Abstract
In a process for chamfering substrates constituting a liquid crystal display device, it is made possible to prevent a static electricity from generating in a chamfering amount mark used in order to perform a highly accurate chamfering, and improve a chamfering accuracy. There is provided a structure in which a chamfering amount mark formed in an end portion of a 1st substrate is formed so as to be electrically connected to a short wiring , and a connection between the chamfering amount mark and extension wirings which are another conductive wirings is performed, thereby discharging the static electricity to another conductive pattern. Incidentally, there is adopted a structure in which plural mark patterns constituting the chamfering amount mark are intended to be electrically connected by a connecting wiring and, additionally, the connecting wiring is extended to a short wiring side.
