In this case, a glass or a glass substrate is used in the liquid crystal panel. The glass is used to prevent misalignment of a signal input pattern and a printed circuit board, and to prevent cracks due to a process shock from occurring. edge is polished.

However, such a polishing process has a process of chamfering the edges and a process of fine polishing. In such a process, a glass having a strong brittleness to the process impact is often damaged.

Further, since the glass is vulnerable to impact even after the polishing operation is finished, it is desirable to increase the frictional resistance to improve the productivity.

Further, when the polishing operation is performed in a state where the upper and lower glasses are bonded to each other, there is a problem that the bonding force is reduced due to the impact and vibration generated during the process, thereby causing defects.
