To provide a defect correction method, decreasing a resistance value of a correcting part.
According to this defect correction method, a correction layer 5 containing metal material is formed to cover a breaking of wire defect part 3 of a wire 2 formed on a glass substrate 1 and part of a normal part of the wire 2 existing at both ends thereof, laser light is applied to each of two overlapping regions of the correction layer 5 and the wire 2, thereby welding the correction layer 5 and the wire 2 to each other in the respective regions. Thus, even when an oxidation layer exists on the surface of the wire 2, the correction layer 5 and the wire 2 are fused and fixed in the respective regions so that the resistance value of the correcting part can be decreased.
