Description

Laminated glass with protective film

本發明係關於具有保護膜之積層玻璃。The present invention relates to laminated glass with protective film.

近年來，具有高品質質地、高強度及優良耐熱性之玻璃板作為顯示裝置面板用於保護顯示裝置之目的之應用有所增加。作為用於車載儀器(例如車輛導航系統或儀錶板)之顯示器之面板，或作為用於移動裝置(例如行動電話)之顯示器之面板，自防止背景反射及污跡黏著之觀點而言，需要配備有抗反射層或防污層之面板。此外，自在顯示裝置上安裝面板時保護產品之觀點而言，需要將最終將自面板剝離之保護膜黏貼在面板之頂面側(顯示器表面)上(參見專利文件1及專利文件2)。專利文件1：WO2011/148990 專利文件2：WO2011/118367。In recent years, the use of glass plates with high-quality texture, high strength and excellent heat resistance as display device panels for the purpose of protecting display devices has increased. As a display panel for in-vehicle devices (such as car navigation systems or dashboards), or as a display panel for mobile devices (such as mobile phones), from the viewpoint of preventing background reflection and stain adhesion, it needs to be equipped Panels with anti-reflective layer or anti-fouling layer. In addition, from the viewpoint of protecting the product when installing the panel on the display device, it is necessary to stick the protective film finally peeled from the panel on the top side (display surface) of the panel (see Patent Document 1 and Patent Document 2). Patent Document 1: WO2011/148990 Patent document 2: WO2011/118367.

在用作顯示裝置面板之積層玻璃上，經由黏著劑介質黏貼保護膜。然而，在剝離保護膜時，發生如下情形：其中構成在透明基板主表面上形成之抗反射層或防污層之材料之至少一部分藉由在保護膜上形成之黏著劑層之黏著劑剝離，或構成黏著劑層之黏著劑保留在積層玻璃表面之至少一部分上，端視構成添加至黏貼在積層玻璃上之保護膜之黏著劑層之黏著劑之黏著性而定。由於此一困難可造成以下問題：在保護膜黏貼區域與非保護膜黏貼區域之間之邊界處，色彩之色調變化，且該邊界因此變得顯著而影響視覺鑒賞。該問題之主要原因在於，低反射層之附接降低表面反射率，引起色彩之色調的微小變化在視覺上易於識別之情況，且由於其中利用光學干涉，低反射層在表面受膜厚度折射率變化之影響而造成色彩之色調及反射性變化。此外，在保護膜之大小大於用作面板之積層玻璃之情形中，可造成以下問題：例如在顯示裝置上安裝面板時保護膜陷於顯示裝置外殼之間隙中，從而自生產觀點而言造成困難。本發明之具有保護膜之積層玻璃係具有保護膜之積層玻璃，其含有：積層玻璃，其至少含有具有第一主表面及第二主表面之透明基板、第一主表面上方之抗反射層及設於第二主表面之周邊區域上方之遮光層，及具有黏著劑層之保護膜，其中具有黏著劑層之保護膜黏貼在積層玻璃上之如下位置：在積層玻璃之前視圖中，具有黏著劑層之保護膜之周邊邊緣相對於遮光層之內周側朝向外周側定位，且其相對於遮光層之外周側朝向內周側定位，及積層玻璃與黏著劑層之間之黏著性為0.01 N/10 mm至0.3 N/10 mm。在本發明之具有保護膜之積層玻璃中，積層玻璃較佳進一步含有在該透明基板之相對側之在該抗反射層上方之防污層，且該積層玻璃與該黏著劑層之間之黏著性為0.01 N/10 mm至0.05 N/10 mm。在本發明之具有保護膜之積層玻璃中，較佳地在長度t定義為連接該積層玻璃最表層表面之周邊邊緣上之任意點與通過該任意點自該積層玻璃最表層表面之周邊邊緣向該保護膜之周邊邊緣延伸之垂直定向之直線與該保護膜之最近周邊邊緣交叉之點之線段之長度時，該長度t大於0 mm且小於10 mm。在本發明之具有保護膜之積層玻璃中，較佳地，該遮光層係在自該透明基板之該第二主表面之外周側超過0 mm至低於30 mm之範圍內形成。在本發明之具有保護膜之積層玻璃中，較佳地，黏著劑層含有黏著劑，該黏著劑包含基於丙烯酸之黏著劑或基於聚胺基甲酸酯之黏著劑作為主要成份。在本發明之具有保護膜之積層玻璃中，較佳地，該積層玻璃在形成該遮光層之區域中在由該抗反射層形成之表面具有2%或更低之光反射率，其中該光反射率係藉由移除源自背側反射之效應來測定。在本發明之具有保護膜之積層玻璃中，較佳地，該積層玻璃在形成該遮光層之區域中在藉由該抗反射層及該防污層形成之表面具有2%或更低之光反射率，其中該光反射率係藉由移除源自背側反射之效應來測定。在本發明之具有保護膜之積層玻璃中，較佳地，防污層係由含有含氟化合物之防污劑形成。在本發明之具有保護膜之積層玻璃中，較佳地，透明基板之第一主表面具有凹凸。在本發明之具有保護膜之積層玻璃中，較佳地，透明基板係化學韌化玻璃。根據如上文所提及之本發明，構成保護膜之黏著劑層之黏著劑之黏著性經調節落在指定範圍內，且由此使得可能防止黏著劑保留在積層玻璃最表層表面之至少一部分上並抑制構成抗反射層、防污層或諸如此類之材料之至少一部分被剝離，從而獲得在顯示器表面上在不同色調之間無視覺可識別邊界之良好外觀。此外，在本發明之具有保護膜之積層玻璃中，具有黏著劑層之保護膜黏貼在積層玻璃上之如下位置：保護膜之周邊邊緣相對於遮光層之內周側朝向外周側定位，且另外，其相對於遮光層之外周側朝向內周側定位，由此在安裝具有保護膜之積層玻璃作為顯示裝置面板時增強處置性質。On the laminated glass used as the panel of the display device, the protective film is pasted through the adhesive medium. However, when the protective film is peeled off, a situation occurs in which at least a part of the material constituting the antireflection layer or the antifouling layer formed on the main surface of the transparent substrate is peeled off by the adhesive of the adhesive layer formed on the protective film, Or the adhesive constituting the adhesive layer remains on at least a part of the surface of the laminated glass, depending on the adhesiveness of the adhesive constituting the adhesive layer of the protective film attached to the laminated glass. Due to this difficulty, the following problems may be caused: at the boundary between the protective film pasting area and the non-protecting film pasting area, the hue of the color changes, and the boundary becomes prominent and affects visual appreciation. The main reason for this problem lies in the fact that the attachment of the low-reflection layer reduces the surface reflectivity, causing small changes in the hue of the color to be easily recognized visually, and because of the use of optical interference, the low-reflection layer is affected by the film thickness and refractive index on the surface. The effect of the change causes the color tone and reflectivity to change. In addition, in the case where the size of the protective film is larger than the laminated glass used for the panel, the following problems may be caused: for example, the protective film is trapped in the gap of the display device housing when the panel is installed on the display device, thereby causing difficulties from the production point of view. The laminated glass with a protective film of the present invention is a laminated glass with a protective film, which contains: Laminated glass comprising at least a transparent substrate having a first main surface and a second main surface, an anti-reflection layer above the first main surface, and a light-shielding layer provided above the peripheral area of the second main surface, and Protective film with adhesive layer, The protective film with the adhesive layer is pasted on the laminated glass at the following position: In the front view of the laminated glass, the peripheral edge of the protective film with the adhesive layer is positioned relative to the inner peripheral side of the light-shielding layer toward the outer peripheral side, and they are opposite Positioning on the outer peripheral side of the light-shielding layer toward the inner peripheral side, and The adhesion between the laminated glass and the adhesive layer is 0.01 N/10 mm to 0.3 N/10 mm. In the laminated glass with the protective film of the present invention, the laminated glass preferably further contains an antifouling layer on the opposite side of the transparent substrate above the anti-reflection layer, and the adhesion between the laminated glass and the adhesive layer The performance ranges from 0.01 N/10 mm to 0.05 N/10 mm. In the laminated glass with a protective film of the present invention, the length t is preferably defined as connecting any point on the peripheral edge of the outermost surface of the laminated glass and passing through the arbitrary point from the peripheral edge of the outermost surface of the laminated glass. When the length of the line segment at the point where the perpendicularly oriented straight line extending from the peripheral edge of the protective film crosses the nearest peripheral edge of the protective film, the length t is greater than 0 mm and less than 10 mm. In the laminated glass with a protective film of the present invention, preferably, the light shielding layer is formed in a range from more than 0 mm to less than 30 mm from the outer peripheral side of the second main surface of the transparent substrate. In the laminated glass with a protective film of the present invention, preferably, the adhesive layer contains an adhesive containing an acrylic-based adhesive or a polyurethane-based adhesive as a main component. In the laminated glass with a protective film of the present invention, preferably, the laminated glass has a light reflectivity of 2% or less on the surface formed by the anti-reflection layer in the region where the light-shielding layer is formed, wherein the light Reflectance is measured by removing the effects originating from the backside reflection. In the laminated glass with the protective film of the present invention, preferably, the laminated glass has 2% or less of light on the surface formed by the anti-reflection layer and the anti-fouling layer in the area where the light-shielding layer is formed. Reflectance, where the light reflectance is measured by removing the effect from the backside reflection. In the laminated glass with a protective film of the present invention, preferably, the antifouling layer is formed of an antifouling agent containing a fluorine-containing compound. In the laminated glass with a protective film of the present invention, preferably, the first main surface of the transparent substrate has unevenness.

According to the present invention as mentioned above, the adhesiveness of the adhesive constituting the adhesive layer of the protective film is adjusted to fall within a specified range, and thus it is possible to prevent the adhesive from remaining on at least a part of the surface of the outermost layer of the laminated glass And prevent at least a part of the material constituting the anti-reflection layer, the anti-fouling layer or the like from being peeled off, thereby obtaining a good appearance with no visually recognizable boundary between different tones on the surface of the display. In addition, in the laminated glass with the protective film of the present invention, the protective film with the adhesive layer is stuck on the laminated glass at the following position: the peripheral edge of the protective film is positioned toward the outer peripheral side with respect to the inner peripheral side of the light shielding layer, and in addition , It is positioned toward the inner peripheral side with respect to the outer peripheral side of the light shielding layer, thereby enhancing the handling properties when installing laminated glass with a protective film as a display device panel.

本發明之具有保護膜之積層玻璃參照圖式詳細闡述於下文中。儘管下文以具體實施例闡釋本發明，但不應將本發明視為以任何方式受限於下文關於該等具體實施例之說明，且無需贅言，在不背離本發明之精神及範圍之情況下，若適當，可對多種組份作出各種增加、省略、修改、取代及其他變化。圖1至圖3係橫斷面圖，其圖解說明本發明之具有保護膜之積層玻璃之例示實施例。在下文中，具有保護膜之積層玻璃有時稱為「載有保護膜之積層玻璃」。類似地，具有黏著劑層之保護膜有時稱為「附接黏著劑層之保護膜」。順便提及，在第一至第三實施例中之每一者所闡釋之載有保護膜之積層玻璃1設於顯示板之影像顯示側(觀察者側)上時，其可用作保護顯示板之面板。 (第一實施例) 本發明之具有保護膜之積層玻璃之第一實施例係如圖1中所圖解說明。載有保護膜之積層玻璃1含有附接黏著劑層之保護膜80以及積層玻璃90，該積層玻璃90含有具有第一主表面及第二主表面之透明基板10、在透明基板10之第一主表面上形成之抗反射層20及在透明基板10之第二主表面之周邊部分上形成之遮光層70。附接黏著劑層之保護膜80黏貼於積層玻璃90上。在積層玻璃90之前視圖中，附接黏著劑層之保護膜80黏貼於積層玻璃90之如下位置：附接黏著劑層之保護膜80之周邊邊緣相對於遮光層70之內周側朝向外周側定位，且相對於遮光層70之外周側朝向內周側定位。此外，作為積層玻璃90之最表層表面形成之抗反射層20與黏著劑層40之間之黏著性經調節落在0.01 N/10 mm至0.3 N/10 mm範圍內。藉由將黏著劑層40與欲作為積層玻璃90主表面形成之抗反射層20之間之黏著性調節至落在0.01 N/10 mm至0.3 N/10 mm範圍內，可能避免構成黏著劑層之黏著劑保留在積層玻璃90最表層表面之至少一部分上。藉由將黏著劑層40與欲作為積層玻璃90主表面形成之抗反射層20之間之黏著性調節至落在0.01 N/10 mm至0.3 N/10 mm範圍內，可能避免構成作為積層玻璃90最表層表面形成之抗反射層20之材料之至少一部分藉由構成黏著劑層之黏著劑剝離。此外，根據本發明之具有保護膜之積層玻璃之第一實施例，附接黏著劑層之保護膜80黏貼於積層玻璃90上，使得在長度t定義為連接積層玻璃90最表層表面之周邊邊緣上之任意點與通過該任意點自該積層玻璃最表層表面之周邊邊緣向該保護膜之周邊邊緣延伸之垂直定向之直線與該保護膜之最近周邊邊緣交叉之點之線段之長度時，該長度t大於0 mm且小於10 mm (參見圖4)。在本實施例中，在透明基板10第二主表面之周邊區域上形成之遮光層70形成帶狀區域，該帶狀區域具有自周邊邊緣朝向透明基板10第二主表面中心之預定寬度。 (第二實施例) 本發明之具有保護膜之積層玻璃之第二實施例係如圖2中圖解說明。載有保護膜之積層玻璃1含有附接黏著劑層之保護膜80以及積層玻璃90，該積層玻璃90含有具有第一主表面及第二主表面之透明基板10、在透明基板10之第一主表面上形成之抗反射層20及在透明基板10之第二主表面之周邊部分上形成之遮光層70。本發明之具有保護膜之積層玻璃之第二實施例中之積層玻璃90進一步設有抗反射層主表面上之防污層30。附接黏著劑層之保護膜80黏貼於積層玻璃90上。在積層玻璃90之前視圖中，附接黏著劑層之保護膜80黏貼於積層玻璃90之如下位置：附接黏著劑層之保護膜80之周邊邊緣相對於遮光層70之內周側朝向外周側定位，且相對於遮光層70之外周側朝向內周側定位。此外，作為積層玻璃90最表層表面形成之防污層30與黏著劑層40之間之黏著性經調節落在0.01 N/10 mm至0.05 N/10 mm範圍內。藉由將黏著劑層40與欲作為積層玻璃90主表面形成之防污層30之間之黏著性調節至落於0.01 N/10 mm至0.05 N/10 mm範圍內，可能避免構成黏著劑層之黏著劑保留在積層玻璃90最表層表面之至少一部分上。藉由將黏著劑層40與欲作為積層玻璃90主表面形成之防污層30之間之黏著性調節至落於0.01 N/10 mm至0.05 N/10 mm範圍內，可能避免構成作為積層玻璃90最表層表面形成之防污層30之材料之至少一部分藉由構成黏著劑層之黏著劑剝離。此外，根據本發明之具有保護膜之積層玻璃之第二實施例，附接黏著劑層之保護膜80黏貼於積層玻璃90上，使得在長度t定義為連接積層玻璃90最表層表面之周邊邊緣上之任意點與通過該任意點自設有防污層之積層玻璃最表層表面之周邊邊緣向保護膜周邊邊緣延伸之垂直定向之直線與該保護膜之最近周邊邊緣交叉之點之線段之長度時，該長度t大於0 mm且小於10 mm (參見圖4)。 (第三實施例) 本發明之具有保護膜之積層玻璃之第三實施例係如圖3中圖解說明。本發明之第三實施例係係如下實施例：在如第一實施例所呈現，其中設有抗反射層20之積層玻璃90中，或在如第二實施例所呈現，其中按此順序設有抗反射層20及防污層30之積層玻璃90中，在透明基板10之第一主表面與抗反射層20之間進一步形成防眩光層60。在圖3圖解說明如下實施例：在具有防污層30之積層玻璃(第二實施例)中，在透明基板10之第一主表面與抗反射層20之間形成防眩光層60。然而，無需贅言，亦可在不具有防污層30之積層玻璃中(第一實施例)形成防眩光層60。＜積層玻璃＞積層玻璃至少含有具有第一主表面及第二主表面之透明基板、在透明基板之第一主表面上/上方形成之抗反射層及在毗連透明基板第二主表面之端面之周邊區域上/上方形成之遮光層。積層玻璃可進一步含有在抗反射層主表面上/上方之防污層。在積層玻璃中，可在透明基板之第一主表面與抗反射層之間形成防眩光層。＜具有黏著劑層之保護膜＞藉由將黏著劑層附接至保護膜之一側形成具有黏著劑層之保護膜。為在生產製程及產品運輸期間提供對安裝在顯示裝置上之顯示板之保護，具有黏著劑層之保護膜保持黏貼在積層玻璃之最表層表面上，由此保護積層玻璃。在使用顯示裝置時，自積層玻璃剝離具有黏著劑層之保護膜。藉由調節構成欲附接至保護膜之黏著劑層之黏著劑之黏著性，可能避免構成黏著劑層之黏著劑保留在積層玻璃最表層表面之至少一部分上。藉由調節構成欲附接至保護膜之黏著劑層之黏著劑之黏著性，可能避免構成作為積層玻璃最表層表面形成之抗反射或防污層之材料之至少一部分藉由構成黏著劑層之黏著劑剝離。具有黏著劑層之保護膜黏貼於積層玻璃之最表層表面上。具有黏著劑層之保護膜黏貼在積層玻璃上之如下位置：在自前側觀察積層玻璃時，保護膜之周邊邊緣相對於遮光層之內周側朝向外周側定位，且相對於遮光層之外周側朝向內周側定位。因此，在安裝積層玻璃作為顯示裝置(例如液晶顯示器(LCD)、電漿顯示板(PDP)或電發光顯示器(ELD))之面板時，可能減少因例如具有黏著劑層之保護膜陷於裝置外殼中造成之困難，且由此在顯示裝置上安裝具有保護膜之積層玻璃時增強處置性質。術語「具有黏著劑層之保護膜之周邊邊緣」係指遠離具有黏著劑層之保護膜之中心之邊緣。一般而言，具有黏著劑層之保護膜具有矩形形狀，且在矩形形狀之情形中，周邊邊緣之至少一部分係由直線形成。若適當，具有黏著劑層之保護膜之形狀因應積層玻璃之形狀變化，且因此周邊邊緣之至少一部分可由曲線形成。另外，具有黏著劑層之保護膜黏貼在積層玻璃上之如下位置：在長度t定義為連接積層玻璃最表層表面之周邊邊緣上之任意點與通過該任意點自該積層玻璃最表層表面之周邊邊緣向該保護膜之周邊邊緣延伸之垂直定向之直線與具有黏著劑層之保護膜之最近周邊邊緣交叉之點之線段之長度時，該長度t大於0 mm且小於10 mm。因此，可能在顯示裝置上安裝具有保護膜之積層玻璃時增強處置性質。保護膜較佳經放置使得其周邊邊緣存於遠離積層玻璃之周邊邊緣朝向積層玻璃中心小於10 mm之位置正上方。此乃因保護積層玻璃免受衝擊及諸如此類之目的變得易於達成所致。此外，出於增強自積層玻璃剝離具有黏著劑層之保護膜之便捷性之目的，可設有使得易於拾取保護膜之邊緣之舌片段，或可在具有黏著劑層之保護膜之周邊邊緣之至少一部分中設有其上未形成黏著劑層之區域。因此，具有黏著劑層之保護膜可易於自積層玻璃剝離。偶然地，基於使得易於剝離之目的所設之舌片段可延伸出周邊至不影響處置性質之程度。在具有抗反射層及/或防污層之積層玻璃與具有黏著劑層之保護膜結合在一起之情況下，可採取手動工作。然而，自生產效率之觀點而言較佳地，以捲起之卷軸形式供應之具有黏著劑層之保護膜藉助橡膠輥或諸如此類經受積層，或根據積層玻璃之尺寸預先將具有黏著劑層之保護膜切割成片形保護膜，然後藉助貼標機、密封黏貼機或諸如此類經受積層。＜黏著劑層＞在保護膜之一側上設置黏著劑層以形成附接黏著劑層之保護膜。適於黏著劑層之黏著劑係黏著度使得在自積層玻璃剝離具有黏著劑層之保護膜時，黏著劑甚至抵抗保留在積層玻璃最表層表面之至少一部分上之黏著劑。適於黏著劑層之黏著劑係黏著度使得在自積層玻璃剝離具有黏著劑層之保護膜時抑制黏著劑甚至剝離構成積層玻璃之抗反射層或防污層之材料之至少一部分之黏著劑。作為如上文所指定之黏著劑層之黏著劑，根據黏著性及剝離性質，較佳可使用基於丙烯酸之黏著劑、基於聚胺基甲酸酯之黏著劑及諸如此類。只要黏著劑層具有0.01 N/10 mm或更大之黏著性，黏著劑即可均勻黏著至積層玻璃之最表層表面，且在將附接黏著劑層之保護膜黏貼至積層玻璃時容許黏著劑層均勻黏著至作為積層玻璃最表層表面形成之抗反射層或防污層之表面處理劑之表面。另外，無需擔心在運輸等期間因保護膜自積層玻璃發生脫層而損害作為保護膜之功能。只要黏著劑層具有0.3 N/10 mm或更小之黏著性，黏著劑層即具有適度黏著，且因此無需擔心引起缺陷條件使得在剝離附接黏著劑層之保護膜時，用於作為積層玻璃最表層表面形成之抗反射層之表面處理劑之至少一部分以大於所需之量藉由黏著劑剝離，或構成附接黏著劑層之保護膜之黏著劑層之黏著劑仍留在積層玻璃最表層之至少一部分中，且因此可見性降低並發生沾污。在將附接黏著劑層之保護膜黏貼於形成抗反射層作為最表層表面之積層玻璃上情形中，黏著劑層與抗反射層之間之黏著性較佳係0.03 N/10 mm至0.3 N/10 mm，且更佳係0.05 N/10 mm至0.15 N/10 mm。藉由將黏著性調節至較佳範圍內之數值，可能抑制黏著劑留在抗反射層上及抑制構成抗反射層之材料藉由黏著劑剝離。在將附接黏著劑層之保護膜黏貼至形成防污層作為最表層表面之積層玻璃情形中，黏著劑層與防污層之間之黏著性較佳係0.01 N/10 mm至0.05 N/10 mm，且更佳係0.02 N/10 mm至0.04 N/10 mm。藉由將黏著性調節至較佳範圍內之數值，可能抑制黏著劑保留在防污層上及抑制構成防污層之材料藉由黏著劑剝離。具體而言，黏著劑往往保留在防污層表面上或構成防污層之材料易於藉由黏著劑剝離。因此應瞭解，將黏著劑層與防污層之間之黏著性調節至低於黏著劑層與抗反射層之間之黏著性之數值。根據附接黏著劑層之保護膜之黏著劑層相對於抗反射層或防污層之黏著能力及剝離能力，黏著劑層之厚度較佳係3 μm至50 μm，且更佳係5 μm至25 μm。＜保護膜＞關於保護膜無特定限制，只要其係由樹脂製得且具有膜狀形式即可。另外，保護膜可具有單層結構或藉由使複數個層積層形成之多層結構，該複數個層包括抗靜電層、硬塗層及易黏著層。此外，保護膜可以任何色彩著色以避免忘記自積層玻璃剝離具有黏著劑層之保護膜。作為保護膜，可利用例如聚酯膜，例如聚對苯二甲酸乙二酯膜；聚烯烴膜，例如聚乙烯膜及聚丙烯膜；聚氯乙烯膜或諸如此類。在該等膜中，聚酯膜在與黏著劑層之黏著性、耐久性及光學特徵方面較佳。保護膜關於其厚度無特定限制，但厚度較佳係例如5 μm至100 μm。在15 μm至75 μm範圍內之厚度更佳，此乃因具有此一範圍厚度之膜易於彎曲且易於剝離。另一方面，薄於5 μm之保護膜可能無法獲得對積層玻璃之足夠保護，且厚於100 μm之保護膜可使成本增加。＜透明基板＞透明基板之實例包括通常使用之玻璃板，例如自鈉鈣玻璃、硼矽酸鹽玻璃、鋁矽酸鹽玻璃及無鹼玻璃製得之板、自具有各種組成之無機材料製得之無機玻璃板及透明樹脂板。最適玻璃板之材料之實例包括玻璃材料，例如鈉鈣玻璃、石英玻璃、水晶玻璃及藍寶石玻璃。在該等材料中，較佳者係鐵含量較低且藍色調較少之高度透明之玻璃。作為透明樹脂板之材料，高度透明之樹脂材料係適宜的。透明樹脂板之實例包括聚酯樹脂，例如聚碳酸酯及聚對苯二甲酸乙二酯；聚烯烴樹脂，例如聚丙烯、聚氯乙烯；丙烯酸樹脂、聚醚碸、聚芳酯、三乙醯基纖維素及聚甲基丙烯酸甲酯。作為透明基板，玻璃板最佳，此乃因其不僅具有高透明度，且亦具有耐光性、耐熱性、低折射性、高平整度準確性、表面抗刮性及高機械強度。出於增加玻璃板安全性之目的，可提高機械強度。為提高玻璃板之機械強度，使玻璃板預先經受韌化處理。韌化處理之實例包括藉由使玻璃板暴露於高溫氣氛然後在空氣中冷卻玻璃板實現之物理韌化，及藉由將玻璃板浸沒於含有鹼金屬之熔融鹽中以用存於熔融鹽中且原子直徑大之鹼金屬(離子)置換存於玻璃板最外表面中且原子直徑小之鹼金屬(離子)實現之化學韌化。尤其在使用薄玻璃板之情形中，所用玻璃板較佳係已經歷化學韌化之玻璃板(亦稱為化學韌化玻璃)。作為透明基板之化學韌化玻璃較佳滿足以下條件。具體而言，較佳地，玻璃基板之表面壓應力(下文縮寫為CS)為400 MPa至1,200 MPa，且更佳為700 MPa至900 MPa。自實際強度觀點而言，400 MPa或更大之CS足夠。另一方面，只要玻璃基板具有1,200 MPa或更小之CS，玻璃基板即可耐受其自身之壓應力且無自發破裂之可能性。在使用本發明之載有保護膜之積層玻璃1作為顯示裝置或諸如此類之面板(蓋玻璃)之情形中，玻璃基板之CS較佳在700 MPa至850 MPa範圍內。此外，較佳地，玻璃基板之應力值深度(下文稱為DOL)為15 μm至50 μm，且較佳為20 μm至40 μm。只要玻璃基板具有15 μm或更大之DOL，既無需擔心玻璃基板易於刮傷及破裂。另一方面，只要玻璃基板具有40 μm或更小之DOL，玻璃基板可耐受其自身壓應力且無自發破裂之可能性。在使用本發明之載有保護膜之積層玻璃1作為顯示裝置或諸如此類之面板(蓋玻璃)之情形中，較佳地，玻璃基板之DOL在25 μm至35 μm範圍內。就機械強度而言，藍寶石玻璃亦適宜作為玻璃基板。透明基板通常平滑且具有矩形形狀。若適當，透明基板所需形狀可因應顯示裝置上之顯示板之形狀、顯示裝置之設計、顯示裝置之安裝位置等而變化。換言之，透明基板之形狀不限於平滑幾何學及矩形形狀。舉例而言，透明基板可為表面上具有凹性及凸性之圖案化玻璃，且其可具有多邊形形狀、圓形形狀或橢圓形形狀。另外，透明基板可不僅係平整玻璃板亦可係具有彎曲表面之玻璃板。術語「透明基板之周邊邊緣」係指遠離透明基板中心之端側。一般而言，透明基板具有矩形形狀，且在矩形形狀之情形中，周邊邊緣之至少一部分係由直線形成。若適當，透明基板之形狀因應顯示板之形狀或諸如此類而變化，且因此周邊邊緣之至少一部分可由曲線形成。透明基板之尺寸係根據顯示板之尺寸或使用顯示裝置之目的適當選擇。舉例而言，在用作移動裝置之蓋玻璃之情形中，透明基板之大小較佳在30 mm × 50 mm至300 mm × 400 mm範圍內，且其厚度在0.1 mm至2.5 mm範圍內；而在用於車輛導航系統、操縱板、儀錶板或諸如此類之顯示器中之情形中，透明基板之大小較佳在50 mm × 100 mm至2,000 mm × 1,500 mm範圍內且其厚度在0.5 mm至4 mm範圍內。然而，透明基板關於其厚度無特定限制，且玻璃板只要厚度為10 mm或更低即可用作透明基板。關於機械強度、透明度等，用作透明基板之玻璃板之厚度通常為約0.1 mm至6 mm。尤其在使用玻璃板作為車載顯示裝置中之透明基板之情形中，需要玻璃板之安全性，且因此自機械強度之觀點而言，其厚度較佳在0.2 mm至2 mm範圍內。在出於高效實施化學韌化處理之目的使用化學韌化玻璃之情形中，玻璃基板之適宜厚度通常為5 mm或更低，且較佳為3 mm或更低。在使用透明樹脂板之情形中，板之適宜厚度為2 mm至10 mm。基板厚度愈小，光吸收減輕愈多，且因此就改良可見性亦及透明度而言，玻璃板之使用較佳。另外，不需要透明基板一定具有由單層形成之單層結構，且其可具有由複數個層形成之多層結構，例如積層玻璃結構。＜抗反射層＞抗反射層係出於經由抑制環境光反射提高顯示器影像品質之目的形成之層，且其通常在透明基板之第一主表面上/上方形成。在已對透明基板之第一主表面實施防眩光處理之情形中，適當地，抗反射層20係在藉由防眩光處理產生之防眩光層60上/上方形成。抗反射層關於其結構無特定限制，只要結構容許將光反射降低至某一範圍即可。舉例而言，抗反射層可具有包括低折射率層及高折射率層之積層結構。在本文中，高折射率層係指如使用550 nm波長之光所量測，折射率為例如1.9或更高之層，而低折射率層係指如使用550 nm光所量測，折射率為例如1.6或更低之層。關於抗反射層中高折射率層及低折射率層之數目，可採取包括各一個高折射率層及低折射率層之形式，或可形成具有各自一個以上高折射率層及低折射率層之結構。在採取包括各一個高折射率層及低折射率層之形式的情形中，適當地，高折射率層及低折射率層按所述順序堆疊在透明基板之主表面上。另一方面，在形成具有各自一個以上高折射率層及低折射率層之結構之情形中，適當地採取包括按所述順序交替堆疊之高折射率層及低折射率層之形式。對於增強抗反射性能，較佳地，抗反射層係其中兩個或更多個層彼此上下堆疊之積層。積層較佳具有總計2至8個彼此上下堆疊之層，更佳總計2至6個彼此上下堆疊之層，且進一步較佳總計2至4個彼此上下堆疊之層。如上文所提及，本文中較佳之積層係其中高折射率層及低折射率層交替堆疊且高折射率層及低折射率層之總數在上文所指定範圍內之積層。另外，可在不影響光學特徵之範圍內添加其他層。舉例而言，為防止Na自玻璃基板擴散，可在玻璃與第一層之間插入SiO₂ 膜。高折射率層及低折射率層各自之主要成份無特定限制，且其可在考慮所需抗反射程度及生產力之後經選擇。高折射率層中主要成份之實例包括氧化鈮(Nb₂ O₅ )、氧化鈦(TiO₂ )、氧化鋯(ZrO₂ )、氧化鉭(Ta₂ O₅₎ 、氧化鋁(Al₂ O₃ )及氮化矽(SiN)。一或多個選自該等材料之種類可較佳用作高折射率層中之主要成份。低折射率層中之主要成份之實例包括氧化矽(尤其二氧化矽SiO₂ )、含有Si-Sn混合氧化物之材料、含有Si-Zr混合氧化物之材料及含有Si-Al混合氧化物之材料。一或多個選自該等材料之種類可較佳用於低折射率層中。自生產力及折射率之觀點而言，較佳地，高折射率層係由一個選自氧化鈮、氧化鉭或氮化矽之種類構成，且低折射率層係由氧化矽構成。抗反射層可適宜地藉由使用在其欲形成於其上之表面上直接形成無機薄層之方法、經由使用蝕刻技術或諸如此類實施表面處理之方法或乾式製程(例如化學氣相沈積(CVD)製程或物理氣相沈積(PVD)製程，尤其作為物理氣相沈積製程中之一者之真空沈積製程或濺鍍製程)來形成。亦可能採取其中抗反射層及防污層按所述順序設於透明基板之第一主表面上/上方之形式。在此情形中，在意欲使得易於將防污層施加至抗反射層時，抗反射層可藉由濕式製程形成。作為藉由濕式製程形成之抗反射層之實例，可提及含有低折射率粒子之層，尤其在用作黏合劑之基質成份中含有低折射率粒子之層。或者，抗反射層可藉由使用將具有抗反射功能之透明樹脂膜黏貼於透明基板上之方法而設置。抗反射層之厚度較佳為100 nm至500 nm。有利地將抗反射層之厚度調節至100 nm或更大，此乃因此一厚度容許有效降低環境光之反射。＜防污層＞防污層至少具有撥油性或親脂性。防污層可具有防止不同污跡黏著之功能，該等污跡不僅包括指紋痕跡且亦包括汗液及灰塵，使得易於擦除該等污跡或使該等污跡不顯著，且由此保持顯示器表面清潔。另外，防污層可在觸摸面板操作期間容許手指無阻礙地平滑滑動。關於防污層之性質，較佳地，藉由在抗反射層上/上方設置防污層，作為積層玻璃之最表層表面形成防污層。作為形成防污層之方法，可利用例如真空蒸發法(乾式方法)，其中含氟有機化合物或諸如此類在真空室中蒸發且沈積於抗反射層表面上，或利用將含氟有機化合物或諸如此類溶解於有機溶劑中以製備具有預定濃度之溶液且將溶液施加至抗反射層表面之方法(濕式方法)。若適當，乾式方法可選自離子束輔助沈積法、離子鍍法、濺鍍法或電漿CVD法，而濕式方法可適當地選自旋塗法、浸塗法、澆鑄法、狹縫塗佈法或噴霧法。可採取乾式方法及濕式方法二者。關於抗刮性，較佳使用乾型膜形成方法。防污層(防污劑)中之主要成份可適當地選自可賦予抗污性、撥水性及撥油性之含氟化合物(含氟有機化合物)及諸如此類。該等化合物之實例包括含氟有機矽化合物及含氟可水解化合物。含氟有機化合物之使用可無特定限制，只要其可賦予抗污性、撥水性及撥油性即可。 (含氟有機矽化合物塗層) 在於透明基板主表面上或於防眩光層之經處理表面上形成抗反射層之情形中，較佳在抗反射層表面上設置用於形成防污層之含氟有機矽化合物塗層。另一方面，在使用已經歷表面處理(例如防眩光處理或化學韌化處理)且表面上無抗反射層之玻璃基板作為透明基板之情形中，較佳地，直接在已經歷此一表面處理之面上形成含氟有機矽化合物塗層。作為形成含氟有機矽化合物塗層之方法之實例，可提及如下方法：藉由使用旋塗法、浸塗法、澆鑄法、狹縫塗佈法、噴霧法等塗佈含有具有氟烷基(例如全氟烷基或具有全氟(聚氧化烯)鏈之氟烷基)之矽烷偶合劑之組合物，然後使經塗佈組合物經受熱處理；或真空蒸發法，其中使含氟有機矽化合物經受氣相沈積，然後進行熱處理。為獲得高黏著性之含氟有機矽化合物塗層，較佳地，經由使用真空蒸發法形成塗層。經由使用真空蒸發法形成含氟有機矽化合物塗層較佳藉由使用含有含氟可水解矽化合物之用於塗層形成之組合物來實施。 (含氟可水解矽化合物) 在涉及防污層時，用於形成含氟有機矽化合物塗層之含氟可水解矽化合物無特定限制，只要所獲得含氟有機矽化合物塗層具有抗污性質(包括撥水性及撥油性)即可。此一含氟可水解矽化合物之具體實例包括各自具有至少一個選自由全氟聚醚基團、全氟伸烷基及全氟烷基組成之群之基團之彼等。防污層亦可藉由使用使具有抗污功能之透明樹脂膜積層之方法而設置。一般而言，在抗反射層上形成之防污層之厚度無特定限制，但其較佳係2 nm至20 nm，更佳2 nm至15 nm，且進一步較佳3至10 nm。只要防污層具有2 nm或更大之厚度，防污層即可產生抗反射層之表面經防污層均勻覆蓋之狀態，且可易於獲得能耐受實際使用之抗刮性。另一方面，只要其厚度為20 mm或更小，積層狀態之防污層可將諸如光反射率及濁度等光學特徵保持良好狀況。＜防眩光層＞意欲向積層玻璃賦予防眩光性質時，防眩光層可設於透明基板之第一主表面上/上方。為賦予防眩光性質，可在透明基板之主表面中形成凹凸。具有凹凸之主表面可係透明基板之至少一個主表面，且凹凸較佳於透明基板之第一主表面中形成。對於形成凹凸之方法，通常已知之方法適用。舉例而言，在使用玻璃基板作為透明基板之情形中，適用者係給予玻璃基板之主表面化學或物理表面處理以形成具有期望表面粗糙度之凹凸之方法，或濕式塗佈方法。作為以化學方式實施防眩光處理之方法之具體實例，可提及給予霜化處理之方法。霜化處理可藉由例如將作為欲處理材料之玻璃基板浸沒於含有氟化氫及氟化銨之混合溶液中來實施。作為以物理方式實施防眩光處理之方法之實例，可提及噴砂處理，其中將載有結晶二氧化矽粉末、碳化矽粉末或諸如此類之加壓空氣流輸送至玻璃基板主表面上；或用其上置有結晶二氧化矽粉末、碳化矽粉末或諸如此類之蘸水刷摩擦玻璃基板主表面之方法。在上文所提及之處理中，於對玻璃基板賦予防眩光處理之方法時較佳為霜化處理，此乃因其幾乎不於所處理材料表面中引起微小裂縫形成，因此其幾乎不引起機械強度降低。已經歷如上文所提及之該化學或物理防眩光處理之玻璃基板主表面較佳經受蝕刻處理以固定表面輪廓。對於蝕刻處理，可利用例如將玻璃板浸沒於作為蝕刻溶液之氟化氫水溶液中之化學蝕刻方法。在經歷如上文所提及之該防眩光處理及後續蝕刻處理後，玻璃基板主表面較佳具有0.01 μm至0.5 μm之表面粗糙度(均方根粗糙度，RMS)。表面粗糙度(RMS)更佳係0.01 μm至0.3 μm，且進一步更佳係0.02 μm至0.2 μm。藉由將表面粗糙度(RMS)調節至落於上文所指定範圍內，可在防眩光處理後控制玻璃基板之濁度值落於1%至30%之範圍內，從而對設有抗反射層之透明基板10賦予優良防眩光性質。附帶說明，濁度值係JIS K 7136 (2000)中指定之值。關於形成防眩光層之方法，防眩光層可經由使具有防眩光功能之透明樹脂膜及透明基板積層而設置。＜遮光層＞在透明基板第二主表面之周邊區域之至少一部分上/上方形成遮光層。形成遮光層目的用於遮蔽置於顯示板周邊區域上之佈線構件及其他構件，以使得不可能自觀察者側視覺識別顯示板中除影像顯示區域以外之任何區域，及增強顯示裝置之設計品質。遮光層可改良顯示器之可見性及外觀。術語「透明基板之周邊區域」係指自除透明基板中心以外之邊緣朝向透明基板中心具有預定寬度之帶狀區域。遮光層形成於整個周邊區域上或周邊區域之至少一部分上。一般而言，遮光層毗連透明基板之周邊邊緣，且係具有預定寬度之帶狀區域。因此，遮光層之外周側通常與其上形成遮光層之透明基板第二主表面之周邊邊緣幾乎相同。術語「遮光層之內周側」係指在具有預定寬度之遮光層區域中更靠近透明基板中心之端側。遮光層形成區域通常係根據透明基板之形狀成型。在透明基板具有矩形形狀之情形中，遮光層外周側之至少一部分係以直線形成。遮光層之內周側可以直線及曲線形成。另外，在遮光層形成區域之一部分中可形成操作狀態之顯示區域以顯示顯示裝置所處狀態或接受來自遠程控制器之操作光(例如紅外輻射)之傳光區域。遮光層係於透明基板第二主表面之周邊區域上/上方形成。較佳地，遮光層形成於自透明基板第二主表面之外周側超過0 mm至低於30 mm範圍內。遮光層可藉由用黑色油墨印刷之方法來形成。印刷方法之實例包括條碼製程、逆塗製程、凹版塗佈製程、模具塗佈製程、輥塗製程及網版印刷製程。在該等製程中，網版印刷製程較佳，此乃因其不僅容許容易且簡單之印刷，且亦容許在多種類型之基板上印刷及根據不同基板大小中之每一者印刷。可無特定限制地使用黑色油墨。作為可用黑色油墨之實例，可提及含有燒製陶瓷或諸如此類之無機油墨及含有諸如顏料或染料等著色材料及有機樹脂之有機油墨。藉由用含有著色顏料之陶瓷印刷形成之遮光層較佳，此乃因其具有高不透光性。遮光層通常以黑色形成，但亦可使用除黑色以外之任何色彩，只要其具有高不透光性即可。或者，遮光層可藉由使具有遮光功能之透明膜及透明基板積層形成。併入無機黑色油墨之陶瓷之實例包括氧化物，例如氧化鉻及氧化鐵；碳化物，例如碳化鉻及碳化鎢、碳黑及雲母。黑色印刷區域6可藉由熔融含有如上文所列舉之陶瓷及二氧化矽之油墨，用經熔融油墨以期望圖案在基板上印刷，然後燒製所印刷油墨來獲得。此一無機油墨需要經受熔融及燒製過程，且其通常用作玻璃專用油墨。有機油墨可為含有黑色染料或顏料及有機樹脂之組合物。有機樹脂之實例包括均聚物，例如環氧樹脂、丙烯酸樹脂、聚對苯二甲酸乙二酯、聚醚碸、聚芳酯、聚碳酸酯、酚樹脂、聚胺基甲酸酯、聚甲基丙烯酸甲酯、聚乙烯基樹脂、聚乙烯丁醛、聚醚醚酮、聚乙烯、聚酯、聚丙烯、聚醯胺及聚醯亞胺；及透明ABS (丙烯腈-丁二烯-苯乙烯)樹脂及包括自該等樹脂之單體中之任一者及可與該等單體共聚合之任何單體形成之共聚物之樹脂。染料或顏料之使用可無特定限制，只要其呈黑色即可。使用有機油墨優於使用無機油墨，此乃因有機油墨之燒製溫度低於無機油墨。此外，使用含有顏料之有機油墨在耐化學性方面較佳。＜光反射率＞本發明積層玻璃含有透明基板、在透明基板之第一主表面上/上方形成之抗反射層及在透明基板第二主表面之周邊區域之至少一部分上/上方形成之遮光層。本發明積層玻璃之光反射率在形成遮光層之區域中較佳為2%或更低，其中光反射率係針對自抗反射層之側入射之光來量測且藉由在透明基板與遮光層之界面移除源自背側反射之效應來測定。積層玻璃之光反射率係指積層玻璃在第一主表面側之最表層表面之光反射率，亦即在積層玻璃不具有防污層之情形中係指抗反射層之光反射率，但在積層玻璃具有防污層之情形中係指抗反射層及防污層之總光反射率。通常作為在僅量測鏡面反射之情形中移除背側反射之效應之方法實施之方法係如下方法：用砂紙或諸如此類韌化透明基板之第二主表面且用黑色標記物或諸如此類進一步降低反射率，由此消除第二主表面之鏡面反射。然而，此一方法在以SCI模式量測之情形中不足，其中亦包括漫反射光。此乃因來自第二主表面之漫射光即使在實施前述處理處理後亦存在。然而，在此一情形中，可藉由以下計算移除背側反射之效應。在設有欲獲得之低反射層之第一主表面之反射率表示為R1時，透明基板之反射率表示為R0且考慮自第一主表面入射，在第二主表面與空氣之間之界面反射出去，然後傳遞穿過第一主表面之光，在對應於其上無遮光層之第二主表面區域中自第一主表面側量測之SCI模式反射率(該反射率表示為Rg)表示為以下方程： Rg = R1 + (1 - R1) × R0 × (1 - R1)。由於R0可藉由在透明基板上藉由使用例如橢圓偏光計進行之折射率量測得出，故量測值Rg及R0成為已知量以容許測定R1。順便提及，實際上，關於在透明基板內側重複往返程之光之項亦存在於前述方程中之第二項之後，但透明基板通常具有約4%之低R0值，且因此該等隨後項小至可忽略不計。由於在本發明中積層玻璃具有2%或更低之低光反射率且黏著劑層具有經適當調節之黏著性，故積層玻璃具有低環境光反射，在遮光層形成區域中令人滿意地免於經受源於黏著劑殘留物或黏著劑所致抗反射層表皮剝落之色彩不均勻，且在其上黏貼有附接黏著劑層之保護膜之區域與其上不黏貼附接黏著劑層之保護膜之區域之間之邊界不引起色彩之色調變化。因此，本發明積層玻璃可確保令人滿意的可見性。光反射率較佳為1.5%或更低，且更佳為1%或更低。在該等情形中，可達成更顯著效應。藉由將積層玻璃之光反射率控制在低至較佳2%或更低，且對用於黏著劑層中之黏著劑之黏著性進行適當調節，可令人滿意地防止積層玻璃經受源於黏著劑殘留物及黏著劑所致抗反射層表皮剝落之色彩不均勻，且在將積層玻璃安裝在顯示裝置上時，不僅可獲得令人滿意的顯示器可見性及顯示器面上之低環境光反射，且亦可獲得優良設計品質及優美外觀。另外，即使在形成防污層作為積層玻璃最表層表面之情形中，只要防污層之厚度足夠小(例如20 nm或更小)，呈積層狀態之防污層對光反射率即無顯著影響。藉由在移除背側反射之效應後將抗反射層及防污層之總光反射率控制在較佳2%或更低，且另外藉由將黏著劑層調節至具有適當黏著性，可令人滿意地防止積層玻璃經由源於黏著劑殘留物及黏著劑所致防污層表皮剝落之色彩不均勻，且在將積層玻璃安裝在顯示裝置上時，不僅可獲得令人滿意的顯示器可見性及顯示器面上之低環境光反射，且亦可獲得優良設計品質及優美外觀。實例在以下實例及比較實例中，將主要闡釋具體使用之材料及程序組合。根據以下程序製備設有防污膜之玻璃基板。首先，採用化學韌化用玻璃Dragontrail (商標，由Asahi Glass Co., Ltd.製造，下文亦縮寫為「DT」)作為透明基板。 (1) 防眩光處理根據以下程序，利用霜化處理使玻璃基板之第一主表面經受防眩光處理。首先，將耐酸性保護膜黏貼至無需防眩光處理之玻璃基板表面側。然後，將所得玻璃基板浸沒至3 wt%氟化氫溶液中3分鐘以移除黏著至玻璃基板表面之污物。此外，經由浸沒至含有15 wt%氟化氫及15 wt%氟化鉀之混合溶液中3分鐘使已移除污物之玻璃基板經受霜化處理，且由此實施對玻璃板第一主表面之霜化處理。藉由浸沒至10%氟化氫溶液中對由此經防眩光處理之玻璃基板進行濁度調節。 (2) 化學韌化處理根據以下程序使經防眩光處理之玻璃基板經受化學韌化處理。首先，使經防眩光處理之玻璃基板經受浸沒至藉由在450℃下加熱熔融之硝酸鉀熔融鹽中2小時，然後自熔融鹽中上升，且進一步經受經1小時逐漸冷卻至室溫，由此獲得化學韌化玻璃。由此獲得之化學韌化玻璃基板具有730 MPa之表面壓應力(CS)及30 μm之應力層深度(DOL)。在上文步驟後，將化學韌化玻璃浸沒至鹼溶液(SUNWASH TL-75，由Lion Specialty Chemicals Co., Ltd.製造) 4小時。 (3) 遮光層之形成其次，根據以下程序在已經歷防眩光處理及化學韌化處理之玻璃基板之第二主表面上實施網版印刷。在玻璃基板第二主表面之外周區域之4個側面上，以具有2 cm寬度之黑色框架形狀實施印刷，以形成遮光層。更具體而言，藉助網版印刷機以5 μm厚度施加黑色油墨(GLSHF，商標名，由Teikoku

Co., Ltd.製造)，然後經由在150℃下保持10分鐘來乾燥，由此形成第一印刷層。在此之後，以5 μm厚度將黑色油墨施加至第一印刷層，然後經由以與上文所提及相同之方式在150℃下保持40分鐘來乾燥，由此形成第二印刷層。因此，形成具有第一及第二印刷層之積層結構之遮光層，且由此獲得在玻璃基板之一個主表面之外周區域上設有遮光層之玻璃基板。 (4) 高折射率層之形成以以下方式在經防眩光處理之玻璃基板之第一主表面側上形成抗反射層。首先，在將含有10 vol%氧氣之氬氣混合物接納至薄膜形成設備中時，藉由使用氧化鈮靶(NBO靶，商標名，由AGC Ceramics Co., Ltd.製造)在壓力為0.3 Pa，頻率為20 kHz，功率密度為3.8 W/cm² 且倒脈衝寬度為5 μsec之條件下實施脈衝式濺鍍，由此在玻璃基板上形成折射率(n)為2.3且厚度為13 nm之由氧化鈮(Nb₂ O₅ )構成之高折射率層(第一層)。在實例4中，以類似於上文之方式在玻璃基板之第一主表面側上形成高折射率層，但是用氮化矽(SiN)代替氧化鈮(Nb₂ O₅ )。更具體而言，由氮化矽構成之高折射率層係以以下方式形成。在將含有50 vol%氮氣之氬氣混合物接納至真空室中時，藉由使用矽靶在壓力為0.3 Pa，頻率為20 kHz，功率密度為3.8 W/cm² 且倒脈衝寬度為5 μsec之條件下實施脈衝式濺鍍，由此形成折射率(n)為2.0且厚度為15 nm之由氮化矽(SiN)構成之高折射率層，該高折射率層全部在其上欲形成高折射率層之玻璃基板表面上。 (5) 低折射率層之形成在將含有40 vol%氧氣之氬氣混合物接納至設備中時，藉由使用矽靶在壓力為0.3 Pa，頻率為20 kHz，功率密度為3.8 W/cm² ，倒脈衝寬度為5 μsec且脈衝寬度為5 μsec之條件下實施脈衝式濺鍍，由此形成折射率(n)為1.45之由氧化矽(SiO₂ )構成之低折射率層。 (6) 抗反射層之形成抗反射層係藉由交替實施高折射率層及低折射率層之形成來形成。 (7) 防污層之形成將防污層以以下方式形成膜。首先，將用於形成含氟有機矽化合物膜之材料作為防污層材料引入加熱器皿中。然後，藉助真空幫浦使加熱器皿經受除氣10小時或更久以自溶液排除溶劑，由此提供用於形成含氟有機矽化合物膜之組合物(下文稱為用於形成防污層之組合物)。在此之後，將含有用於形成防污層之組合物之加熱器皿加熱至270℃，且在達到270℃後，將此情況保持10分鐘直至溫度穩定為止。然後，將設有抗反射層20之玻璃基板置於真空室中，且自連接至含有用於形成防污層之組合物之加熱器皿之噴嘴向玻璃基板之抗反射層上進給用於形成防污層之組合物，由此實施膜形成。在真空室中，在實施膜形成的同時用配備有石英振盪器之監測器組量測膜厚度，且繼續進行直至低折射率層上之含氟有機矽化合物膜之厚度達到4 nm為止。在此之後，自真空室取出玻璃基板，且將其安裝在熱板上，使得含氟有機矽化合物膜之表面面朝上並在空氣中在150℃下熱處理60分鐘。以此方式，獲得具有在抗反射層上形成之防污層之積層玻璃。 (8) 附接黏著劑層之保護膜之黏貼其次，將附接黏著劑層之保護膜置於以前述方式獲得之其上形成防污層之玻璃基板主表面上。此時，黏貼保護膜之黏著劑層，使得其周邊定位於遠離積層玻璃周邊內部2 mm。該積層可能藉由例如預先將保護膜切割至在任一側上較玻璃基板之大小小2 mm之大小來實施。因此，獲得具有保護膜之積層玻璃，其中積層玻璃具有抗反射層、防污層及防眩光層，且另外，將附接黏著劑層之保護膜黏貼至積層玻璃之主表面側，使得保護膜周邊定位於遠離積層玻璃周邊內部2 mm。將在每一實例之說明以及表1中提及用於以下實例及比較實例中之各自具有抗反射層、防污層及防眩光層以及欲黏貼至積層玻璃之具有黏著劑層之保護膜之積層玻璃。表1 實例1 實例2 實例3 實例4 實例5 實例6 比較實例1 比較實例2 基板 DT DT DT DT DT DT DT DT 基板厚度 1.3 mm 2 mm 1.3 mm 1.3 mm 1.3 mm 1.3 mm 1.3 mm 1.3 mm 防眩光處理已實施已實施未實施已實施已實施已實施已實施已實施化學韌化已實施已實施已實施已實施已實施已實施已實施已實施抗反射層 (厚度) Nb₂ O₅ (13nm) Nb₂ O₅ (13nm) Nb₂ O₅ (13nm) SiN (15 nm) Nb₂ O₅ (13nm) Nb₂ O₅ (13nm) Nb₂ O₅ (13nm) Nb₂ O₅ (13nm) SiO₂ (35 nm) SiO₂ (35 nm) SiO₂ (120 nm) SiO₂ (70 nm) SiO₂ (35 nm) SiO₂ (120 nm) SiO₂ (35 nm) SiO₂ (35 nm) Nb₂ O₅ (115 nm) Nb₂ O₅ (115 nm) SiN (17 nm) Nb₂ O₅ (115 nm) Nb₂ O₅ (115 nm) Nb₂ O₅ (115 nm) SiO₂ (90 nm) SiO₂ (90 nm) SiO₂ (105 nm) SiO₂ (90 nm) SiO₂ (90 nm) SiO₂ (90 nm) SiN (15 nm) SiO₂ (50 nm) SiN (120 nm) SiO₂ (80 nm) 防污層 KY-185 KY-185 OPTOOL DSX KY-195 - - KY-185 KY-185 包裝膜 EC-9005ASL UA-3004ASL Y16FAS EC-610B2L EC-9005ASL Y16FAS SAF-010 TTG-3370 基板種類 PET PET 基於聚乙烯基於聚乙烯 PET PET 基於聚丙烯 PET 黏著劑材料基於丙烯酸基於聚胺基甲酸酯基於丙烯酸基於丙烯酸基於丙烯酸基於聚胺基甲酸酯 - 基於丙烯酸長度(t) 2 mm 2 mm 2 mm 2 mm 2 mm 2 mm 2 mm 2 mm 濁度 2% 25% 0% 2% 2% 2% 2% 2% 光反射率 0.30% 0.30% 0.80% 1% 0.30% 0.80% 0.30% 0.30% 黏著性 0.012N/10mm 0.015N/10mm 0.05N/10mm 0.02N/10mm 0.11N/10mm 0.3N/10mm 0.008N/10mm 0.1N/10mm 可見度不均勻性無不均勻無不均勻無不均勻無不均勻無不均勻無不均勻黏貼不均勻邊界兩側色彩不均勻 KY-185：由Shin-Etsu Chemical Co.

Hereinafter, a laminated glass with a protective film is sometimes referred to as "a laminated glass with a protective film". Similarly, a protective film with an adhesive layer is sometimes referred to as a "protective film attached to the adhesive layer". Incidentally, when the protective film-loaded laminated glass 1 explained in each of the first to third embodiments is provided on the image display side (viewer side) of the display panel, it can be used as a protective display The panel of the board. (First Embodiment) The first embodiment of the laminated glass with protective film of the present invention is illustrated in FIG. 1.

The laminated glass 90 includes a transparent substrate 10 having a first major surface and a second major surface, and a first surface of the transparent substrate 10 The anti-reflection layer 20 formed on the main surface and the light shielding layer 70 formed on the peripheral portion of the second main surface of the transparent substrate 10. The protective film 80 to which the adhesive layer is attached is stuck on the laminated glass 90. In the front view of the laminated glass 90, the protective film 80 with the adhesive layer is attached to the laminated glass 90 at the following position: the peripheral edge of the protective film 80 with the adhesive layer is facing the outer peripheral side relative to the inner peripheral side of the light shielding layer 70 It is positioned and positioned toward the inner periphery with respect to the outer periphery of the light shielding layer 70. In addition, the adhesion between the anti-reflection layer 20 formed as the outermost surface of the laminated glass 90 and the adhesive layer 40 is adjusted to fall within the range of 0.01 N/10 mm to 0.3 N/10 mm. By adjusting the adhesiveness between the adhesive layer 40 and the anti-reflection layer 20 to be formed as the main surface of the laminated glass 90 to fall within the range of 0.01 N/10 mm to 0.3 N/10 mm, it is possible to avoid forming the adhesive layer The adhesive remains on at least a part of the outermost surface of the laminated glass 90. By adjusting the adhesiveness between the adhesive layer 40 and the anti-reflection layer 20 to be formed as the main surface of the laminated glass 90 to fall within the range of 0.01 N/10 mm to 0.3 N/10 mm, it is possible to avoid forming the laminated glass At least a part of the material of the anti-reflection layer 20 formed on the outermost surface of 90 is peeled off by the adhesive constituting the adhesive layer. In addition, according to the first embodiment of the laminated glass with a protective film of the present invention, the protective film 80 to which the adhesive layer is attached is adhered to the laminated glass 90 so that the length t is defined as the peripheral edge connecting the outermost surface of the laminated glass 90 When the arbitrary point on the above and the length of the line segment passing through the arbitrary point from the peripheral edge of the outermost surface of the laminated glass to the peripheral edge of the protective film and the point at which the nearest peripheral edge of the protective film intersects the length of the line segment, the The length t is greater than 0 mm and less than 10 mm (see Figure 4). In this embodiment, the light shielding layer 70 formed on the peripheral area of the second main surface of the transparent substrate 10 forms a band-shaped area having a predetermined width from the peripheral edge to the center of the second main surface of the transparent substrate 10. (Second Embodiment) The second embodiment of the laminated glass with protective film of the present invention is illustrated in FIG. 2. The laminated glass 1 carrying the protective film includes a protective film 80 attached with an adhesive layer and a laminated glass 90. The laminated glass 90 includes a transparent substrate 10 having a first major surface and a second major surface, and a first surface of the transparent substrate 10 The anti-reflection layer 20 formed on the main surface and the light shielding layer 70 formed on the peripheral portion of the second main surface of the transparent substrate 10. The laminated glass 90 in the second embodiment of the laminated glass with a protective film of the present invention is further provided with an anti-fouling layer 30 on the main surface of the anti-reflection layer. The protective film 80 to which the adhesive layer is attached is stuck on the laminated glass 90. In the front view of the laminated glass 90, the protective film 80 with the adhesive layer is attached to the laminated glass 90 at the following position: the peripheral edge of the protective film 80 with the adhesive layer is facing the outer peripheral side relative to the inner peripheral side of the light shielding layer 70 It is positioned and positioned toward the inner periphery with respect to the outer periphery of the light shielding layer 70. In addition, the adhesion between the antifouling layer 30 formed as the outermost surface of the laminated glass 90 and the adhesive layer 40 is adjusted to fall within the range of 0.01 N/10 mm to 0.05 N/10 mm. By adjusting the adhesion between the adhesive layer 40 and the antifouling layer 30 to be formed as the main surface of the laminated glass 90 to fall within the range of 0.01 N/10 mm to 0.05 N/10 mm, it is possible to avoid forming the adhesive layer The adhesive remains on at least a part of the outermost surface of the laminated glass 90. By adjusting the adhesiveness between the adhesive layer 40 and the antifouling layer 30 to be formed as the main surface of the laminated glass 90 to fall within the range of 0.01 N/10 mm to 0.05 N/10 mm, it is possible to avoid forming the laminated glass At least a part of the material of the antifouling layer 30 formed on the surface of the outermost layer 90 is peeled off by the adhesive constituting the adhesive layer. In addition, according to the second embodiment of the laminated glass with a protective film of the present invention, the protective film 80 to which the adhesive layer is attached is adhered to the laminated glass 90 so that the length t is defined as the peripheral edge connecting the outermost surface of the laminated glass 90 The length of the vertical line extending from the peripheral edge of the outermost surface of the laminated glass with the anti-fouling layer to the peripheral edge of the protective film through the arbitrary point on the above and the line segment between the point where the nearest peripheral edge of the protective film intersects with this arbitrary point When the length t is greater than 0 mm and less than 10 mm (see Figure 4). (Third Embodiment) The third embodiment of the laminated glass with protective film of the present invention is illustrated in FIG. 3. The third embodiment of the present invention is the following embodiment: in the laminated glass 90 in which the anti-reflection layer 20 is provided as presented in the first embodiment, or in the second embodiment, in which the arrangement is in this order In the laminated glass 90 having the anti-reflection layer 20 and the anti-fouling layer 30, an anti-glare layer 60 is further formed between the first main surface of the transparent substrate 10 and the anti-reflection layer 20. FIG. 3 illustrates an embodiment as follows: in a laminated glass with an anti-fouling layer 30 (the second embodiment), an anti-glare layer 60 is formed between the first main surface of the transparent substrate 10 and the anti-reflection layer 20. However, needless to say, the anti-glare layer 60 may also be formed in a laminated glass without the anti-fouling layer 30 (first embodiment). <Laminated glass> Laminated glass contains at least a transparent substrate having a first main surface and a second main surface, an anti-reflection layer formed on/over the first main surface of the transparent substrate, and an end surface adjacent to the second main surface of the transparent substrate A light-shielding layer formed on/over the peripheral area. The laminated glass may further contain an anti-fouling layer on/above the main surface of the anti-reflection layer. In laminated glass, an anti-glare layer can be formed between the first main surface of the transparent substrate and the anti-reflection layer. <Protective film with adhesive layer> A protective film with an adhesive layer is formed by attaching the adhesive layer to one side of the protective film. In order to protect the display panel installed on the display device during the production process and product transportation, the protective film with the adhesive layer is kept stuck on the outermost surface of the laminated glass, thereby protecting the laminated glass. When using the display device, the protective film with the adhesive layer is peeled off from the laminated glass. By adjusting the adhesiveness of the adhesive constituting the adhesive layer to be attached to the protective film, it is possible to prevent the adhesive constituting the adhesive layer from remaining on at least a part of the outermost surface of the laminated glass. By adjusting the adhesiveness of the adhesive constituting the adhesive layer to be attached to the protective film, it is possible to avoid at least a part of the material constituting the anti-reflective or antifouling layer formed on the surface of the laminated glass. The adhesive peels off. The protective film with the adhesive layer is pasted on the outermost surface of the laminated glass. The protective film with the adhesive layer is stuck on the laminated glass at the following position: When viewing the laminated glass from the front side, the peripheral edge of the protective film is positioned relative to the inner peripheral side of the light-shielding layer toward the outer peripheral side, and relative to the outer peripheral side of the light-shielding layer Position towards the inner circumference. Therefore, when installing laminated glass as a panel of a display device (such as a liquid crystal display (LCD), a plasma display panel (PDP), or an electroluminescence display (ELD)), it is possible to reduce the amount of protection film with an adhesive layer trapped in the device casing. Therefore, when installing laminated glass with a protective film on the display device, the handling properties are enhanced. The term "the peripheral edge of the protective film with the adhesive layer" refers to the edge away from the center of the protective film with the adhesive layer. Generally speaking, the protective film with the adhesive layer has a rectangular shape, and in the case of the rectangular shape, at least a part of the peripheral edge is formed by a straight line. If appropriate, the shape of the protective film with the adhesive layer changes in accordance with the shape of the laminated glass, and therefore at least a part of the peripheral edge can be formed by a curve. In addition, the protective film with the adhesive layer is stuck on the laminated glass at the following position: the length t is defined as connecting any point on the peripheral edge of the outermost surface of the laminated glass and the peripheral edge from the outermost surface of the laminated glass through the arbitrary point When the length of the line segment at the point where the perpendicularly oriented straight line extending to the peripheral edge of the protective film intersects the nearest peripheral edge of the protective film with the adhesive layer, the length t is greater than 0 mm and less than 10 mm. Therefore, it is possible to enhance the handling properties when the laminated glass with the protective film is installed on the display device. The protective film is preferably placed so that its peripheral edge is located directly above a position less than 10 mm away from the peripheral edge of the laminated glass toward the center of the laminated glass. This is because the purpose of protecting laminated glass from impact and the like becomes easy to achieve. In addition, for the purpose of enhancing the convenience of peeling off the protective film with the adhesive layer from the laminated glass, a tongue segment that makes it easy to pick up the edge of the protective film can be provided, or it can be placed on the peripheral edge of the protective film with the adhesive layer. At least a part is provided with an area on which no adhesive layer is formed. Therefore, the protective film with the adhesive layer can be easily peeled off from the laminated glass. Incidentally, the tongue segment set for the purpose of making it easy to peel off can extend beyond the periphery to the extent that it does not affect the handling properties. When the laminated glass with the anti-reflective layer and/or the anti-fouling layer is combined with the protective film with the adhesive layer, manual work can be adopted. However, from the viewpoint of production efficiency, it is preferable that the protective film with the adhesive layer supplied in the form of a rolled-up reel is subjected to laminating with a rubber roller or the like, or the protective film with the adhesive layer is preliminarily protected according to the size of the laminated glass The film is cut into a sheet-shaped protective film, and then subjected to lamination by means of a labeling machine, a seal pasting machine or the like. <Adhesive layer> An adhesive layer is provided on one side of the protective film to form a protective film to which the adhesive layer is attached. The adhesiveness of the adhesive system suitable for the adhesive layer is such that when the protective film with the adhesive layer is peeled off from the laminated glass, the adhesive even resists the adhesive remaining on at least a part of the outermost surface of the laminated glass. The adhesion of the adhesive system suitable for the adhesive layer is such that when the protective film with the adhesive layer is peeled from the laminated glass, the adhesive is inhibited or even peels off the adhesive of at least a part of the material constituting the anti-reflective layer or the anti-fouling layer of the laminated glass. As the adhesive of the adhesive layer specified above, it is preferable to use acrylic-based adhesives, polyurethane-based adhesives, and the like in terms of adhesiveness and peeling properties. As long as the adhesive layer has an adhesiveness of 0.01 N/10 mm or greater, the adhesive can be uniformly adhered to the outermost surface of the laminated glass, and the adhesive is allowed when the protective film attached to the adhesive layer is pasted to the laminated glass The layer is uniformly adhered to the surface of the anti-reflective layer or the surface treatment agent of the anti-fouling layer formed on the outermost surface of the laminated glass. In addition, there is no need to worry about delaminating the protective film from the laminated glass during transportation, etc., and impairing its function as a protective film. As long as the adhesive layer has adhesion of 0.3 N/10 mm or less, the adhesive layer has moderate adhesion, and therefore there is no need to worry about causing defects so that it can be used as a laminated glass when peeling off the protective film attached to the adhesive layer At least a part of the surface treatment agent of the anti-reflection layer formed on the surface of the outermost layer is peeled by the adhesive in an amount greater than required, or the adhesive of the adhesive layer constituting the protective film attached to the adhesive layer remains in the laminated glass. In at least a part of the surface layer, and therefore visibility is reduced and staining occurs. In the case of attaching the protective film of the adhesive layer to the laminated glass forming the anti-reflection layer as the outermost surface, the adhesion between the adhesive layer and the anti-reflection layer is preferably 0.03 N/10 mm to 0.3 N /10 mm, and more preferably 0.05 N/10 mm to 0.15 N/10 mm. By adjusting the adhesiveness to a value within a preferable range, it is possible to inhibit the adhesive from remaining on the anti-reflection layer and prevent the material constituting the anti-reflection layer from being peeled off by the adhesive. In the case of pasting the protective film attached with the adhesive layer to the laminated glass forming the antifouling layer as the outermost surface, the adhesion between the adhesive layer and the antifouling layer is preferably 0.01 N/10 mm to 0.05 N/ 10 mm, and more preferably 0.02 N/10 mm to 0.04 N/10 mm. By adjusting the adhesiveness to a value within a preferable range, it is possible to inhibit the adhesive from remaining on the antifouling layer and prevent the material constituting the antifouling layer from being peeled off by the adhesive. Specifically, the adhesive tends to remain on the surface of the antifouling layer or the material constituting the antifouling layer is easily peeled off by the adhesive. Therefore, it should be understood that the adhesion between the adhesive layer and the anti-fouling layer is adjusted to a value lower than the adhesion between the adhesive layer and the anti-reflective layer. According to the adhesion and peeling ability of the adhesive layer of the protective film attached to the adhesive layer with respect to the anti-reflective layer or the anti-fouling layer, the thickness of the adhesive layer is preferably 3 μm to 50 μm, and more preferably 5 μm to 25 μm. <Protective film> There is no particular limitation on the protective film, as long as it is made of resin and has a film-like form. In addition, the protective film may have a single-layer structure or a multi-layer structure formed by laminating a plurality of layers, the plurality of layers including an antistatic layer, a hard coat layer, and an easy-adhesion layer. In addition, the protective film can be colored in any color to avoid forgetting to peel the protective film with the adhesive layer from the laminated glass. As the protective film, for example, a polyester film such as a polyethylene terephthalate film; a polyolefin film such as a polyethylene film and a polypropylene film; a polyvinyl chloride film or the like can be used. Among these films, the polyester film is better in terms of adhesion to the adhesive layer, durability, and optical characteristics. The thickness of the protective film is not particularly limited, but the thickness is preferably, for example, 5 μm to 100 μm. The thickness in the range of 15 μm to 75 μm is more preferable because the film having a thickness in this range is easy to bend and easy to peel off. On the other hand, a protective film thinner than 5 μm may not provide sufficient protection for the laminated glass, and a protective film thicker than 100 μm may increase the cost. <Transparent substrate> Examples of transparent substrates include commonly used glass plates, such as plates made from soda lime glass, borosilicate glass, aluminosilicate glass and alkali-free glass, and made from inorganic materials with various compositions The inorganic glass plate and transparent resin plate. Examples of materials for the most suitable glass plates include glass materials such as soda lime glass, quartz glass, crystal glass, and sapphire glass. Among these materials, the better one is highly transparent glass with lower iron content and less blue tint. As the material of the transparent resin board, highly transparent resin materials are suitable. Examples of transparent resin plates include polyester resins, such as polycarbonate and polyethylene terephthalate; polyolefin resins, such as polypropylene and polyvinyl chloride; acrylic resins, polyether ether, polyarylate, and triacetate Base cellulose and polymethyl methacrylate. As a transparent substrate, a glass plate is the best because it not only has high transparency, but also has light resistance, heat resistance, low refraction, high flatness accuracy, surface scratch resistance and high mechanical strength. For the purpose of increasing the safety of the glass plate, the mechanical strength can be improved. In order to improve the mechanical strength of the glass plate, the glass plate is subjected to toughening treatment in advance. Examples of toughening treatment include physical toughening by exposing the glass plate to a high-temperature atmosphere and then cooling the glass plate in the air, and by immersing the glass plate in a molten salt containing an alkali metal for storage in the molten salt And the alkali metal (ion) with a large atomic diameter replaces the alkali metal (ion) with a small atomic diameter stored in the outermost surface of the glass plate to achieve chemical toughening. Especially in the case of using a thin glass plate, the glass plate used is preferably a glass plate that has undergone chemical toughening (also referred to as chemically toughened glass). The chemically toughened glass as a transparent substrate preferably satisfies the following conditions. Specifically, preferably, the surface compressive stress (hereinafter abbreviated as CS) of the glass substrate is 400 MPa to 1,200 MPa, and more preferably 700 MPa to 900 MPa. From the viewpoint of actual strength, a CS of 400 MPa or more is sufficient. On the other hand, as long as the glass substrate has a CS of 1,200 MPa or less, the glass substrate can withstand its own compressive stress without the possibility of spontaneous cracking. In the case of using the protective film-loaded laminated glass 1 of the present invention as a display device or the like (cover glass), the CS of the glass substrate is preferably in the range of 700 MPa to 850 MPa. In addition, preferably, the depth of the stress value of the glass substrate (hereinafter referred to as DOL) is 15 μm to 50 μm, and preferably 20 μm to 40 μm. As long as the glass substrate has a DOL of 15 μm or greater, there is no need to worry about the glass substrate being easily scratched and broken. On the other hand, as long as the glass substrate has a DOL of 40 μm or less, the glass substrate can withstand its own compressive stress without the possibility of spontaneous cracking. In the case of using the protective film-loaded laminated glass 1 of the present invention as a display device or the like (cover glass), preferably, the DOL of the glass substrate is in the range of 25 μm to 35 μm. In terms of mechanical strength, sapphire glass is also suitable as a glass substrate. The transparent substrate is generally smooth and has a rectangular shape. If appropriate, the required shape of the transparent substrate can vary according to the shape of the display panel on the display device, the design of the display device, the installation position of the display device, and the like. In other words, the shape of the transparent substrate is not limited to smooth geometry and rectangular shape. For example, the transparent substrate may be a patterned glass with concave and convex on the surface, and it may have a polygonal shape, a circular shape, or an elliptical shape. In addition, the transparent substrate can be not only a flat glass plate but also a glass plate with a curved surface. The term "peripheral edge of the transparent substrate" refers to the end side away from the center of the transparent substrate. Generally speaking, the transparent substrate has a rectangular shape, and in the case of the rectangular shape, at least a part of the peripheral edge is formed by a straight line. If appropriate, the shape of the transparent substrate changes in accordance with the shape of the display panel or the like, and therefore at least a part of the peripheral edge can be formed by a curve. The size of the transparent substrate is appropriately selected according to the size of the display panel or the purpose of using the display device. For example, in the case of being used as a cover glass for a mobile device, the size of the transparent substrate is preferably in the range of 30 mm × 50 mm to 300 mm × 400 mm, and its thickness is in the range of 0.1 mm to 2.5 mm; and In the case of use in a car navigation system, control panel, instrument panel or the like, the size of the transparent substrate is preferably in the range of 50 mm × 100 mm to 2,000 mm × 1,500 mm and its thickness is 0.5 mm to 4 mm Within range. However, the transparent substrate is not particularly limited with respect to its thickness, and the glass plate can be used as the transparent substrate as long as the thickness is 10 mm or less. Regarding mechanical strength, transparency, etc., the thickness of a glass plate used as a transparent substrate is usually about 0.1 mm to 6 mm. Especially in the case of using a glass plate as a transparent substrate in a vehicle-mounted display device, the safety of the glass plate is required, and therefore, from the viewpoint of mechanical strength, its thickness is preferably in the range of 0.2 mm to 2 mm. In the case of using chemically toughened glass for the purpose of efficient chemical toughening treatment, the suitable thickness of the glass substrate is usually 5 mm or less, and preferably 3 mm or less. In the case of using a transparent resin board, the appropriate thickness of the board is 2 mm to 10 mm. The smaller the thickness of the substrate, the more light absorption is reduced, and therefore in terms of improving visibility and transparency, the use of glass plates is better. In addition, it is not necessary that the transparent substrate must have a single-layer structure formed of a single layer, and it may have a multilayer structure formed of multiple layers, such as a laminated glass structure. <Anti-reflective layer> The anti-reflective layer is a layer formed for the purpose of improving the image quality of the display by suppressing the reflection of ambient light, and it is usually formed on/over the first main surface of the transparent substrate. In the case where the anti-glare treatment has been performed on the first main surface of the transparent substrate, the anti-reflection layer 20 is appropriately formed on/over the anti-glare layer 60 produced by the anti-glare treatment. The anti-reflective layer has no specific restrictions on its structure, as long as the structure allows light reflection to be reduced to a certain range. For example, the anti-reflection layer may have a laminated structure including a low refractive index layer and a high refractive index layer. In this context, the high refractive index layer refers to a layer with a refractive index of 1.9 or higher as measured using light with a wavelength of 550 nm, and a low refractive index layer refers to a layer with a refractive index as measured using 550 nm light For example, the layer is 1.6 or lower. Regarding the number of high-refractive index layers and low-refractive index layers in the anti-reflection layer, it may take a form including one high-refractive index layer and one low-refractive index layer, or it may be formed to have more than one high-refractive index layer and low-refractive index layer. structure. In the case of adopting a form including each of a high refractive index layer and a low refractive index layer, it is appropriate that the high refractive index layer and the low refractive index layer are stacked on the main surface of the transparent substrate in the stated order. On the other hand, in the case of forming a structure having one or more high-refractive index layers and low-refractive index layers, it is appropriate to adopt a form including high-refractive-index layers and low-refractive-index layers alternately stacked in the stated order. For enhancing the anti-reflection performance, preferably, the anti-reflection layer is a laminate in which two or more layers are stacked on top of each other. The build-up layer preferably has a total of 2 to 8 layers stacked on top of each other, more preferably a total of 2 to 6 layers stacked on top of each other, and further preferably a total of 2 to 4 layers stacked on top of each other. As mentioned above, the preferred laminate in this article is a laminate in which high refractive index layers and low refractive index layers are alternately stacked, and the total number of high refractive index layers and low refractive index layers is within the range specified above. In addition, other layers can be added within a range that does not affect the optical characteristics. For example, in order to prevent the diffusion of Na from the glass substrate, SiO can be inserted between the glass and the first layer ₂ membrane. The main components of each of the high refractive index layer and the low refractive index layer are not particularly limited, and they can be selected after considering the required degree of anti-reflection and productivity. Examples of the main components in the high refractive index layer include niobium oxide (Nb ₂ O ₅ ), titanium oxide (TiO ₂ ), zirconia (ZrO ₂ ), tantalum oxide (Ta ₂ O ₅₎ , Alumina (Al ₂ O ₃ ) And silicon nitride (SiN). One or more types selected from these materials can preferably be used as the main components in the high refractive index layer. Examples of the main components in the low refractive index layer include silicon oxide (especially silicon dioxide SiO ₂ ), materials containing Si-Sn mixed oxides, materials containing Si-Zr mixed oxides and materials containing Si-Al mixed oxides. One or more types selected from these materials can be preferably used in the low refractive index layer. From the viewpoint of productivity and refractive index, preferably, the high refractive index layer is composed of a species selected from niobium oxide, tantalum oxide, or silicon nitride, and the low refractive index layer is composed of silicon oxide. The anti-reflective layer can be suitably formed by directly forming an inorganic thin layer on the surface on which it is to be formed, by using an etching technique or the like to perform surface treatment or a dry process (e.g., chemical vapor deposition (CVD)) It is formed by a process or a physical vapor deposition (PVD) process, especially a vacuum deposition process or a sputtering process as one of the physical vapor deposition processes. It may also take a form in which an anti-reflection layer and an anti-fouling layer are provided on/above the first main surface of the transparent substrate in the stated order. In this case, when it is intended to make it easy to apply the anti-fouling layer to the anti-reflection layer, the anti-reflection layer may be formed by a wet process. As an example of an anti-reflection layer formed by a wet process, a layer containing low refractive index particles can be mentioned, especially a layer containing low refractive index particles in a matrix component used as a binder. Alternatively, the anti-reflection layer can be provided by using a method of pasting a transparent resin film with anti-reflection function on the transparent substrate. The thickness of the anti-reflection layer is preferably 100 nm to 500 nm. It is advantageous to adjust the thickness of the anti-reflection layer to 100 nm or more, which is why a thickness allows the reflection of ambient light to be effectively reduced. <Antifouling layer> The antifouling layer has at least oil repellency or lipophilicity. The anti-fouling layer can prevent the adhesion of different stains. The stains include not only fingerprint marks but also sweat and dust, making it easy to erase the stains or making the stains inconspicuous, and thus maintain the display The surface is clean. In addition, the antifouling layer can allow fingers to slide smoothly without obstruction during touch panel operation. Regarding the properties of the anti-fouling layer, preferably, by providing an anti-fouling layer on/above the anti-reflective layer, the anti-fouling layer is formed as the outermost surface of the laminated glass. As a method of forming an antifouling layer, for example, a vacuum evaporation method (dry method) in which a fluorine-containing organic compound or the like is evaporated in a vacuum chamber and deposited on the surface of the anti-reflective layer, or a fluorine-containing organic compound or the like can be dissolved A method of preparing a solution with a predetermined concentration in an organic solvent and applying the solution to the surface of the anti-reflection layer (wet method). If appropriate, the dry method may be selected from ion beam assisted deposition, ion plating, sputtering, or plasma CVD, and the wet method may be appropriately selected from spin coating, dip coating, casting, and slit coating. Bu method or spray method. Both the dry method and the wet method can be adopted. Regarding scratch resistance, a dry film forming method is preferably used. The main ingredient in the antifouling layer (antifouling agent) can be appropriately selected from fluorine-containing compounds (fluorine-containing organic compounds) that can impart antifouling, water-repellent, and oil-repellent properties, and the like. Examples of such compounds include fluorine-containing organosilicon compounds and fluorine-containing hydrolyzable compounds. The use of the fluorine-containing organic compound is not particularly limited, as long as it can impart stain resistance, water repellency, and oil repellency. (Fluorine-containing organosilicon compound coating) In the case where an anti-reflective layer is formed on the main surface of the transparent substrate or on the treated surface of the anti-glare layer, it is preferable to provide the anti-fouling layer on the surface of the anti-reflective layer. Fluorine organosilicon compound coating. On the other hand, in the case of using a glass substrate that has undergone surface treatment (such as anti-glare treatment or chemical toughening treatment) and has no anti-reflection layer on the surface as a transparent substrate, it is preferable to directly use this surface treatment. A coating of fluorine-containing organosilicon compound is formed on the surface. As an example of a method of forming a fluorine-containing organosilicon compound coating, the following methods can be mentioned: by using spin coating, dip coating, casting, slit coating, spraying, etc. (For example, perfluoroalkyl group or fluoroalkyl group with perfluoro(polyoxyalkylene) chain) of silane coupling agent, and then subject the coated composition to heat treatment; or vacuum evaporation method in which fluorine-containing organosilicon The compound undergoes vapor deposition and then heat treatment. In order to obtain a high-adhesion fluorine-containing organosilicon compound coating, it is preferable to form the coating by using a vacuum evaporation method. The formation of the fluorine-containing organosilicon compound coating by using a vacuum evaporation method is preferably implemented by using a composition for coating formation containing a fluorine-containing hydrolyzable silicon compound. (Fluorine-containing hydrolyzable silicon compound) When it comes to anti-fouling layer, there is no specific restriction on the fluorine-containing hydrolyzable silicon compound used to form the fluorine-containing organosilicon compound coating, as long as the obtained fluorine-containing organosilicon compound coating has anti-fouling properties (Including water repellency and oil repellency). Specific examples of this fluorine-containing hydrolyzable silicon compound include those each having at least one group selected from the group consisting of perfluoropolyether groups, perfluoroalkylene groups, and perfluoroalkyl groups. The antifouling layer can also be provided by using a method of laminating a transparent resin film with antifouling function. Generally, the thickness of the anti-fouling layer formed on the anti-reflective layer is not particularly limited, but it is preferably 2 nm to 20 nm, more preferably 2 nm to 15 nm, and further preferably 3 to 10 nm. As long as the anti-fouling layer has a thickness of 2 nm or more, the anti-fouling layer can produce a state where the surface of the anti-reflective layer is uniformly covered by the anti-fouling layer, and can easily obtain scratch resistance that can withstand actual use. On the other hand, as long as its thickness is 20 mm or less, the antifouling layer in the laminated state can maintain optical characteristics such as light reflectance and haze in good condition. <Anti-glare layer> When it is intended to impart anti-glare properties to laminated glass, the anti-glare layer can be provided on/above the first main surface of the transparent substrate. In order to impart anti-glare properties, irregularities may be formed in the main surface of the transparent substrate. The main surface with concavities and convexities may be at least one main surface of the transparent substrate, and the concavities and convexities are preferably formed in the first main surface of the transparent substrate. For the method of forming the bumps, generally known methods are applicable. For example, in the case of using a glass substrate as a transparent substrate, a method of applying chemical or physical surface treatment to the main surface of the glass substrate to form unevenness with desired surface roughness, or a wet coating method is applicable. As a specific example of the method of chemically implementing the anti-glare treatment, a method of giving a frosting treatment can be mentioned. The frosting treatment can be performed by, for example, immersing the glass substrate as the material to be treated in a mixed solution containing hydrogen fluoride and ammonium fluoride. As an example of the method of physically implementing the anti-glare treatment, there can be mentioned sandblasting, in which a pressurized air stream loaded with crystalline silicon dioxide powder, silicon carbide powder or the like is delivered to the main surface of the glass substrate; or using it There is a method of rubbing the main surface of the glass substrate with crystalline silicon dioxide powder, silicon carbide powder or the like with a brush dipped in water. Among the treatments mentioned above, frosting treatment is preferred when applying anti-glare treatment to the glass substrate, because it hardly causes the formation of micro cracks in the surface of the processed material, so it hardly causes The mechanical strength is reduced. The main surface of the glass substrate that has undergone the chemical or physical anti-glare treatment as mentioned above is preferably subjected to an etching treatment to fix the surface profile. For the etching treatment, for example, a chemical etching method in which a glass plate is immersed in an aqueous hydrogen fluoride solution as an etching solution can be used. After undergoing the anti-glare treatment and subsequent etching treatment as mentioned above, the main surface of the glass substrate preferably has a surface roughness (root mean square roughness, RMS) of 0.01 μm to 0.5 μm. The surface roughness (RMS) is more preferably 0.01 μm to 0.3 μm, and still more preferably 0.02 μm to 0.2 μm. By adjusting the surface roughness (RMS) to fall within the range specified above, the turbidity value of the glass substrate can be controlled to fall within the range of 1% to 30% after the anti-glare treatment, thereby providing an anti-reflection The transparent substrate 10 of the layer imparts excellent anti-glare properties. Incidentally, the turbidity value is the value specified in JIS K 7136 (2000). Regarding the method of forming the anti-glare layer, the anti-glare layer can be provided by laminating a transparent resin film having an anti-glare function and a transparent substrate. <Light-shielding layer> A light-shielding layer is formed on/over at least a part of the peripheral area of the second main surface of the transparent substrate. The purpose of forming the light-shielding layer is to shield the wiring members and other components placed on the peripheral area of the display panel, so that it is impossible to visually recognize any area of the display panel except the image display area from the observer side, and to enhance the design quality of the display device . The light-shielding layer can improve the visibility and appearance of the display. The term "peripheral area of the transparent substrate" refers to a belt-shaped area with a predetermined width from the edge excluding the center of the transparent substrate toward the center of the transparent substrate. The light shielding layer is formed on the entire peripheral area or on at least a part of the peripheral area. Generally speaking, the light-shielding layer is adjacent to the peripheral edge of the transparent substrate and is a belt-shaped area with a predetermined width. Therefore, the outer peripheral side of the light-shielding layer is usually almost the same as the peripheral edge of the second main surface of the transparent substrate on which the light-shielding layer is formed. The term "inner peripheral side of the light-shielding layer" refers to the end side closer to the center of the transparent substrate in the light-shielding layer area having a predetermined width. The light-shielding layer forming area is usually shaped according to the shape of the transparent substrate. In the case where the transparent substrate has a rectangular shape, at least a part of the outer peripheral side of the light shielding layer is formed in a straight line. The inner peripheral side of the light shielding layer can be formed in a straight line or a curved line. In addition, an operating state display area can be formed in a part of the light shielding layer forming area to display the state of the display device or to receive operating light (for example, infrared radiation) from a remote controller. The light-shielding layer is formed on/above the peripheral area of the second main surface of the transparent substrate. Preferably, the light shielding layer is formed in a range from more than 0 mm to less than 30 mm from the outer peripheral side of the second main surface of the transparent substrate. The light-shielding layer can be formed by printing with black ink. Examples of printing methods include barcode process, reverse coating process, gravure coating process, die coating process, roll coating process, and screen printing process. Among these processes, the screen printing process is better because it not only allows easy and simple printing, but also allows printing on multiple types of substrates and printing according to each of different substrate sizes. Black ink can be used without specific restrictions. As examples of usable black inks, inorganic inks containing fired ceramics or the like and organic inks containing coloring materials such as pigments or dyes and organic resins can be mentioned. The light-shielding layer formed by printing with ceramics containing colored pigments is preferable because of its high opacity. The light-shielding layer is usually formed in black, but any color other than black can also be used as long as it has high opacity. Alternatively, the light-shielding layer can be formed by laminating a transparent film and a transparent substrate with a light-shielding function. Examples of ceramics incorporated into the inorganic black ink include oxides such as chromium oxide and iron oxide; carbides such as chromium carbide and tungsten carbide, carbon black and mica. The black printing area 6 can be obtained by melting an ink containing ceramics and silicon dioxide as listed above, printing the molten ink with a desired pattern on the substrate, and then firing the printed ink. This inorganic ink needs to undergo melting and firing processes, and it is usually used as a special ink for glass. The organic ink may be a composition containing black dyes or pigments and organic resins. Examples of organic resins include homopolymers, such as epoxy resin, acrylic resin, polyethylene terephthalate, polyether ether, polyarylate, polycarbonate, phenol resin, polyurethane, polymethyl Methyl acrylate, polyvinyl resin, polyvinyl butyral, polyetheretherketone, polyethylene, polyester, polypropylene, polyamide and polyimide; and transparent ABS (acrylonitrile-butadiene-benzene Ethylene) resins and resins including copolymers formed from any of the monomers of these resins and any monomers that can be copolymerized with these monomers. The use of dyes or pigments is not particularly limited, as long as they are black. The use of organic inks is better than the use of inorganic inks, because the firing temperature of organic inks is lower than that of inorganic inks. In addition, the use of organic inks containing pigments is better in terms of chemical resistance. <Light reflectance> The laminated glass of the present invention includes a transparent substrate, an anti-reflection layer formed on/over the first main surface of the transparent substrate, and a light shielding layer formed on/over at least a part of the peripheral area of the second main surface of the transparent substrate . The light reflectivity of the laminated glass of the present invention is preferably 2% or lower in the area where the light-shielding layer is formed. The light reflectivity is measured for the light incident from the side of the anti-reflection layer and is measured by the transparent substrate and the light-shielding layer. The interface removal of the layer is determined by the effect of backside reflection. The light reflectivity of laminated glass refers to the light reflectivity of the outermost surface of the laminated glass on the first main surface side, that is, when the laminated glass does not have an anti-fouling layer, it refers to the light reflectivity of the anti-reflective layer. When laminated glass has an anti-fouling layer, it refers to the total light reflectivity of the anti-reflective layer and the anti-fouling layer. The method usually implemented as a method to remove the effect of backside reflection in the case of measuring only specular reflection is the following method: toughen the second main surface of the transparent substrate with sandpaper or the like and use black markers or the like to further reduce the reflection Rate, thereby eliminating the specular reflection of the second main surface. However, this method is insufficient in the case of measuring in SCI mode, which also includes diffuse reflected light. This is because the diffused light from the second main surface exists even after the aforementioned treatment. However, in this case, the effect of backside reflection can be removed by the following calculation. When the reflectance of the first main surface provided with the low-reflection layer to be obtained is expressed as R1, the reflectance of the transparent substrate is expressed as R0 and considering the incident from the first main surface, the interface between the second main surface and the air Reflected out and then transmitted through the first main surface, the SCI mode reflectance measured from the first main surface side in the second main surface area corresponding to the second main surface without a light-shielding layer (the reflectance is expressed as Rg) Expressed as the following equation: Rg = R1 + (1-R1) × R0 × (1-R1). Since R0 can be obtained by measuring the refractive index on a transparent substrate by using, for example, an ellipsometer, the measured values Rg and R0 become known quantities to allow the measurement of R1. Incidentally, in fact, the term about the light that repeats the round trip inside the transparent substrate also exists after the second term in the aforementioned equation, but the transparent substrate usually has a low R0 value of about 4%, and therefore these subsequent terms are as small as Can be ignored. Since the laminated glass in the present invention has a low light reflectivity of 2% or less and the adhesive layer has an appropriately adjusted adhesiveness, the laminated glass has low ambient light reflection and satisfactorily avoids the light-shielding layer formation area. Protection of the non-uniform color of the anti-reflective layer peeling due to adhesive residues or adhesives, and the area where the protective film attached to the adhesive layer is pasted and the adhesive layer that is not attached to it The boundary between the areas of the film does not cause changes in the color tone. Therefore, the laminated glass of the present invention can ensure satisfactory visibility. The light reflectance is preferably 1.5% or lower, and more preferably 1% or lower. In these situations, more significant effects can be achieved. By controlling the light reflectivity of the laminated glass to preferably as low as 2% or less, and by appropriately adjusting the adhesiveness of the adhesive used in the adhesive layer, it is possible to satisfactorily prevent the laminated glass from suffering from The color of the peeling off of the anti-reflective layer caused by the adhesive residue and the adhesive is not uniform, and when the laminated glass is installed on the display device, not only satisfactory display visibility and low ambient light reflection on the display surface can be obtained , And can also obtain excellent design quality and beautiful appearance. In addition, even when the antifouling layer is formed as the surface of the most surface layer of the laminated glass, as long as the thickness of the antifouling layer is small enough (for example, 20 nm or less), the antifouling layer in the laminated state has no significant effect on the light reflectivity. . By removing the effect of backside reflection, the total light reflectivity of the anti-reflection layer and the anti-fouling layer is controlled to be preferably 2% or lower, and by adjusting the adhesive layer to have proper adhesion, Satisfactorily prevent the color unevenness of the laminated glass from peeling off the anti-fouling layer skin caused by the adhesive residue and the adhesive, and when the laminated glass is installed on the display device, not only satisfactory display visibility can be obtained Performance and low ambient light reflection on the display surface, and can also obtain excellent design quality and beautiful appearance. Examples In the following examples and comparative examples, we will mainly explain the specific materials and program combinations used. Prepare a glass substrate with an anti-fouling film according to the following procedure. First, Dragontrail (trademark, manufactured by Asahi Glass Co., Ltd., also abbreviated as "DT" hereinafter) glass for chemical toughening is used as a transparent substrate. (1) Anti-glare treatment According to the following procedure, the first main surface of the glass substrate is subjected to anti-glare treatment by frosting treatment. First, stick the acid-resistant protective film to the surface of the glass substrate that does not require anti-glare treatment. Then, the obtained glass substrate was immersed in a 3 wt% hydrogen fluoride solution for 3 minutes to remove the dirt adhering to the surface of the glass substrate. In addition, the glass substrate from which the contaminants have been removed is subjected to frosting treatment by immersing it in a mixed solution containing 15 wt% hydrogen fluoride and 15 wt% potassium fluoride for 3 minutes, and thereby implements frosting on the first main surface of the glass plate化处理。 Treatment. The turbidity of the anti-glare treated glass substrate is adjusted by immersing in a 10% hydrogen fluoride solution. (2) Chemical toughening treatment The anti-glare treated glass substrate is subjected to chemical toughening treatment according to the following procedure. First, the anti-glare treated glass substrate was subjected to immersion into potassium nitrate molten salt melted by heating at 450°C for 2 hours, then rose from the molten salt, and further subjected to gradually cooling to room temperature for 1 hour, from This obtains chemically toughened glass. The thus obtained chemically toughened glass substrate has a surface compressive stress (CS) of 730 MPa and a depth of stress layer (DOL) of 30 μm. After the above steps, the chemically toughened glass was immersed in an alkali solution (SUNWASH TL-75, manufactured by Lion Specialty Chemicals Co., Ltd.) for 4 hours. (3) Formation of the light-shielding layer Next, screen printing is performed on the second main surface of the glass substrate that has undergone anti-glare treatment and chemical toughening treatment according to the following procedures. On the 4 side surfaces of the outer peripheral area of the second main surface of the glass substrate, printing was performed in the shape of a black frame with a width of 2 cm to form a light-shielding layer. More specifically, black ink (GLSHF, trade name, manufactured by Teikoku Printing Inks Mfg. Co., Ltd.) was applied at a thickness of 5 μm by means of a screen printer, and then dried by keeping it at 150°C for 10 minutes. This forms the first printing layer. After that, the black ink was applied to the first printing layer in a thickness of 5 μm, and then dried by maintaining at 150° C. for 40 minutes in the same manner as mentioned above, thereby forming the second printing layer. Therefore, a light-shielding layer having a laminated structure of the first and second printing layers is formed, and thus a glass substrate with the light-shielding layer provided on the outer peripheral area of one main surface of the glass substrate is obtained. (4) Formation of high refractive index layer An anti-reflection layer is formed on the first main surface side of the anti-glare treated glass substrate in the following manner. First, when the argon gas mixture containing 10 vol% oxygen is received into the thin film forming equipment, by using a niobium oxide target (NBO target, brand name, manufactured by AGC Ceramics Co., Ltd.) at a pressure of 0.3 Pa, The frequency is 20 kHz and the power density is 3.8 W/cm ² And pulse sputtering is performed under the condition of the inverted pulse width of 5 μsec, thereby forming a niobium oxide (Nb oxide) (Nb ₂ O ₅ ) Constitute the high refractive index layer (the first layer). In Example 4, the high refractive index layer was formed on the first main surface side of the glass substrate in a manner similar to the above, but silicon nitride (SiN) was used instead of niobium oxide (Nb ₂ O ₅ ). More specifically, the high refractive index layer made of silicon nitride is formed in the following manner. When the argon mixture containing 50 vol% nitrogen is received into the vacuum chamber, the pressure is 0.3 Pa, the frequency is 20 kHz, and the power density is 3.8 W/cm by using a silicon target. ² And pulse sputtering is performed under the condition of inverted pulse width of 5 μsec, thereby forming a high refractive index layer made of silicon nitride (SiN) with a refractive index (n) of 2.0 and a thickness of 15 nm. The high refractive index The layers are all on the surface of the glass substrate on which the high refractive index layer is to be formed. (5) The formation of the low refractive index layer is when the argon mixture containing 40 vol% oxygen is received into the equipment, by using a silicon target at a pressure of 0.3 Pa, a frequency of 20 kHz, and a power density of 3.8 W/cm ² , The inverted pulse width is 5 μsec and pulse width is 5 μsec under the conditions of pulse sputtering, thereby forming a refractive index (n) of 1.45 silicon oxide (SiO ₂ ) Low refractive index layer. (6) Formation of the anti-reflection layer The anti-reflection layer is formed by alternately forming the high refractive index layer and the low refractive index layer. (7) Formation of antifouling layer The antifouling layer is formed into a film in the following manner. First, the material used to form the fluorine-containing organosilicon compound film is introduced into the heating vessel as the antifouling layer material. Then, the heating vessel is subjected to degassing for 10 hours or more with the aid of a vacuum pump to remove the solvent from the solution, thereby providing a composition for forming a fluorine-containing organosilicon compound film (hereinafter referred to as a composition for forming an antifouling layer)物). After that, the heating vessel containing the composition for forming the antifouling layer was heated to 270°C, and after reaching 270°C, the condition was maintained for 10 minutes until the temperature stabilized. Then, the glass substrate provided with the anti-reflective layer 20 is placed in a vacuum chamber, and the nozzle connected to the heating vessel containing the composition for forming the anti-fouling layer is fed to the anti-reflective layer of the glass substrate for forming The composition of the antifouling layer, thereby implementing film formation. In the vacuum chamber, the film thickness is measured by a monitor group equipped with a quartz oscillator while the film is being formed, and the process is continued until the thickness of the fluorine-containing organosilicon compound film on the low refractive index layer reaches 4 nm. After that, the glass substrate was taken out from the vacuum chamber and mounted on the hot plate so that the surface of the fluorine-containing organosilicon compound film was facing upward and heat-treated in the air at 150°C for 60 minutes. In this way, a laminated glass having an anti-fouling layer formed on the anti-reflection layer is obtained. (8) Sticking of the protective film attached to the adhesive layer Next, the protective film attached to the adhesive layer is placed on the main surface of the glass substrate on which the antifouling layer is formed, obtained in the foregoing manner. At this time, stick the adhesive layer of the protective film so that its periphery is positioned 2 mm away from the inside of the laminated glass periphery. The layering may be implemented by, for example, cutting the protective film in advance to a size that is 2 mm smaller than the size of the glass substrate on either side. Therefore, a laminated glass with a protective film is obtained, wherein the laminated glass has an anti-reflection layer, an anti-fouling layer, and an anti-glare layer, and in addition, the protective film attached with the adhesive layer is pasted to the main surface side of the laminated glass, so that the protective film The periphery is positioned 2 mm away from the inside of the laminated glass periphery.

The laminated glass formed in Example 3 contained an anti-reflective layer and an anti-fouling layer, and was formed in Examples 5 and 6. The laminated glass contains an anti-glare layer and an anti-reflection layer. In these laminated glasses, by adjusting the adhesiveness of the adhesive layer attached to each protective film to fall within a specified range, after peeling off the protective film with the adhesive layer from the laminated glass, before the laminated glass In the view, no unevenness is observed in the light-shielding layer forming area, and there is neither a color tone change at the boundary between the protective film pasted area and the non-protective film pasted area, nor the appearance of a clear boundary. Therefore, a significant improvement in visual appreciation has been achieved. Regarding laminated glass each with an anti-glare layer and an anti-reflection layer (Examples 5 and 6), the adhesiveness of the adhesive layer was adjusted to fall within the range of 0.01 N/10 mm to 0.3 N/10 mm.

The hue of the color at the border changes and there is no obvious border appearance. Therefore, a significant improvement in visual appreciation has been achieved. Regarding laminated glass each with an anti-glare layer, an anti-reflective layer, and an anti-fouling layer (Examples 1, 2 and 4) and a laminated glass with an anti-reflective layer and an anti-fouling layer (Example 3), the adhesiveness of the adhesive layer was adjusted To fall within the range of 0.01 N/10 mm to 0.05 N/10 mm, the content may not be observed in the light-shielding layer formation area in the front view of the laminated glass after peeling off each protective film with the adhesive layer from each laminated glass To be uneven, and in addition, there is neither a change in the color tone at the boundary between the protective film pasted area and the non-protective film pasted area nor the appearance of a clear boundary. Therefore, a significant improvement in visual appreciation has been achieved. The laminated glass formed in Comparative Example 1 was a laminated glass having an anti-glare layer, an anti-reflection layer, and an anti-fouling layer. In this case, the adhesiveness of the adhesive layer was 0.008 N/10 mm, and after the protective film with the adhesive layer was peeled off from the laminated glass, unevenness was observed in the light-shielding layer formation area in the front view of the laminated glass . Therefore, the visual appreciation is degraded. The laminated glass formed in Comparative Example 2 is a laminated glass having an anti-glare layer, an anti-reflection layer, and an anti-fouling layer.

Uniformity, and in addition, there are changes in the hue of the color at the boundary between the protective film pasted area and the non-protective film pasted area and the appearance of the obvious boundary. Therefore, the visual appreciation is degraded. In each laminated glass with a protective film of the present invention, between the area where the protective film is stuck and the area where the protective film is not stuck, even after the protective film is peeled off, there is no visual appreciation change.
