Therefore, it is important that the liquid crystal panel of the display is cleaned by the τ holding panel. d: The process of the board is made of glass. 'Each step can produce pollutants. The system can be divided into pre-decoration process. The pre-process includes ···ιτ〇 conductive glass cleaning, photoresist coating 4 shadows , _, alignment film process, _ sub-dispersion, frame glue and panel 1329040. Combination and other steps to become an empty liquid crystal cell; post-process aspects include: panel cutting, liquid crystal filling, UV glue sealing, squeegeeing, curing, cleaning and adhering liquid crystal , photoelectric characteristics detection, visual inspection, attaching polarizers, module assembly, and complete the liquid crystal panel production of a display. Although the above liquid crystal panel process is carried out in a clean room, it is inevitably caused by the generation of pollutants. Due to the pollution source of the liquid crystal panel process, it can be mainly divided into: organic, oil, inorganic, and fine particles, organic, The sources of pollution of oils and fats include organic solvents (acetone, alcohol, isopropanol IPA), photoresists, organic resins (UV sealants), liquid crystals, contact oil films, etc., while inorganic sources of pollution include inorganic oxide layers. Metal impurities, which are contaminated by dust, cut glass swarf or granules, are therefore cleaned by appropriate methods for contaminants from different sources. Although the cleaning work has been paid much attention to in the process of liquid crystal panel, it still does not ensure that the panel has no contaminants when attaching the polarizer, especially in the step of squeegee after UV glue and sealing, the excess UV glue will remain. On the surface of the panel, if it is not completely cleaned, as shown in Figure 6, after the curing step, the UV glue contaminant 8 remaining on the panel 7 will be more difficult to remove, so that the contaminant 8 is attached. The polarizer 9 is adhered to the attachment surface of the panel 7 and is not removed. At this time, the polarizer 9 is attached, which is likely to cause bubbles and the like, which affects the display quality, as shown in Fig. 7, and reduces the quality and yield of the process. Moreover, the polarizer is attached to the post-process step, and if the process fails due to the contaminant between the polarizer and the panel, the previous multi-stage process is in vain, which causes the cost of the process to increase. Therefore, the method of the present invention ensures that no impurities are present when the polarizer is attached to the panel. SUMMARY OF THE INVENTION The main object of the present invention is to solve the above problems and to provide a method for keeping no impurities between the polarizer and the panel attachment surface, thereby ensuring the panel when the liquid crystal panel is attached to the polarizer. The attachment surface does not cause the failure of the polarizer attachment, so as to greatly improve the yield of the attached polarizer process, thereby reducing the cost of the process. For the purpose of the foregoing, the present invention prepares two panels with IT0 conductive electrodes, one side of each of the panels is provided with at least one upper film area, and then the second panel is cleaned and cleaned with a cleaning liquid, and then Each of the upper film areas of the cleaned panel is provided with a light-transmissive protective film, and the panel with the protective film is subjected to a process required for a general liquid crystal panel to be filled with liquid crystal and each of the panels is pasted. After attaching the liquid slab of the protective film to the surface of the liquid crystal panel, the protective enamel of the liquid crystal panel is removed, and the area of the protective film is removed from the attachment surface of the liquid crystal panel.
