Description of the Invention (Invention Leadership: This invention is related to the manufacture of a liquid crystal display (LCD), especially a wide viewing angle LCD with a raised structure. Invention Backward : Recently, personal data assistant (PDA) and notebook computers have made significant progress. The requirements for portable displays are light weight and low power consumption. Thin film transistor _ liquid crystal display (TFT ton CD) can meet the above requirements. It is required and known that it needs high pixel density and high quality. Generally T ^ -LCD includes a bottom plate formed by a thin film transistor and a pixel electrode, and a top plate with an a-color luminescent sheet. The liquid crystal is filled in the top plate and the bottom plate. = Like Γ, a capacitor is provided, which is used as the switching element of the unit pixel. A gate signal voltage is applied to the switching element of each unit pixel on TF D during operation, and g TF D receives the gate as the number; It will open after pressing, so the data voltage of the image information can be transmitted through the TFTb.

When the data voltage is applied to the TFT, the arrangement of the liquid crystal molecules will be changed, which will change the light characteristics and display the image. Cripples In general, viewing angle and color performance are important issues when designing LCDs. The application of color filters and LCDs is to display the color content of the screen. One of the trends in LCD technology is to improve its viewing angle. However, the paper standard is based on the Chinese National Standard (CNS) _IT line (please first Read the notes on the back and fill out this page): 552449 Μ Β7 V. Description of the invention () The problems with the angle and contrast value still make it unsuitable for large area displays. K. Ohmuro et al. Presented an article on vertical-alignment-mode LCDs (see SID, 97 DIGEST p.845 ~ p.848). In the reference, the application of vertically aligned LCD (VA-LCD) with optical compensation and optimized domain-divided structure has been implemented. This type of vertically aligned LCD has A viewing angle of more than 70 degrees, a fast response time (less than 25 milliseconds), and a contrast value of more than 3,000, however, it still has some disadvantages, such as the need for a complex and expensive mask to form a two-domain structure. The mask rubbing process (mask rubbing process), the mask rubbing process will also cause the electrostatic discharge (ESD) and particles (particles) to communicate with each other, and the mask rubbing process will also cause image afterimages (丨 ^^ # OBJECTS AND SUMMARY OF THE INVENTION The object of the present invention is to provide an LCD with a wide viewing angle.
