TFT-LCD ARRAY SUBSTRATE AND METHOD FOR REPAIRING BROKEN LINE OF DATA LINE THEREOF

摘要

A TFT-LCD array substrate and a method for repairing a broken line of a data line thereof. The TFT-LCD array substrate comprises a first metal layer, a second metal layer and a transparent electrode layer which are arranged successively from bottom to top; a gate line (2) and a common electrode line are formed in the first metal layer; a data line (1) is formed in the second metal layer; a pixel electrode (3) is formed in the transparent electrode layer; the gate line (2) and the data line (1) are crossed to form a pixel area; the pixel electrode (3) and the common electrode line are arranged in the pixel area; the common electrode line comprises a first electrode line (4) and a second electrode line which are connected to each other; the projection of the second electrode line and that of the data line (1) on the second metal layer are parallel to each other; and the projection of the first electrode line (4) and that of the data line (1) on the second metal layer are intersected.
