經過染色拉伸製成，其性能決定了偏光片的偏光性能、透過率，同時也是 • 影響偏光片色調和光學耐久性。由於聚乙烯醇製成的偏光膜03易吸水、褪 色而喪失偏光性能，因此需要在其兩邊各使用一層光學均勻性和透明性良 好的保護層膜〇4、〇5來隔絕水分和空氣並保護偏光膜，所述的保護層膜〇4、 〇5—般使用三醋酸纖維素酯（TAC)膜。若採用具有紫外隔離（wcuT) 和防眩（Anti-Glare)功能的保護層膜可製成防紫外型偏光片和防眩型偏光 片。將偏光片貼合在液晶盒4的玻璃面上41便形成了液晶顯示器裝置。 隨著各種液晶顯示裝置，特別是大營幕液晶電視的運用越來越廣泛， 人們對液晶屏提出了越來越高職術要求、視覺美感要求以及成本要求， 例如外觀方面要求架構超薄化、無框化、屏面華麗光亮；在實祕方面要 求抗潮濕和抗在光學雛方面要求提升耻度，減少光通量損失；

保護能力略為不足； 2、 保護層膜的表面抗劃傷能力在涂布了一層抗劃傷涂層（hard c〇at layer)后，理論上能達到最高3H，但由於偏光片是柔性材料，濃度一般為 3〇〇以左右，直接貼附于脆弱的液晶盒的玻璃面上，偏光片沒有足夠的剛性 來實現強度更高的抗劃傷要求； 3、 由於偏光片是由柔性材料組成的，沒有保護液晶盒的功能，當液晶 屏受到外力撞擊或受壓過大時，液晶盒極易損壞； 4、 如圖2所示，為了防止外界光干擾，偏光片的保護層膜〇4的出光 面通常採用麻面處理以達到防眩效果（Anti-Glare)。這種麻面處理具有兩面 性，雖然達到了分散外界干擾光的目的，但同時也對液晶盒發出的光產生 了分散作用’降低了液晶屏的對比度性能。 目前已經有針對顯示器外觀架構和安全性方面改進的“硬屏”技術開 始運用，實現了諸如顯示器表面無框、華麗且抗衝擊等特性。如圖3所示， 這種硬屏09僅僅只是在原有的液晶屏上增加了一層高透硬質材料〇6，如有 機玻璃（亞克力板）、印刷黑框玻璃等，高透硬質材料06的兩個面上需要 貼附上保護層膜07’這種相對獨立添加的硬屏〇9並沒有涉及到由偏光片組 合的液晶屏的基本架構。由於該硬屏〇9與液晶屏之間存在縫隙，液晶屏發 出的偏振光在縫隙處會產生二次折射和内反射，從而直接影響顯示畫面的 質量。作為一種改進，在該硬屏〇9和液晶屏的偏光片〇1之間注入導光樹 脂〇8 ’這種方法解決了採用這種“硬屏”帶來的二次折射的弊病，但卻增 201232063 加了製造工藝難度和成本。 【發明内容】 本發明的目的是提供一種具有透射型偏光功能、亮度增透功能、減反 射功能、抗衝撞擊保護功能、整機架構超薄平面裝飾功能的偏光板。 為實現上述目的，本發明的偏光板膠合在液晶盒的出光面上，其包括

Description of the Invention: [Technical Field] The present invention relates to an assembly of a liquid crystal display, and more particularly to a polarizing plate and a liquid crystal panel using the same. [Prior Art] A polarizer is one of important components of a liquid crystal display device (LCD), and is an optical film having a function of generating polarized light, which is a composite of a plurality of polymer materials. As shown in Fig. 1, the polarizer is attached to both sides of the liquid crystal cell 4, and is referred to as an upper polarizer 〇1 (or a transmissive sheet) and a lower polarizer 02 (or a reflective sheet), respectively, and functions as a backlight. The light of the source is polarized. The liquid crystal display device changes the electrical signal of the liquid crystal layer in the liquid crystal cell to cause the liquid crystal molecules of the liquid crystal layer to be twisted to form an optical channel having a certain twist angle. When the polarized light passes through the optical channel, the conduction and the cutoff amount are controlled. A vivid picture. The current general polarizer architecture is a sandwich architecture, as shown in Fig. ,, consisting of two layers of protective film 04, 05 and an intermediate polarizing film 03. Among them, the polarizing film 〇3 is made of a polyvinyl alcohol material by dyeing and stretching, and its performance determines the polarizing performance and transmittance of the polarizer, and also affects the color tone and optical durability of the polarizer. Since the polarizing film 03 made of polyvinyl alcohol is easy to absorb water and fade, and loses the polarizing property, it is necessary to use a protective film 〇4, 〇5 having good optical uniformity and transparency on both sides to isolate moisture and air and protect it. For the polarizing film, the protective layer film 〇4, 〇5 generally uses a cellulose triacetate (TAC) film. An anti-ultraviolet polarizer and an anti-glare polarizer can be formed by using a protective film having ultraviolet isolation (wcuT) and anti-glare function. A liquid crystal display device is formed by laminating a polarizer on the glass surface 41 of the liquid crystal cell 4. With the increasing use of various liquid crystal display devices, especially large-screen LCD TVs, people have put forward more and more high-level requirements, visual aesthetic requirements and cost requirements for LCD screens. For example, the appearance requires an ultra-thin architecture. No frame, gorgeous screen; in the real secrets, anti-moisture and anti-wet requirements are required to improve the shame and reduce the luminous flux loss; 201232063 With the three-dimensional technology lying on the liquid crystal display device, the LCD screen needs Wei Ling The depth of the image picture is n-party © People ask for the manufacture of the LCD screen. The polarizer is an important part of the LCD screen, especially the performance of the upper polarizer directly to the LCD screen. The existing technical requirements # can not fully meet these technical requirements, the frequency performance is: 1, if the cellulose triacetate film as a protective layer film polarizer, because the protective layer film still has a hazy moisture permeability (permeability) About 300g/m2/day), its protective ability is slightly insufficient under high temperature and high humidity; 2. The surface scratch resistance of the protective film is coated with a hard c〇at layer. After that, it can theoretically reach a maximum of 3H, but since the polarizer is a flexible material, the concentration is generally about 3 ,, which is directly attached to the glass surface of the fragile liquid crystal cell, and the polarizer does not have sufficient rigidity to achieve higher strength. Anti-scratch requirements; 3, because the polarizer is composed of flexible material, there is no function to protect the liquid crystal cell, when the liquid crystal screen is impacted by external force or excessive pressure, the liquid crystal cell is easily damaged; 4, as shown in Figure 2 In order to prevent external light interference, the light-emitting surface of the protective layer film 4 of the polarizer is usually treated with a pockmark to achieve an anti-glare effect (Anti-Glare). This pitting treatment has two-sidedness, and although it achieves the purpose of dispersing external disturbance light, it also disperses the light emitted from the liquid crystal cell, which lowers the contrast performance of the liquid crystal panel. The "hard screen" technology, which has been improved in terms of display architecture and security, has been implemented to achieve features such as frameless, gorgeous and impact resistant surfaces. As shown in Figure 3, this hard screen 09 only adds a layer of high-permeability hard material 〇6 to the original LCD screen, such as plexiglass (acrylic sheet), printed black-frame glass, etc. The relatively independent addition of the hard screen 〇9 to the surface of the protective layer film 07' does not involve the basic structure of the liquid crystal panel combined by the polarizer. Due to the gap between the hard screen 〇9 and the liquid crystal screen, the polarized light emitted by the liquid crystal screen generates secondary refraction and internal reflection at the slit, thereby directly affecting the quality of the display screen. As an improvement, the light-guiding resin 〇8' is injected between the hard screen 9 and the polarizer 〇1 of the liquid crystal panel. This method solves the problem of secondary refraction by using such a "hard screen", but Increase 201232063 adds manufacturing process difficulty and cost. SUMMARY OF THE INVENTION An object of the present invention is to provide a polarizing plate having a transmissive polarizing function, a brightness increasing function, an anti-reflection function, an impact impact protection function, and an ultra-thin planar decorative function of a whole machine structure. In order to achieve the above object, the polarizing plate of the present invention is glued on the light-emitting surface of the liquid crystal cell, and comprises a polyvinyl alcohol film and a protective layer film, and the protective layer film is glued on the light-emitting surface of the polyvinyl alcohol film, wherein the polarizing light The plate further includes a glass substrate glued to the surface of the polyvinyl alcohol film facing the light-emitting surface of the liquid crystal cell as a protective layer on the other side of the polyvinyl alcohol film. Compared with the prior art, the above structure has the following advantages: 1. Since the polarizing plate uses the glass substrate as a component, the ability of the liquid crystal panel to resist external impact and pressure is improved, compared with the "hard screen" in the prior art. The thickness of the liquid crystal screen is effectively reduced while ensuring the hardness; 2. The moisture permeability of the glass substrate is small, and the polyvinyl alcohol film can be effectively protected even in a high temperature and high pressure environment; The layers are very thin and light and have reached a slight intensity. The liquid crystal display device using the polarizing plate can be designed with a frameless structure. 4. The emitted light passes through the hard substrate and the glass substrate acts on the glass substrate to make the liquid crystal display device The horizontal viewing angle is enlarged; 5. Due to the internal reflection of the glass substrate, the depth layering effect of the image is effectively improved, and the conditions for the fuller utilization of the two-dimensional technology are created; 6. The function of the polarizing plate is - The architecture of the body, the overall cost of production is much lower than that of the prior art "hard screen" plus LCD screen. The film is a highly transparent cellulose triacetate film or a polyethylene terephthalate film. The protective film can be used to make various materials for the crystal polarizing layer film. Cellulose triacetate affinity polyethylene terephthalate film 201232063 The glass substrate of the polarizing plate is a flat glass with a concentration of 0.5 mm to 2.5 mm, wherein the preferred concentration is G.7 mm to 1.1 mm. The concentration of the flat sheet has sufficient softness and physical strength to facilitate the bonding of the polarizing plate and the liquid phase. The glass substrate of the polarizing plate is reinforced, and the strengthening treatment is chemical tempering or wind. Cold tempering treatment. The surface pressure stress value of the glass substrate after tempering is greater than 45 〇Mpa ^ The tempering method described above is a glass tempering method well known in the prior art, such as ion exchange method in chemical tempering, etc. The glass substrate can provide higher use intensity for the liquid crystal screen. The vapor-emitting surface of the protective layer film of the polarizing plate has an anti-smoothing bond layer, a scratch-resistant steam bond layer or an anti-static steam layer towel - _上纲.增增The vapor deposition layer has an anti-reflection ship, thereby improving the optical contrast performance of the liquid crystal screen. The anti-scratch layer further improves the scratch resistance of the liquid transfer surface. The anti-static evaporation layer can effectively reduce the static electricity carried on the surface of the polarizing plate. The polarizing plate is printed with a pattern on the glass substrate or the protective film surface, and the pattern of the glass substrate is screen-printed with a resin-based ink or a fine-type ink or a sintered ceramic ink. The pattern on the film is offset. The pattern can be the border of the display screen, trademark, function icon, remote semi-transparent window, etc., or other decorative patterns. It can be used in various designs to meet various manufacturers and consumption. Different appearance requirements of the polarizer: The glue between the layers of the polarizing plate is glued by an optical pressure sensitive adhesive, and the glass substrate is provided with an optical pressure sensitive adhesive layer and a release protective film on the surface of the light emitting surface of the liquid crystal cell. After the polarizing plate is manufactured, the release protective film can be uncovered, which facilitates the transportation and storage of the polarizing plate. When the polarizing plate needs to be glued to the light emitting surface of the liquid crystal cell, the release protective film is exposed to expose the optical pressure sensitive adhesive. Layer, install the light-emitting surface of the positive liquid crystal cell. In summary, the polarizing plate of the present invention integrates various functions such as a polarizing function, a brightness increasing function, an anti-reflection function, an impact impact protection function, and an ultra-thin planar decorative function of the whole machine structure, instead of the flexible bias of the system. This is based on the flexible polarized light #boots to overcome the contrast loss, poor security, no decorative effects, LCD screen architecture must be framed and other defects. 201232063 [Embodiment] The following is a detailed description of the present invention in combination with the specific thief and the thief: As shown in FIGS. 4 to 6, the polarizing plate of the present invention is glued on the light emitting surface 4 of the liquid crystal cell 4, which includes the poly a vinyl alcohol film 1 and a protective layer film 2, the protective layer film 2 is glued on the light-emitting surface 12 of the polyethylene glycol, and its (4) includes Lai, and the surface substrate 3 is glued to the polyvinyl alcohol film 1 On the surface u of the light-emitting surface 41 of the liquid crystal cell 4, it serves as a protective layer for the polyvinyl alcohol film i.
