Claim 6:
7. A manufacturing method of a shorting bar, comprising:
forming a test signal wiring layer on a substrate;
forming an insulating layer on the substrate on which the test signal wiring layer is formed;
forming a signal lead layer on the substrate on which the insulating layer is formed;
forming a protective layer on the substrate on which the signal lead layer is formed; and
forming a bonding lead layer on the substrate on which the protective layer is formed;
wherein signal leads are made of the transparent conductive material, a coverage region of the protective layer does not overlap with coverage regions of the signal leads, so that a disconnection is between test signal lines and a binding area by washing off the signal leads using acid pickling after a light-on test is completed.
