應注意的是，抗菌層的數目在厚度範圍允許下(詳述於後文)，可根據所需使用時效任意增加或減少。It should be noted that the number of antibacterial layers can be increased or decreased arbitrarily according to the required use time when the thickness range allows (detailed later).

在一些實施例中，偏光板100可控制特定光束的偏振方向，在有電場與無電場時使光源產生位相差而在貼附於面板上時呈現明暗的狀態，用以顯示字幕或圖案。In some embodiments, the polarizing plate 100 can control the polarization direction of a specific light beam, causing the light source to generate a phase difference when there is an electric field and when there is no electric field, and present a bright and dark state when attached to a panel to display subtitles or patterns.

在一些實施例中，偏光板100包括一偏光膜，偏光膜的材料可為聚乙烯醇(polyvinyl alcohol，PVA)樹脂膜，其可藉由皂化聚醋酸乙烯樹脂製得。聚醋酸乙烯樹脂的例子包含醋酸乙烯之單聚合物，即聚醋酸乙烯，以及醋酸乙烯之共聚合物和其他能與醋酸乙烯進行共聚合之單體。In some embodiments, the polarizing plate 100 includes a polarizing film, and the material of the polarizing film can be a polyvinyl alcohol (PVA) resin film, which can be made by saponifying polyvinyl acetate resin.

The material of the protective film can be, for example, a thermoplastic resin with excellent transparency, mechanical strength, thermal stability, and moisture barrier properties. Thermoplastic resins may include cellulose resins (e.g., triacetate cellulose (TAC), diacetate cellulose (DAC)), acrylic resins (e.g., poly(methyl methacrylate) ), PMMA), polyester resin (for example, polyethylene terephthalate (PET), polyethylene naphthalate), olefin resin, polycarbonate resin, cycloolefin resin, oriented stretch Oriented-polypropylene (OPP), polyethylene (PE), polypropylene (PP), cyclic olefin polymer (COP), cyclic olefin copolymer (COC) ), or any combination of the above. In addition, the material of the protective film can also be, for example, (meth)acrylic, urethane, acrylic urethane, epoxy, or silicone It is a thermosetting resin or ultraviolet-curing resin. In addition, the above-mentioned protective film can be further subjected to surface treatment, for example, anti-glare treatment, anti-reflection treatment, hard coating treatment, anti-static treatment or anti-fouling treatment. In some In an embodiment, the polarizing plate 100 has a multi-layer structure, including a polyvinyl alcohol film and protective layers attached to both sides of the polyvinyl alcohol film.

在一些實施例中，偏光板100之厚度為77~190μm。In some embodiments, the thickness of the polarizing plate 100 is 77-190 μm.

在一些實施例中，表面保護膜200用於保護偏光板100表面，使偏光板100不易脆裂，不易收縮，也阻隔光學受水氣影響，更可提供不同表面處理的功能。在一些實施例中，表面保護膜200的材料為具有優良之透明性、機械強度、熱穩定性之熱可塑性樹脂材料。可列舉為三醋酸纖維素(triacetate cellulose，TAC)、聚甲基丙烯酸甲酯(polymethylmethacrylate，PMMA)、聚乙烯對苯二甲酸酯(polyethylene terephthalate，PET)、聚丙稀(polypropylene，PP)、環烯烴聚合物(cyclo olefin polymer，COP)、聚碳酸酯(polycarbonate，PC)或上述之任意組合所組成的一族群。In some embodiments, the surface protection film 200 is used to protect the surface of the polarizing plate 100, so that the polarizing plate 100 is not easy to be brittle and shrunk, and it also prevents the optics from being affected by moisture, and can provide different surface treatment functions. In some embodiments, the material of the surface protection film 200 is a thermoplastic resin material with excellent transparency, mechanical strength, and thermal stability. Examples include triacetate cellulose (TAC), polymethylmethacrylate (PMMA), polyethylene terephthalate (PET), polypropylene (PP), ring A group consisting of cyclo olefin polymer (COP), polycarbonate (PC) or any combination of the above.

在一些實施例中，表面保護膜200中可包含抗菌離子作為抗菌層，其中抗菌離子可為鋅離子或銀離子，其中抗菌離子可塗佈於抗菌層表面。藉由鋅離子及/或銀離子與細胞膜、酶蛋白等結合可破壞及固化細胞膜，使得細菌繁殖可藉由干擾細胞的營養攝取而抑制。在一些實施例中，也可在偏光板100的表面上添加抗菌離子，以更延長抗菌時間。In some embodiments, the surface protection film 200 may include antibacterial ions as an antibacterial layer, wherein the antibacterial ions can be zinc ions or silver ions, and the antibacterial ions can be coated on the surface of the antibacterial layer. The combination of zinc ions and/or silver ions with cell membranes, enzyme proteins, etc. can destroy and solidify cell membranes, so that bacterial growth can be inhibited by interfering with the nutrient uptake of cells. In some embodiments, antibacterial ions can also be added to the surface of the polarizing plate 100 to further extend the antibacterial time.

在一些實施例中，可於偏光板捲材上重複貼合多層的連續的抗菌膜而形成一光學捲材，再裁切成特定大小及數量的光學膜10。在一些實施例中，亦可先形成一片狀偏光板100後再貼合複數層抗菌層以形成片狀光學膜10。In some embodiments, multiple layers of continuous antibacterial films can be repeatedly laminated on the polarizing plate coil to form an optical coil, which is then cut into optical films 10 of a specific size and quantity. In some embodiments, a sheet-shaped polarizing plate 100 may be formed first, and then a plurality of antibacterial layers may be laminated to form the sheet-shaped optical film 10.

在一些實施例中，依據實際需求，光學膜10中的複數個疊置抗菌層可具有相同或不同的性質，例如相同或不同的銀離子及/或鋅離子濃度、相同或不同的厚度、相同或不同的材料等等。In some embodiments, according to actual requirements, the plurality of stacked antibacterial layers in the optical film 10 may have the same or different properties, such as the same or different silver ion and/or zinc ion concentration, the same or different thickness, and the same Or different materials and so on.

在一些實施例中，抗菌離子是固定於抗菌層上表面(遠離偏光板100之表面)，因此，設置於最上層的抗菌層210之下的其他抗菌層220及230，在未暴露於空氣中的狀態下可維持原始的抗菌離子濃度。也就是說，即使最上層的抗菌層210已經沒有抗菌效果時，只要將上層的抗菌層210剝除後，使下層的抗菌層220或230暴露於空氣中，就可延長抗菌效果。In some embodiments, the antibacterial ions are fixed on the upper surface of the antibacterial layer (the surface away from the polarizer 100). Therefore, the other antibacterial layers 220 and 230 disposed under the uppermost antibacterial layer 210 are not exposed to the air. The original concentration of antibacterial ions can be maintained in the state. In other words, even if the uppermost antibacterial layer 210 has no antibacterial effect, as long as the upper antibacterial layer 210 is peeled off and the lower antibacterial layer 220 or 230 is exposed to the air, the antibacterial effect can be prolonged.

在一些實施例中，偏光板100與抗菌層之間，及/或複數個疊置的抗菌層之間各包含一黏著層(未繪示)以進行兩層之間的貼合。在一些實施例中，黏著層包含壓敏性黏著劑(pressure sensitive adhesive, PSA)、熱敏性黏著劑、溶劑揮發性黏著劑、及UV可固化黏著劑。在一些實施例中，壓敏性黏著劑包含天然橡膠、合成橡膠、苯乙烯嵌段共聚物、(甲基)丙烯酸系嵌段共聚物、聚乙烯基醚、聚烯烴、及聚(甲基)丙烯酸酯。在一些實施例中，(甲基)丙烯酸(或丙烯酸酯)係指丙烯酸及甲基丙烯酸類二者。在另一些實施例中，壓敏性黏著劑包含(甲基)丙烯酸酯、橡膠、熱塑性彈性體、聚矽氧、胺基甲酸酯、及其組合。在一些實施例中，壓敏性黏著劑係基於(甲基)丙烯酸系壓敏性黏著劑或基於至少一種聚(甲基)丙烯酸酯。In some embodiments, an adhesive layer (not shown) is included between the polarizing plate 100 and the antibacterial layer, and/or between the plurality of stacked antibacterial layers, for bonding between the two layers. In some embodiments, the adhesive layer includes a pressure sensitive adhesive (PSA), a heat sensitive adhesive, a solvent volatile adhesive, and a UV curable adhesive. In some embodiments, the pressure-sensitive adhesive includes natural rubber, synthetic rubber, styrene block copolymer, (meth)acrylic block copolymer, polyvinyl ether, polyolefin, and poly(methyl) Acrylate. In some embodiments, (meth)acrylic (or acrylate) refers to both acrylic and methacrylic. In other embodiments, the pressure-sensitive adhesive includes (meth)acrylate, rubber, thermoplastic elastomer, silicone, urethane, and combinations thereof. In some embodiments, the pressure-sensitive adhesive is based on a (meth)acrylic pressure-sensitive adhesive or based on at least one poly(meth)acrylate.

在一些實施例中，抗菌層210、220及230的厚度相同，且皆為50~100μm，例如55μm或90μm等。在抗菌離子塗佈太薄的情況下，抗菌離子的數量過少，每個抗菌層的抗菌時效過短，則消費者需因為抗菌效果不夠而增加更換偏光板的頻率。此外，使用過薄的抗菌層造成整體光學膜厚度降低，在面板廠組偏貼偏光板時容易發生貼合性不佳問題。在抗菌層太厚的情況下，在研磨光學膜時，容易產生距離較遠的氣泡，因此在過程中容易產生膜層之間分離，而減少抗菌時效。In some embodiments, the thicknesses of the antibacterial layers 210, 220, and 230 are the same, and they are all 50-100 μm, such as 55 μm or 90 μm. When the antibacterial ion coating is too thin, the amount of antibacterial ions is too small, and the antibacterial aging of each antibacterial layer is too short, consumers need to increase the frequency of replacing the polarizing plate because of the insufficient antibacterial effect. In addition, the use of a too thin antibacterial layer causes the overall optical film thickness to be reduced, and poor adhesion problems are likely to occur when the polarizer is attached to the panel factory. When the antibacterial layer is too thick, when the optical film is polished, it is easy to generate air bubbles far away, so it is easy to cause separation between the film layers in the process, which reduces the antibacterial aging.

此外，亦可進一步對上述抗菌層210、220及230實行表面處理，例如，抗眩光處理、抗反射處理、硬塗處理、帶電防止處理或抗污處理等。In addition, the aforementioned antibacterial layers 210, 220, and 230 may be further subjected to surface treatments, such as anti-glare treatment, anti-reflection treatment, hard coating treatment, electrification prevention treatment, or anti-fouling treatment.

在一些實施例中，表面保護膜200(包含複數個抗菌層)的厚度與偏光板100的總厚度不超過1mm。在一些實施例中，由於將各個膜層貼合後，需藉由研磨製程將光學膜的邊緣修為平整的面。藉由限定上述總厚度，可減少研磨時光學膜靠近邊緣處產生氣泡而使得膜層之間有剝離的現象，也可在後續將光學膜設置於顯示面板(未繪示)上時防止超過外觀件(未繪示)的高度。In some embodiments, the thickness of the surface protection film 200 (including a plurality of antibacterial layers) and the total thickness of the polarizing plate 100 do not exceed 1 mm. In some embodiments, after the various film layers are bonded, the edge of the optical film needs to be trimmed to a flat surface through a grinding process. By limiting the above total thickness, it is possible to reduce the occurrence of air bubbles near the edge of the optical film during grinding, which will cause peeling between the film layers, and it can also prevent the optical film from exceeding the appearance when the optical film is subsequently installed on a display panel (not shown) The height of the piece (not shown).

在一些實施例中，表面保護膜200(包含抗菌層210、220及230)的厚度與該偏光板的厚度比例介於0.3~12；光學膜厚度加總可為180μm~1000μm之間；較佳為180μm~650μm之間，且抗菌層個數可為2~16個之間，一般而言，單層抗菌層的時效性大約1~2年，考慮顯示裝置的保固時間大約3~5年的情況下，抗菌層的數目以2~5個較佳，3~5個尤佳。藉此防止光學膜中的各個膜層在研磨期間產生剝離。列舉一個抗菌層與二個以上抗菌層之厚度實例如表1及表2所示：In some embodiments, the ratio of the thickness of the surface protection film 200 (including the antibacterial layers 210, 220, and 230) to the thickness of the polarizing plate is between 0.3 and 12; the total thickness of the optical film can be between 180 μm and 1000 μm; preferably It is between 180μm and 650μm, and the number of antibacterial layers can be between 2-16. Generally speaking, the timeliness of a single antibacterial layer is about 1 to 2 years, and the warranty time of the display device is about 3 to 5 years. In this case, the number of antibacterial layers is preferably 2~5, especially 3~5. This prevents each film layer in the optical film from peeling off during polishing. Examples of the thickness of one antibacterial layer and two or more antibacterial layers are shown in Table 1 and Table 2:

在一些實施例中，離型膜300用於暫時保護偏光板100不受損傷或汙染。在一些實施例中，離型膜300的材料可為聚對苯二甲酸乙二酯(polyethylene terephthalate, PET)、聚對苯二甲酸丁二酯、聚碳酸酯、聚芳酸酯、聚酯樹脂、烯烴樹脂、乙酸纖維素樹脂、丙烯酸樹脂、聚乙烯(polyethylene，PE)、聚丙烯(polypropylene，PP)、環烯烴樹脂或上述之組合。In some embodiments, the release film 300 is used to temporarily protect the polarizing plate 100 from damage or contamination. In some embodiments, the material of the release film 300 may be polyethylene terephthalate (PET), polybutylene terephthalate, polycarbonate, polyarylate, polyester resin , Olefin resin, cellulose acetate resin, acrylic resin, polyethylene (PE), polypropylene (PP), cycloolefin resin or a combination of the above.

在一些實施例中，離型膜的厚度為5~60μm，例如38μm。當厚度超過60μm時，則在光學膜端面研磨時容易使上層膜層之間產生距離較遠的氣泡，使膜層之間黏著力不足而剝離。當厚度低於5μm時，則難以有效保護其內側膜層。In some embodiments, the thickness of the release film is 5-60 μm, such as 38 μm. When the thickness exceeds 60 μm, it is easy to generate air bubbles with a long distance between the upper film layers when the end face of the optical film is polished, and the adhesion between the film layers is insufficient and peels off. When the thickness is less than 5 μm, it is difficult to effectively protect the inner film layer.

一般而言，隨著光學膜的厚度增加，研磨時產生的氣泡距離光學膜邊緣越遠。也就是說，氣泡容易產生在光學膜膜層遠離邊緣處。列舉光學膜（含離型膜）的厚度實例如表3所示： [表3] 偏光板厚度(μm) 抗菌層厚度(μm) 抗菌層個數(個) 離型膜厚度(μm) 光學膜厚度(μm) 邊緣氣泡距離 (μm) 97 55 3 38 300 33 4 355 42 5 410 48 90 3 405 54 4 495 44 5 585 46 Generally speaking, as the thickness of the optical film increases, the air bubbles generated during grinding are farther away from the edge of the optical film. That is to say, air bubbles are easily generated in the optical film layer away from the edge. Examples of the thickness of optical films (including release films) are shown in Table 3: [Table 3] Polarizing plate thickness (μm) Antibacterial layer thickness (μm) Number of antibacterial layers (a) Release film thickness (μm) Optical film thickness (μm) Edge bubble distance (μm) 97 55 3 38 300 33 4 355 42 5 410 48 90 3 405 54 4 495 44 5 585 46

由表2的厚度製造的光學膜，在研磨光學膜端面時產生的氣泡大約距離光學膜30~50μm，其遠遠小於500μm，可確保氣泡在篇貼面板後會落在非顯示區。For the optical film manufactured from the thickness in Table 2, the air bubbles generated when the end face of the optical film is polished are about 30-50μm away from the optical film, which is much smaller than 500μm, which can ensure that the air bubbles will fall in the non-display area after the panel is attached.

當最上層的抗菌層失去抗菌效果時，需剝除最上層的抗菌層。本發明實施例藉由調整光學膜中各膜層之間的黏著層之黏著力以及提握區的特殊設計來提高撕除膜層的便利性與可靠性。When the uppermost antibacterial layer loses its antibacterial effect, the uppermost antibacterial layer needs to be stripped off. The embodiment of the present invention improves the convenience and reliability of tearing off the film layer by adjusting the adhesive force of the adhesive layer between the film layers in the optical film and the special design of the gripping area.

首先，先針對改變光學膜中各膜層之間的黏著層之黏著力來做說明。光學膜中的各個膜層藉由隨著遠離偏光板100而逐漸降低。也就是說，最底層的抗菌層與偏光板之間的黏著力大於任兩個抗菌層之間的黏著力。藉以減少撕錯層的問題，也可防止撕到最底層的膜層而產生功能故障的問題。First of all, we will explain how to change the adhesive force of the adhesive layer between the layers of the optical film. Each film layer in the optical film gradually decreases as it moves away from the polarizing plate 100. In other words, the adhesion between the bottom antibacterial layer and the polarizing plate is greater than the adhesion between any two antibacterial layers. In order to reduce the problem of tearing the wrong layer, it can also prevent the problem of function failure caused by tearing to the bottom layer of the film.

在第1圖的實施例中，偏光板100、抗菌層210、220及230之黏著力的關係可如下式(1)所示： F 100-230＞F 230-220＞F 220-210…(1) In the embodiment of Figure 1, the relationship between the adhesion of the polarizing plate 100 and the antibacterial layers 210, 220 and 230 can be represented by the following formula (1): F 100-230 ＞F 230-220 ＞F 220-210 …( 1)

為達成膜層之間不同的黏著力，可在疊置前先於抗菌層表面進行電漿處理而增加表面的粗糙度，使得黏著層更容易貼合。舉例來說，可在偏光板100的表面或抗菌層230的表面施予較長時間或強度較強的電漿處理，使表面具有較高的粗糙度，進而使兩者的表面產生較大的黏著力；相反地，可在抗菌層210的表面或抗菌層220的表面施予較短時間或強度較弱的電漿處理，使其表面具有較低的粗糙度，進而使兩者的表面產生較小的黏著力。In order to achieve different adhesion between the film layers, plasma treatment can be performed on the surface of the antibacterial layer before stacking to increase the surface roughness, making the adhesive layer easier to adhere. For example, a longer time or stronger plasma treatment can be applied to the surface of the polarizer 100 or the surface of the antibacterial layer 230, so that the surface has a higher roughness, so that the surface of the two has a larger surface. Adhesion; on the contrary, a shorter time or weaker plasma treatment can be applied to the surface of the antibacterial layer 210 or the surface of the antibacterial layer 220, so that the surface has a lower roughness, and then the surface of both Smaller adhesion.

在另一些實施例中，可藉由降低抗菌層表面防汙處理的比例而增加抗菌層表面與黏著層之密著度。舉例來說，在抗菌層210的防汙處理比例為100%時，抗菌層220與230可分別調整為80%與60%，以增加粗糙度而使表面較粗糙，因而增加黏著層黏性。In other embodiments, the adhesion between the surface of the antibacterial layer and the adhesion layer can be increased by reducing the proportion of antifouling treatment on the surface of the antibacterial layer. For example, when the anti-fouling treatment ratio of the anti-bacterial layer 210 is 100%, the anti-bacterial layers 220 and 230 can be adjusted to 80% and 60%, respectively, to increase the roughness and make the surface rougher, thereby increasing the viscosity of the adhesive layer.

在一些實施例中，以抗菌層220與210之間的黏著力為基準，例示出其他膜層之間的黏著力如表4所示：In some embodiments, based on the adhesive force between the antibacterial layers 220 and 210, the adhesive force between other film layers is illustrated as shown in Table 4:

[表4] 黏著力提升對策 實施位置 平均剝離力(N/25mm) 剝離力提升比例(%) 人員撕除次數(次) 抗菌層220和抗菌層210 0.04 0 1~2 抗菌層230和抗菌層220 0.08 100 2~3 偏光板100和抗菌層230 0.12 50 ≧5 [Table 4] Adhesion improvement measures implementation position Average peel force (N/25mm) Lifting ratio of peeling force (%) Personnel removal times (times) Antibacterial layer 220 and antibacterial layer 210 0.04 0 1~2 Antibacterial layer 230 and antibacterial layer 220 0.08 100 2~3 Polarizing plate 100 and antibacterial layer 230 0.12 50 ≧5

在一些實施例中，光學膜中的各個膜層之間的黏著力為0.01N/25mm~0.3N/25mm。當黏著力太小時，則容易產生後續與面板貼合時膜層脫落的問題。當黏著力太大時，則難以撕除個別的抗菌層。In some embodiments, the adhesive force between each film layer in the optical film is 0.01N/25mm~0.3N/25mm. When the adhesive force is too small, the problem of the film layer falling off during subsequent bonding to the panel is likely to occur. When the adhesive force is too large, it is difficult to tear off the individual antibacterial layer.

在一些實施例中，最底層的抗菌層與偏光板之間的黏著力與任兩個抗菌層之間的黏著力之差值為0.04N/25mm~0.29N/25mm。當差值太小時，則容易產生撕錯層的問題(例如撕下多層)。當差值太大時，則底層的抗菌層難以撕除。In some embodiments, the difference between the adhesion between the bottommost antibacterial layer and the polarizing plate and the adhesion between any two antibacterial layers is 0.04N/25mm~0.29N/25mm. When the difference is too small, it is easy to cause the problem of tearing the wrong layer (for example, tearing off multiple layers). When the difference is too large, the antibacterial layer of the bottom layer is difficult to tear off.

在一些實施例中，如表3所示，除了黏著力的量測之外，也可透過人員撕除次數觀察膜層間的撕除的難易程度。舉例來說，撕除次數為5以上，可認定為難以撕除；撕除次數介於2~4之間，可認定為一般；撕除次數為2以下，可認定為易撕除。In some embodiments, as shown in Table 3, in addition to the measurement of the adhesion force, the difficulty of tearing between the film layers can also be observed through the number of tearing by the person. For example, if the number of tearing is more than 5, it can be regarded as difficult to tear; if the number of tearing is between 2 and 4, it can be regarded as normal; if the number of tearing is less than 2, it can be regarded as easy to tear.

接著，針對提握區的設計來做說明。藉由裁切刀具使光學膜中膜層分成本體區與提握區，藉由提握區來剝除最上層的抗菌層，可防止撕錯層的問題，也可避免撕到最底層的膜層而產生功能故障的問題。Next, the design of the grip area will be explained. The film layer in the optical film is divided into the body area and the holding area by the cutting tool. The uppermost antibacterial layer is peeled off by the holding area, which can prevent the problem of tearing the wrong layer and avoid tearing to the bottom layer. The problem of functional failure caused by the film layer.

首先，如第1圖所示，將光學膜10藉由裁切工具在光學膜的一側裁切預定切割處K，可形成如第2圖所示的光學膜。First, as shown in FIG. 1, the optical film 10 is cut at a predetermined cutting position K on one side of the optical film with a cutting tool to form the optical film as shown in FIG. 2.

在一些實施例中，偏光板捲材可藉由刀模沖壓、雷射裁切、或圓刀裁切等進行裁切。在一些實施例中，可在裁切單元中設定好預切割的深度及位置，以利於同時裁切所有的預定切割處K。In some embodiments, the polarizing plate coil can be cut by die punching, laser cutting, or round knife cutting. In some embodiments, the depth and position of the pre-cutting can be set in the cutting unit to facilitate cutting all the predetermined cutting locations K at the same time.

在第2圖中，光學膜10的一側被切割成三個提握區，分別為第一提握區10G1、第二提握區10G2、及第三提握區10G3。在此，被切割處形成狹縫S。此外，未被切割的區域為本體區10B。In Figure 2, one side of the optical film 10 is cut into three holding areas, which are a first holding area 10G1, a second holding area 10G2, and a third holding area 10G3. Here, a slit S is formed at the cut portion. In addition, the uncut area is the body area 10B.

在此實施例中，第一提握區10G1、第二提握區10G2、及第三提握區10G3沿著本體區10B的一側相鄰設置(在X方向上相鄰設置)。在此實施例中，第一提握區10G1相鄰兩側的狹縫S11與S12具有相同的高度。可以從第2圖中看出，第一提握區10G1相鄰兩側的狹縫S11與S12從光學膜10底部穿過表面保護膜200直到露出第一抗菌層210的底表面，因此第一提握區10G1僅與第一抗菌層210連接，並且可於後續剝除第一抗菌層210。In this embodiment, the first holding area 10G1, the second holding area 10G2, and the third holding area 10G3 are adjacently arranged along one side of the body area 10B (arranged adjacently in the X direction). In this embodiment, the slits S11 and S12 on the two adjacent sides of the first grip area 10G1 have the same height. It can be seen from Figure 2 that the slits S11 and S12 on the two adjacent sides of the first holding area 10G1 pass through the surface protection film 200 from the bottom of the optical film 10 until the bottom surface of the first antibacterial layer 210 is exposed. The grip area 10G1 is only connected to the first antibacterial layer 210, and the first antibacterial layer 210 can be peeled off later.

類似地，第二提握區10G2相鄰兩側的狹縫S21與S22(未繪示於第2圖中，可參照第4圖)也具有相同的高度，然而，第二提握區10G2相鄰兩側的狹縫S21與S22從光學膜10底部穿過表面保護膜200直到露出第二抗菌層220的底表面，因此第二提握區10G2藉由第二抗菌層220與第一抗菌層210連接，並且可於後續剝除第二抗菌層220。Similarly, the slits S21 and S22 (not shown in FIG. 2 and refer to FIG. 4) on both sides adjacent to the second grip area 10G2 also have the same height. However, the second grip area 10G2 is opposite to each other. The slits S21 and S22 on the adjacent two sides pass through the surface protection film 200 from the bottom of the optical film 10 until the bottom surface of the second antibacterial layer 220 is exposed. Therefore, the second grip area 10G2 is supported by the second antibacterial layer 220 and the first antibacterial layer. 210 is connected, and the second antibacterial layer 220 can be peeled off later.

類似地，第三提握區10G3相鄰兩側的狹縫S31與S32(未繪示於第2圖中，可參照第4圖)也具有相同的高度，然而，第三提握區10G3相鄰兩側的狹縫S31與S32光學膜10底部穿過離型膜300與偏光板100直到露出第三抗菌層230的底表面，因此第三提握區10G3藉由第三抗菌層230及第二抗菌層220與第一抗菌層210連接，並且可於後續剝除第三抗菌層230。Similarly, the slits S31 and S32 (not shown in Figure 2 and refer to Figure 4) on both sides adjacent to the third grip area 10G3 also have the same height. However, the third grip area 10G3 is relatively The bottoms of the slits S31 and S32 on both sides of the optical film 10 pass through the release film 300 and the polarizing plate 100 until the bottom surface of the third antibacterial layer 230 is exposed. Therefore, the third grip area 10G3 is supported by the third antibacterial layer 230 and the first antibacterial layer. The second antibacterial layer 220 is connected to the first antibacterial layer 210, and the third antibacterial layer 230 can be peeled off later.

由上可知，在第三方向(方向z)上，狹縫S11與S12高於狹縫S21與S22，且狹縫S21與S22也高於S31與S32。此外，狹縫S11、S21與S31彼此不重疊。It can be seen from the above that in the third direction (direction z), the slits S11 and S12 are higher than the slits S21 and S22, and the slits S21 and S22 are also higher than S31 and S32. In addition, the slits S11, S21, and S31 do not overlap with each other.

接著，請參照第3圖，第3圖是根據本發明的一些實施例，繪示出光學膜沿著第2圖的剖線A-A’的剖面圖。Next, please refer to FIG. 3. FIG. 3 is a cross-sectional view of the optical film along the section line A-A' of FIG. 2 according to some embodiments of the present invention.

在第3圖的實施例中，狹縫S11區隔第一提握區10G1與第二提握區10G2，狹縫S21區隔第二提握區10G2與第三提握區10G3，狹縫S31區隔第三提握區10G3與本體區10B。In the embodiment of Figure 3, the slit S11 separates the first grip area 10G1 and the second grip area 10G2, the slit S21 separates the second grip area 10G2 and the third grip area 10G3, and the slit S31 Separate the third grip area 10G3 from the body area 10B.

在此實施例中，第一提握區10G1、第二提握區10G2、及第三提握區10G3分別具有寬度W1、W2及W3。在一些實施例中寬度W1、W2及W3大於或等於1mm。當小於1mm時，提握區中的下方膜層（例如偏光板100或離型膜300）容易脫落而造成沾黏的問題。In this embodiment, the first grip area 10G1, the second grip area 10G2, and the third grip area 10G3 have widths W1, W2, and W3, respectively. In some embodiments, the widths W1, W2, and W3 are greater than or equal to 1 mm. When it is less than 1 mm, the lower film layer (such as the polarizing plate 100 or the release film 300) in the grip area is likely to fall off, causing sticking problems.

接著，第4~7圖是根據本發明的一些實施例，分別繪示出第2圖中的光學膜的各個膜層的上視圖。Next, FIGS. 4-7 are top views of each layer of the optical film in FIG. 2 according to some embodiments of the present invention.

請先參照第4圖，其為最上層的抗菌層210的上視圖。在第4圖中，第一提握區10G1位於抗菌層210一側(+Y方向側)的角落，並且後續可藉由第一提握區10G1剝除抗菌層210。此外，在第4圖中，第一提握區10G1與本體區10B相連接。最上層的抗菌層210未被裁切刀具切割，因此僅有一個區域。Please refer to FIG. 4 first, which is a top view of the uppermost antibacterial layer 210. In Figure 4, the first grip area 10G1 is located at the corner on the side of the antibacterial layer 210 (+Y direction side), and the antibacterial layer 210 can be peeled off by the first grip area 10G1 later. In addition, in Figure 4, the first grip area 10G1 is connected to the body area 10B. The uppermost antibacterial layer 210 is not cut by the cutting tool, so there is only one area.

接著參照第5圖，其為抗菌層220的上視圖。在第5圖中，第一提握區10G1也位於抗菌層220一側的角落，而第二提握區10G2位於第一提握區10G1的-x方向側。在第5圖中，第一提握區10G1藉由狹縫S11與S12與本體區10B間隔，而第二提握區10G2與本體區10B相連接。此外，後續可藉由第二提握區10G2剝除抗菌層220。經裁切刀具切割後的第二層抗菌層220藉由狹縫S11與S12被分成兩個區域。Next, refer to FIG. 5, which is a top view of the antibacterial layer 220. In Figure 5, the first grip area 10G1 is also located at the corner on the side of the antibacterial layer 220, and the second grip area 10G2 is located on the -x direction side of the first grip area 10G1. In FIG. 5, the first grip area 10G1 is separated from the main body area 10B by slits S11 and S12, and the second grip area 10G2 is connected to the main body area 10B. In addition, the antibacterial layer 220 can be peeled off by the second holding area 10G2 later. The second antibacterial layer 220 cut by the cutting tool is divided into two regions by slits S11 and S12.

接著參照第6圖，其為抗菌層230的上視圖。在第6圖中，第一提握區10G1也位於抗菌層220一側的角落，第二提握區10G2也位於第一提握區10G1的-x方向側，而第三提握區10G3位於第二提握區10G2的-X方向側。在第6圖中，第一提握區10G1藉由狹縫S11與S12與本體區10B間隔，第二提握區10G2藉由狹縫S21與S22與本體區10B間隔，而第三提握區10G3與本體區10B相連接。此外，後續可藉由第三提握區10G3剝除抗菌層230。經裁切刀具切割後的第三層抗菌層230藉由狹縫S11與S12、S21與S22被分成三個區域。Next, refer to FIG. 6, which is a top view of the antibacterial layer 230. In Figure 6, the first grip area 10G1 is also located at the corner on the side of the antibacterial layer 220, the second grip area 10G2 is also located on the -x direction side of the first grip area 10G1, and the third grip area 10G3 is located The -X direction side of the second grip area 10G2. In Figure 6, the first grip area 10G1 is separated from the body area 10B by slits S11 and S12, the second grip area 10G2 is separated from the body area 10B by slits S21 and S22, and the third grip area 10G3 is connected to the body area 10B. In addition, the antibacterial layer 230 can be peeled off by the third holding area 10G3 later. The third antibacterial layer 230 cut by the cutting tool is divided into three regions by slits S11 and S12, S21 and S22.

接著參照第7圖，其為偏光板100的上視圖。類似於第6圖，在第7圖中，第三提握區10G3藉由狹縫S31與S32與本體區10B間隔。此外，在偏光板100上的不同的提握區後續用以剝除上方不同層的抗菌層。經裁切刀具切割後的第四層偏光板100藉由狹縫S11與S12、S21與S22、S31與S32被分成四個區域。Next, refer to FIG. 7, which is a top view of the polarizing plate 100. Similar to FIG. 6, in FIG. 7, the third holding area 10G3 is separated from the main body area 10B by slits S31 and S32. In addition, the different holding areas on the polarizing plate 100 are subsequently used to peel off different layers of the antibacterial layer above. The fourth layer of polarizing plate 100 cut by the cutting tool is divided into four regions by slits S11 and S12, S21 and S22, S31 and S32.

由上可知，區域的數目與抗菌層的數目相關聯。在一些實施例中，偏光板的區域數目與任一個抗菌層的區域數目相減之差值大於或等於1，藉以利用不同的提握區剝除不同的抗菌層。舉例來說，第7圖中的偏光板100具有四個區域，而第4~6圖中的抗菌層210、220與230分別具有一、二、三個區域，因此偏光板100與抗菌層210、220與230的區域數目的差值分別為3、2與1。It can be seen from the above that the number of regions is related to the number of antibacterial layers. In some embodiments, the difference between the number of regions of the polarizing plate and the number of regions of any antibacterial layer is greater than or equal to 1, so that different gripping areas can be used to peel off different antibacterial layers. For example, the polarizing plate 100 in Figure 7 has four areas, and the antibacterial layers 210, 220, and 230 in Figures 4 to 6 have one, two, and three areas, respectively. Therefore, the polarizing plate 100 and the antibacterial layer 210 The difference between the number of regions of, 220 and 230 is 3, 2 and 1, respectively.

應注意的是，離型膜300之上視圖(未繪示)類似於偏光板100之上視圖，在此不再贅述。It should be noted that the top view (not shown) of the release film 300 is similar to the top view of the polarizer 100, and will not be repeated here.

接著，第8圖是根據本發明的一些實施例，繪示出光學膜在移除離型膜後且在設置於顯示面板前的立體圖，而第9圖是根據本發明的一些實施例，繪示出顯示裝置的立體圖。Next, FIG. 8 is a perspective view of the optical film after the release film is removed and in front of the display panel according to some embodiments of the present invention, and FIG. 9 is a perspective view of some embodiments according to the present invention.

首先，顯示裝置1000包含顯示面板500，其包括顯示區510與邊框區520。此外，將離型膜300從光學膜10中剝除後，可得第8圖中的光學膜10’。接著，將第8圖中光學膜10’的提握區對準顯示面板500的邊框區520，並將光學膜10’與顯示面板500貼合，可得到如第9圖所示的顯示裝置1000。在第9圖中，顯示面板500中未被光學膜10’貼合的部分皆位於邊框區520，因此並不影響顯示效果。應注意的是，為凸顯特徵，顯示裝置1000中的各個部件尺寸也未按照比例繪示。First, the display device 1000 includes a display panel 500, which includes a display area 510 and a frame area 520. In addition, after the release film 300 is peeled off from the optical film 10, the optical film 10' in Fig. 8 can be obtained. Next, align the holding area of the optical film 10' in Figure 8 with the frame area 520 of the display panel 500, and attach the optical film 10' to the display panel 500 to obtain the display device 1000 as shown in Figure 9 . In Figure 9, the parts of the display panel 500 that are not bonded to the optical film 10' are all located in the frame area 520, so the display effect is not affected. It should be noted that, in order to highlight features, the sizes of the various components in the display device 1000 are also not drawn to scale.

在一些較佳實施例中，顯示面板500為醫用顯示面板，因此對於抗菌效果上有較高的要求。在一些實施例中，顯示裝置1000為臨床監測用顯示器、手術用顯示器、診斷用顯示器、超音波用顯示器、牙科用顯示器等等。In some preferred embodiments, the display panel 500 is a medical display panel, so there is a higher requirement for the antibacterial effect. In some embodiments, the display device 1000 is a display for clinical monitoring, a display for surgery, a display for diagnosis, a display for ultrasound, a display for dentistry, or the like.

接著，第10圖是根據本發明的一些實施例，繪示出顯示裝置沿著第9圖的剖線B-B’的剖面圖，而第11圖是根據本發明的一些實施例，繪示出顯示裝置沿著第9圖的剖線C-C’的剖面圖。Next, FIG. 10 is a cross-sectional view of the display device along the line BB' of FIG. 9 according to some embodiments of the present invention, and FIG. 11 is a cross-sectional view of some embodiments of the present invention. A cross-sectional view of the display device along the line CC' in FIG. 9 is shown.

在第10圖中，顯示面板500位於狹縫S11、S21、及S31的底表面。此外，在第10圖中的光學膜10’皆位於邊框區520，特別是提握區10G1、10G2與10G3也位於邊框區520，因此即使偏光板100有狹縫存在，也不會影響顯示效果。In FIG. 10, the display panel 500 is located on the bottom surface of the slits S11, S21, and S31. In addition, the optical film 10' in Figure 10 is all located in the frame area 520, especially the grip areas 10G1, 10G2, and 10G3 are also located in the frame area 520, so even if the polarizer 100 has slits, it will not affect the display effect. .

在第11圖中，光學膜10’位於顯示區510及部分的邊框區520。應注意的是，狹縫S12仍位於邊框區520，因此不會影響顯示效果。In Figure 11, the optical film 10' is located in the display area 510 and part of the frame area 520. It should be noted that the slit S12 is still located in the frame area 520, so the display effect will not be affected.

在其他實施例中，顯示裝置500更包含外觀件600，其沿著邊框區520設置，如第12圖所示。在第12圖中，外觀件600的邊緣與顯示面板500的邊緣齊平。In other embodiments, the display device 500 further includes an appearance member 600 disposed along the frame area 520, as shown in FIG. 12.

在一些實施例中，在方向z上，外觀件600的厚度(或高度)大於光學膜10’的厚度(或高度)，以防止光學膜10’突出於外觀件600的表面。In some embodiments, in the direction z, the thickness (or height) of the appearance member 600 is greater than the thickness (or height) of the optical film 10' to prevent the optical film 10' from protruding from the surface of the appearance member 600.

在一些實施例中，在方向y上，一側的邊框區520中之光學膜10’的寬度L小於或等於外觀件600至邊框區520的距離D。也就是說，在方向y上，光學膜10’具有狹縫S12的一側與外觀件600具有一間距或齊平。藉以，防止光學膜10’跨至外觀件600的頂表面上，進而防止光學膜10’不平坦而容易造成膜層之間的剝離。In some embodiments, in the direction y, the width L of the optical film 10' in the frame area 520 on one side is less than or equal to the distance D from the appearance member 600 to the frame area 520. That is, in the direction y, the side of the optical film 10' with the slit S12 is spaced or flush with the appearance member 600. In this way, the optical film 10' is prevented from straddling the top surface of the appearance member 600, thereby preventing the optical film 10' from being uneven and easily causing peeling between the film layers.

在一些實施例中，在方向y上，一側的邊框區520中光學膜10’的寬度L大於或等於1mm。當小於1mm時容易產生難以剝除抗菌層的問題。In some embodiments, in the direction y, the width L of the optical film 10' in the frame area 520 on one side is greater than or equal to 1 mm. When it is less than 1 mm, it is easy to cause the problem that it is difficult to peel off the antibacterial layer.

在一些實施例中，外觀件600的材料可包含玻璃、塑膠、金屬、不鏽鋼等，可列舉如鋁合金。在一些實施例中，外觀件600可列舉如邊框等等。In some embodiments, the material of the appearance member 600 may include glass, plastic, metal, stainless steel, etc., such as aluminum alloy. In some embodiments, the appearance member 600 may be a frame or the like.
