A grinder wheel for a liquid crystal display device and a method of fabricating a liquid crystal display device using the same are provided. Two grinding surfaces are formed in the grinder wheel used for grinding a substrate so that it is possible to improve grinding characteristics, to increase the life of the grinder wheel, and to reduce grinding time. The method includes cutting the 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, grinding a predetermined region of the liquid crystal display panel using a grinder wheel including two grinding surfaces of a first grinder surface for primary grinding and a second grinder surface for secondary grinding, and unloading the ground liquid crystal display panel.
