INSTRUCTIONS (/) [Technical Field] The present invention relates to a light-shielding method for a flat display device, and more particularly to a light-shielding method suitable for a liquid crystal display device. [Background of the Invention] In recent years, liquid crystal display devices have attracted attention in displays due to their advantages of light weight, small footprint, and thin thickness. The elimination of light leakage at the edge of the panel of the liquid crystal display device has been the focus of the LCD display industry to improve display quality. In the first rain technology towel, most of the liquid crystal display panel has a color filter on the glass plate, and the light shielding plate is attached to the outside of the polarizing plate. However, this method is limited in the width of the light-shielding sheet, so it cannot completely block the visible light on the outer edge of the visible display area, and the light leakage at the edge of the panel module is caused by the conventional light-shielding method. The optical film of the backlight module is printed or attached with a light shielding film. However, due to the latest developments and the increasingly popular novel optical films using new materials (such as DBEF or R) or the new optical film with a kneading surface, printing on optical films is not easy, and manual attachment increases the time and cost. Therefore, it is advantageous for the use and production of liquid crystal display devices. In addition, this method is easy to break the optical film surface and it is necessary to increase the thickness of the panel module and the backlight module and the quality control is not easy. Because of this, the inventor, in the spirit of active invention, thinks about a "shading method for liquid crystal display skirts" that can solve the above problems, and has finally completed the invention of the Jiahui people.
