabs in an autoclave (not shown) for high-pressure processing, removal cannot be performed. The microbubbles recognized by the naked eye. Finally, the tabs 3 2 are cut from the substrate 30 with the tabs. This is displayed in the display panel 10 of Fig. 1. In addition, the pursuit is from the viewpoint of appearance quality. When the ridge line portion of the substrate 30 is more beautiful, the ridge line portion after the laser cutting and finishing is mechanically processed to more beautifully modify the 22 322776 201213135. Such a display window gentleman protective sheet (not shown) 0 is different from the actual two shipments, and the package of the present invention is shipped in this type. In the step of obtaining the display window, the manufacturing method can be formed less, so that the system can be reduced to a complete one. <Surface treatment method> The device can be reduced in cost. Next, a method for processing the surface treatment of the substrate and the treatment of the surface of the substrate and/or the other side of the surface of the method 4 4 (the ride with the tab 3 () = the window ig ig. A surface treatment method for preventing the surface of a sheet from being scratched is a surface treatment method which is seldom known at the surface of the present invention, and may be a surface treatment, a corona discharge treatment, or a power treatment. The treatment of primer, etc., At lame), various surface treatment methods of the bottom layer, the hydrophilicity and adhesion treatment of the plastic surface and the ITRO treatment method are suitable: some methods in the Wangli method, especially the so-called flame In the flame treatment method, the flame is oxidized by the surface of the flame. The so-called ITRO treatment means that the oxidized fire which is shouted by the introduced gas is injected into the resin molded article, etc., and the surface is emulsified. By pulverizing the film, the hydrophilicity and the dense formation of the south of the substrate, and the surface treatment of the fire 322776 23 201213135 flame treatment, ITR0 treatment, etc. on the surface of the substrate 12 and/or the other surface of the substrate 12, Even on the substrate 12 When attached to a side surface of the first anti-reflective sheet disposed 18a, and the other surface thereof is provided a second antireflection attached sheet 18b, after applying the heat treatment does not damage the appearance of the antireflection sheet. In addition, when the surface of the second reflection preventing sheet 18b is subjected to surface treatment such as flame treatment or ITR0 treatment, sufficient adhesion to the printed layer 20 can be obtained, so that it can be satisfactorily applied to the second reflection preventing sheet 18b. A printed layer 20 is formed on the surface. In addition, when the ITR0 process is performed as the surface treatment method described above, the hydrophilicity and adhesion of the substrate 12 and the second reflection preventing sheet 18b are excessively increased, and dust or dust becomes excessive depending on the processing conditions. It is easy to adhere to the surface of the substrate 12 and the second reflection preventing sheet 18b subjected to the ITR0 treatment. In this regard, the situation of flame treatment is almost impossible to cause such a problem. In addition, it has been found that the anti-reflection sheet is attached to the substrate 12 which has not been subjected to the surface treatment, and the boundary line which is generated on the surface of the anti-reflection sheet is applied to the adhesive material when a heat treatment or the like is applied thereafter. The thinner the thickness, the easier it is to produce, and the thickness of the adhesive material is significantly less than 10 #m. Further, when it is known that the adhesive material has a certain thickness, even if the antireflection sheet is attached to the substrate 12 which is not subjected to the surface treatment, the above-mentioned boundary line is not easily generated on the surface of the antireflection sheet, and the thickness of the adhesive material is When it is 25//m or more, such a boundary line is hardly generated. The reason for this is presumed as follows. 24 322776 201213135 That is, the 'reverse (four) sheet rubber roll is applied to the substrate 12 of a limited size, so in particular, in the step of attaching on the side degassing: compared to the outer circumference of the substrate 12 The pressure on the central government has become stronger and there is no avoidance. When the surface treatment is not performed, heat treatment or the like is applied in a state in which the difference in adhesion between the outer peripheral portion and the central portion of the substrate 12 due to the strength of the pressing force of the adhesive material and the substrate 12 remains remarkably. (4) As a result of the expansion during heating and the contraction during cooling (4), the boundary of the difference in adhesion force becomes a boundary line and floats. In this case, if the thickness of the adhesive material is more than a certain degree, the difference between the outer peripheral portion of the substrate 12 and the middle force due to the strength of the pressing force of the substrate 12 is moderated, so even if applied Hot standby shows obvious boundary lines. In the case of the flames, etc., the substrate 12 is subjected to ITR 〇 processing and surface treatment, whereby the appearance of the sheet is prevented from being damaged even if a heat treatment or the like is applied thereafter, which is presumed to be because By performing the surface treatment, the adhesion of the substrate 12 is improved, whereby the adhesion force between the center portion and the outer peripheral portion of the substrate 12 can be reduced, and a clear boundary line does not appear even when heat treatment or the like is applied. Therefore, the surface treatment of the substrate 12 may be performed as long as the ifn having a small thickness of the adhesive material is, for example, 25 " m or less. Further, the surface treatment of the second reflection preventing sheet 18b may be performed not on the entire surface of the sheet, but may be performed only in the range in which the printing I 2G is formed. Although the preferred embodiment of the present invention has been described above, the present invention is not limited thereto, and various modifications and additions are possible. (Embodiment) (First Embodiment) A person who has one surface of the counter substrate 12 (substrate 30 with a tab) is prepared (Comparative Example 1-1), and the ITR0 processor (Example 1) is performed. The flame handler (Example 1-2) and the corona discharger (Example 1-3) were pressed, and the first reflection preventing sheet 18a (adhesive layer 10 thick) was pressed by a rubber roller to be attached. . The other surface of each of the substrates 12 is attached by a second anti-reflection sheet 18b (adhesive material 40ym) in a state where the rubber roller is pressed without treatment. Then, the surface of the second reflection preventing sheet 18b was prepared without a processor (Comparative Example 1-1), the ITRO process was performed (Example 1-1), and the flame treatment was performed (Example 1-2). The corona discharge treatment was carried out (Examples 1-3), and the printing layer 20 was partially formed, and then placed in an oven at 80 ° C for 30 minutes to thermally cure the printed layer 20. After the surface of the first reflection preventing sheet 18a is observed, in the case of no processor (Comparative Example 1-1), it is considered that the boundary line due to the strength of the pressing force of the rubber roller at the time of sheet attachment is attached to the appearance. Apparently emerged. Further, even in the case where the corona discharge treatment was carried out (Example 1-3), it was confirmed that there was a boundary line which was slightly caused by the strength of the pressing force of the rubber roller at the time of sheet attachment. On the other hand, in the case where the ITRO processor was performed (Example 1-1) and the flame treatment person (Example 2), such a boundary line was not confirmed on the surface of the first reflection preventing sheet 18a. 26 322776 201213135 In addition, when the surface of the second reflection preventing sheet 18b is observed, there is no processor (Comparative Example 1-1), ITR0 processing is performed (Example 丨), and flame treatment is performed (Example 2) And those who performed the corona discharge treatment (Examples 1-3) did not confirm such a boundary line. In addition, when the adhesion force between the printed layer 20 and the sheet printed on the surface of the second reflection preventing sheet 18b is confirmed by the tape peeling test, the person who has performed the ITR0 processing (the example) and the flame treatment is performed. In the case (Example 1-2), it was confirmed that the peeling strength (evaluation: "〇") was sufficient, and the corona discharge treatment (Example 3) was sufficiently peeled off. The result of the intensity is a poor result (evaluation: △"). In addition, in the case of no processor (comparative example), only the peeling strength (evaluation: "X") which is insufficient in the printing of the layer 2Q with a slight force is obtained. In addition, the ITR0 treatment (the air flow of the gas flow rate, the prQpane gas and the thorough mixing ratio) performed in the present embodiment is air: propane gas: ITRO = 1 〇〇: 4. 1 : 2.7. In addition, the ratio of the air flow rate of the gas in the fire treatment (Example 1-2) to the mixed gas of the propylene gas is air: propane gas = 1 〇〇: 4. 322776 27 201213135 (Table 1)

The one surface was not treated (Comparative Example 2-1), the HR0 process was performed (Example 2-1), the flame treatment was performed (Example 2-2), and the process was carried out. The corona discharge treatment (Example 2-3) was carried out by pressing the first reflection preventing sheet i8a (adhesive layer 20ym thick) with a rubber roller. The other surface of each of the substrates 12 is attached by a second anti-reflection film 18b (adhesive material 4〇em) which is pressed by a rubber roller in an untreated state. Then, the surface of the second reflection preventing sheet 18b was prepared without a processor (Comparative Example 2-1), the ITR0 processor (Example 2_1;), and the flame treatment was performed (Executive 322776 28 201213135, for example, 2_2), and the corona discharge treatment (Examples 2 to 3), and the printing layer 2 was formed in part and in part, and then placed in a furnace of 801 for 3 minutes to heat-print the layer 20. After the surface of the first reflection preventing W18a is observed, in the case of no processor (Comparative Example 2-1), it is considered that the boundary line due to the strength of the pressing force of the rubber roller when the sheet is occupied is attached to the appearance. Obviously emerged. Further, even in the case where the corona discharge treatment was carried out (Example 2_3), it was confirmed that there was a boundary line which was considered to be caused by the strength of the pressing force of the rubber roller at the time of sheet attachment. On the other hand, in the case where the itr〇 processor (Example 2-1)' and the flame-treated person (Example 2_2) were on the surface of the first-reflection preventing sheet 18a, such a boundary line was not confirmed. 'Observation of the surface of the second reflection preventing sheet 18b, no processor (Comparative Example 2-1), ITR〇 processing (Example 2_丨), flame treatment (Real 2_2), And those who performed electrical electricity processing (Example 2-3) did not confirm such a boundary line. In addition, when the adhesion force between the printed layer 2〇 and the sheet printed on the surface of the second reflection preventing sheet 18b was confirmed by the tape peeling test, the person who performed the ITR0 treatment (Example 2_υ, and the flame treatment was performed) In the case of the example 2-2), it was confirmed that the peeling strength was sufficient (evaluation: "〇"), and the corona discharge treatment (Example 2_3) was found to have a sufficient peel strength. The result (evaluation: "△"). In addition, in the case of the non-processor (Comparative Example 2_υ, only the insufficient peeling 322776 29 201213135 strength (evaluation: "X") which is peeled off only by the slight force of the printed layer 20 is obtained.
