Patent ID: 8721389

Claim:
A manufacturing method of a liquid crystal display, the method comprising: forming a thin film transistor on a first substrate; forming a color filter on a second substrate; forming a mother panel by bonding the first substrate and the second substrate together; injecting liquid crystal between the first substrate and the second substrate; cutting along a boundary of cells of the mother panel to separate a panel; and moving the panel to a grinder that is rotatable and comprises a grinding unit including a grinding surface and a shaft connected to the grinding unit and bringing at least one of edges of a cut surface of the panel to the grinding surface of the grinder to grind the at least one edge, wherein an angle α between a plane perpendicular to a rotational axis of the shaft and the grinding surface and an angle β between the plane perpendicular to the rotational axis of the shaft and an outer surface of the panel perpendicular to the cut surface of the panel and facing the grinding surface of the grinder satisfy 1°≦α≦7° and 10°≦β≦60°, respectively.
