The invention provides an array substrate, a method for repairing a broken data line and a display device and belongs to the technical field of liquid crystal display. The array substrate, the method for repairing the broken data line and the display device can solve the problem that an existing broken array substrate data line is difficult to repair. The array substrate comprises a substrate body, grid lines, public electrode lines and data lines. A plurality of pixel units are defined by the grid lines and the data lines. The public electrode lines comprise the first public electrode lines arranged in the first direction and second public electrode lines arranged in the second direction, and the first public electrode lines and the second public electrode lines are of an integrated structure. The data lines comprise data line bodies and a plurality of repairing parts which are connected with the data line bodies and extend to the part above the public electrode lines. The repairing parts are used for being welded with the first public electrode lines and/or the second public electrode lines corresponding to the pixel units together when the data line bodies corresponding to the pixel units are broken, and therefore the data lines are repaired.
