(II) Prior technology: The conventional manufacturing method of liquid crystal display device is to honing the outer surface of the liquid crystal display panel filled with liquid crystal so that the substrate thickness of the LCD panel after honing is thinner than that of the LCD panel before honing. . In addition, when manufacturing a liquid crystal display device in which liquid crystal is injected by a vacuum method, a pair of substrates are adhered with a sealing material to form a cell. After the sealing material is hardened, the outer surface of the cell is polished before the liquid crystal is injected into the cell. The thickness of the substrate of the cell after honing is thinner than that of the cell before the honing. Alternatively, when manufacturing a liquid crystal display device in which liquid crystal is injected by a dripping method, a sealing material is coated on at least the outer periphery of the substrate on one side, the liquid crystal is dropped on the inside of the sealing material, and then adhered to the substrate on the other side to form a liquid crystal. The outer surface of the liquid crystal cell is polished after the sealing material is hardened, so that the thickness of the substrate of the polished liquid crystal cell is thinner than the thickness of the substrate of the liquid crystal cell before the polishing (for example, refer to Patent Document 1). In addition, the method of honing uniformly honing the flatness and flatness of glass plates required for conventional liquid crystal display devices and the like is characterized by honing a large number of circular plates to deviate their isocenter from the planetary rotation mechanism. The rotation center is installed on the mechanism, and the honing circular plate is rotated eccentrically through the revolution center. In addition to avoiding mutual interference between most of the honing circular plates, it also prevents the unsharpness of the revolution center. Domain. Another kind of glass-7-200414975 plate honing method, characterized in that most honing plates of planetary rotation are made oval or rectangular, and its rotation center is installed on the planet rotation mechanism in accordance with the rotation center of the planet rotation mechanism. In addition to avoiding mutual interference between the majority of the honing plates through the rotation of the orbital center, it also prevents the generation of an area that cannot be honed on the orbital center portion (for example, refer to Patent Document 2). In addition, the honing is performed while adjusting the pressure. After processing, in addition to obtaining high accuracy parallelism and flatness, it also improves the yield rate. Many detectors are set on the lower profile honing disc to detect Measure the pressure applied to the processed object and the displacement caused by the lower honing disc. The corresponding pressure and the distribution of the displacement cause the operators located on the upper honing disc to act, and The grinding wheel that uniformly maintains the pressure applied to the workpiece, or performs a feed-back control on the applied pressure so that the workpiece is uniformly displaced by the applied pressure (for example, refer to Patent Document 3).

Therefore, after the work piece is processed, it is attached to the work piece in a muddy state before the honing. Surface, it must be washed. In addition, if several pieces of processed parts of the LCD panel are processed, a new honing agent must be replaced (because the honing material wears with the honing amount and the number of honing pieces of each piece, the replacement time of the honing agent Not necessarily). The replacement operation of the honing agent must be carried out from the processing groove of the grinding disc to the circulating groove of the honing agent, and the operation time is long.
