Description of the Invention: [Technical Field] The present invention relates to an assembly of a liquid crystal display, and more particularly to a hard screen polarizing plate and a liquid crystal panel using the same. [Prior Art] A polarizer is an important component 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, thereby presenting A brightly colored face. The current common upper polarizer architecture is a sandwich architecture, as shown in Figure 1, consisting of two layers of protective layer films 04, 05 and an intermediate layer of polarizing film 〇3. Among them, the polarizing film 〇3 is made of 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 easily absorbed by water and discolored, and the polarizing property is lost, it is necessary to use a protective film 04, 05 having good optical uniformity and transparency on both sides to isolate moisture and air and protect 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 prepared by using a cellulose triacetate film having ultraviolet (UVcUT) and anti-glare functions. 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 are increasingly demanding higher technical requirements, visual reduction requirements, and cost requirements for LCD screens. For example, the appearance requires an ultra-thin architecture. No frame, gorgeous screen; in terms of practicality, 201232112 is required to resist moisture and impact; in optical properties, it is required to improve contrast and reduce luminous flux loss; with the use of three-dimensional technology on liquid crystal display devices, 'LCD screens are also needed It can express the depth level effect of the image picture; on the other hand, the manufacturing cost of the LCD screen is required to be lower and lower. The polarizer is an important part of the LCD screen, especially the performance of the upper polarizer ^ straight to the LCD screen. The prior art polarizer cannot fully meet these technical requirements, and the specific performance is as follows: 1. For example, a polarizer having a cellulose triacetate film as a protective layer film has a certain moisture permeability due to cellulose triacetate. (The permeability is about 3 (8) g / ^ / day), its protective ability is slightly insufficient under high temperature and high humidity; 2 the surface scratch resistance of the protective film is added after a layer of scratch resistant layer (hard(3)泔iayer), the theory Up to 3H can be reached, but since the polarizer is a flexible material, the concentration is generally about 3〇〇//ηι, which is directly attached to the glass surface of the fragile liquid crystal cell. 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 04 of the polarizer is usually treated with hemp acid to achieve a thief effect (Anti. Glarc). This pitting treatment has two-sidedness. Although it achieves the purpose of dispersing external disturbance light, it also disperses the light recorded by the liquid crystal and reduces 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 jian only adds a layer of highly permeable hard material (10) to the original LCD screen, such as plexiglass (acrylic sheet), printed black-framed glass, etc., high-permeability hard material 〇6 The hard-screen G9 to which the protective layer film G7' is attached on both sides does not involve the base 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 a second reading and a ray at the _, thereby directly displaying the quality of the picture. As an improvement, the light guide tree 201232112 曰08 is injected between the hard screen 09 and the polarizer 〇1 of the liquid crystal screen, and the reading method solves the drawback of using the "hard screen, which brings about secondary refraction, but The difficulty and cost of the manufacturing process are increased. [Summary of the Invention] The purpose of this month is to provide a transmissive polarizing function, a brightness enhancement function, an anti-reflection force, an impact impact protection function, and an ultra-thin planar decoration function of the whole machine structure. In order to achieve the above object, the hard-screen polarizing plate of the present invention is glued on the light-emitting surface of the liquid crystal cell, and comprises a layer of protective film laminated with a layer of polyethylene germanium and a protective layer film. In a layer of the polyethylene glycol film facing the light-emitting surface of the liquid crystal cell, wherein the hard-screen polarizing plate further comprises a glass substrate, the glass substrate is glued on the light-emitting surface of the polyethylene film, as a polyethylene The protective layer of the light exit surface of the alcohol film. Compared with the prior art, the above structure has the following advantages: Since the polarizing plate uses a glass substrate as a component, the liquid crystal panel is improved in resistance to external impact and pressure. As compared to the prior art "hard screen", while ensuring the hardness effectively narrow the concentration of the liquid crystal panel; 2, a glass substrate to enhance the ability of the liquid crystal panel surface scratch resistance;
