PROBLEM TO BE SOLVED: To prevent electrostatic buildup at a mark for a chamfering amount for highly accurate chamfering, and improve the accuracy of the chamfering, in a process of chamfering a substrate for composing a liquid crystal display device. SOLUTION: A mark for a chamfering amount 7 to be formed at the end part of a 1st substrate 1 is formed so as to be electrically connected with the wiring 10 for shorting, and the mark 7 is connected with extending wiring 9 of other conductive wiring, and is structured to discharge static electricity to other conductive pattern. Moreover, the mark is structured so that plural mark patterns 8b composing the mark for the chamfering amount 7 are electrically connected with each other via connection wiring 8a, and the connection wiring 8a is further extended toward the short-circuit wiring 10.
