Abstract: PROBLEM TO BE SOLVED: To provide a polishing wheel for a liquid crystal display device and a method of manufacturing a liquid crystal display device using the same, improving the polishing characteristic and the life of the polishing wheel by forming a double polishing surface on the polishing wheel used in the polishing process for a substrate, and reducing the polishing time. SOLUTION: This method of manufacturing the liquid crystal display device includes: a step of providing a substrate for the liquid crystal display device; a step of performing an array process or a color filter process for the substrate; a step of sticking a substrate where the array process is ended and a substrate where the color filter process is ended to each other; a step of cutting the stuck substrates to a plurality of unit liquid crystal display panels; a step of loading a polishing table with the unit liquid crystal display panel; a step of polishing a predetermined area of the unit liquid crystal display panel using the polishing wheel having a double polishing surface composed of a first polishing surface for the primary polishing and a second polishing surface for the secondary polishing; and a step of unloading the polished unit liquid crystal display panel.

Abstract: A grinder wheel for a liquid crystal display and a grinding method using the same are provided to lengthen the lifespan of the grinder wheel by distributing the concentration of grinding surfaces during grinding. A grinder wheel comprises a cylindrical body(171); a first grinding surface(174A) formed on an upper edge of the cylindrical body; and a second grinding surface(174B) formed inside the first grinding surface. A grinding method of the grinder wheel, includes a step of transferring a unit liquid crystal display panel to a loading unit; a step of moving the unit liquid crystal display panel to a grinding table; a step of grinding a predetermined part of the liquid crystal display panel by using the grinder wheel having the first grinding surface and the second grinding surface; and a step of transferring the liquid crystal display panel to an unloading unit.
