A long-line repair method for a COA array substrate comprises: providing via holes (6) at two ends of a long-line area to expose a data line (22), removing a transparent electrode (5) and coloured resistors (41, 42) of the long-line area to form a groove (7), and forming long-line metal (8) in the groove (7) and connecting two ends of the long-line metal (8) to the data line (22) through the via holes (6), thereby implementing the long-line repair for the data line (22). |
