When called, it is used for LCD, but it can also be used for too 10 15 trims, k ^ Μ 〇 eyepieces,> anti-dazzle in the front of the speeding car, and forward adjustment. Lang Qi, etc. Others are still biased ^ ^ ^ ^ ^ ^ The field display is used by the mirror and the special medical eye 'Xiongsi Da', the conventional display H is used to improve contrast and reduce the glare of the outside world. Polarizer way to solve. Polarizers can be divided into three grades for TN, STN and TFT in LCD applications. Now, with the rise of the LCD panel industry, the market for polarizers has grown significantly. The structure of a traditional polarizer is shown in Figure 1. It is a surface protective layer 10, a CTA (cellulose triacetate) protective layer 20, a PVA layer 30 doped with a polarizing compound, a CTA compliance layer 40, a pressure sensitive adhesive 50, The type layer 60, because the polarizing compound will continue to diffuse out of the pVA layer 30 after the PVA layer 30 is extended and oriented, so the upper and lower CTA protective layers 20 and 40 must be bonded to protect the PVA layer 30. Polarizing compounds, but the strength of the polymer cta protective layers 20 and 40 is not ideal. Polarizers are used for a long time, and there will still be reliability issues. Therefore, the use of polarizers is generally subject to humidity and temperature conditions (80 ° C, 60 ° C / 90% RH), and the cost of the CTA protective layer is high, accounting for 54% of all polarizer materials. 20 1245929 In addition, since the polarizer itself contains many thin layers, the problem of warpage during stacking of the thin film occurs, resulting in a low yield on the production of the polarizer, which makes the high cost of the polarizer, and the polarizer also occurs after production. Dimensional distortion. Furthermore, when the polarizer is used, it is necessary to tear off the release layer and other materials to attach it to the panel ', and this material cannot be recycled and it also consumes the cost of the seat of the material. "The present invention is based on this, it is urgent to think of a flat display element that can integrate a polarizing layer directly with a display substrate and can be applied to a flat display to solve the above problems." After several research experiments, 10 items have been completed. AirPlus inventions. This is 70%. Because the present invention has a novel structure, can provide industrial use, and has practical effects, it has applied for an invention patent in accordance with the law. 15-The purpose of the present invention is to provide a flat display with a polarized enhanced substrate, which can directly form a polarizing layer on the display substrate to strengthen the protection of polarizing compounds and allow the flat display element to pass smoothly. The test has better product reliability and reliability, and avoids the glass separation debris generated by the line when the display panel is broken to cause harm to the person. 'Another object of the present invention is to provide a polarizing enhancement substrate ^: a display element, which can significantly reduce the use of cta protection in traditional polarizers = type, and prevent sharp glass substrates from forming sharp edges when they are broken.卞 f '㈣ can also reduce the problem of scratching the display substrate, and it can also provide a polarizing layer due to the glass substrate-outgassing, anti-20 1245929 display element life. In order to achieve the above objective, the planar display with polarized enhanced substrate of the present invention
