Abstract
The invention discloses a method to renovate defects of lines and a liquid crystal display device. The method comprises: a. a scanning line renovating line with the same extending direction with a data line and a scanning line is respectively arranged at the conductive layers in different layers of the scanning line and the data line; b. when line breaking occurs in the n scanning line, the scanning line renovating line is truncated by laser from the nth scanning line to the outer part of other scanning lines; c. the overlapped part of the scanning line and the scanning line renovating line is perforated by laser, thereby the breaking line is renovated. The device comprises a scanning line and a data line. A scanning line renovating line with the same extending direction with the data line and the scanning line is arranged at the conductive layers in different layers of the scanning line and the data line. Renovating lines are buried beforehand in the method and the device. Once turnoff of the circuit occurs, the relative renovating lines are truncated and touching holes are perforated, then the breaking lines can be renovated. The operation is simple, and renovating can be conveniently processed even the lines are assembled in cases. Thereby the renovating efficiency is greatly improved and producing cost is reduced at the same time.
