[0080] This embodiment introduces in detail the specific repairing method of the array substrate with repaired lines of the present invention.

[0081] Figure 7 It is a flow chart of the method for repairing defects of the array substrate in the third embodiment of the present invention. FIG. 8 is a schematic diagram of the array substrate of the liquid crystal display device repaired by the repair method in the third embodiment of the present invention. The following combines Figure 7 and FIG. 8 specifically introduce the repairing method of this embodiment.

[0082] Step 701: Detect and determine the defects of the data lines on the array substrate. As shown in FIG. 8 , open circuit defects 841 and 842 appear on the data lines D(n+3) and D(n+5), respectively. If the array substrate does not have the repaired circuit of the present invention, the two columns of pixel units cannot display normally, and the array substrate can only be scrapped. However, the array substrate...
