Abstract:
1. A method of fabricating a liquid crystal display device, the method comprising the steps of: providing array and color filter substrates; performing an array process on the array substrate and a color filter process on the color filter substrate; attaching the array and color filter substrates to each other; cutting the array and color filter substrates attached to each other into a plurality of unit liquid crystal display panels; loading the unit liquid crystal display panel on a grinding table; providing a grinder wheel including a disk-shaped body having a disk-shaped surface, a first grinding part and a second grinding part located on the disk-shaped surface, wherein the second grinding part is an annular grinding ring formed at a peripheral edge of the disk-shaped surface and the first grinding part is an annular grinding ring formed inside and concentric with the second grinding part, and wherein the second grinding part includes a flat second grinding surface and an inclined region at an external edge of the second grinding surface and the first grinding part includes only a flat first grinding surface; primary grinding a predetermined edge region of the liquid crystal display panel using the second grinding surface of the second grinding part; secondarily grinding the predetermined edge region of the liquid crystal display panel using the first grinding surface of the first grinding part, wherein the inclined region forms an inclination angle in order to protect a glass substrate of the unit liquid crystal display panel during grinding, and the inclination angle is 20 to 40° with respect to the longitudinal direction thereof, and wherein the second grinding part and the first grinding part are formed of grindstones having different amounts of roughness; and unloading the ground liquid crystal display panel.
