Array substrate and repairing method

The embodiment of the invention discloses an array substrate and a repairing method. The array substrate comprises a substrate, a first electrode and a second electrode, a plurality of data lines and a plurality of scanning lines, wherein the plurality of data lines and the plurality of scanning lines are crossed to define a plurality of pixel areas; a plurality of conductive electrodes; wherein the data line comprises a main body part, a plurality of protruding parts and at least one connecting part, the connecting part is arranged on the at least one protruding part, and the orthographic projection of the protruding parts and the orthographic projection of the connecting part on the substrate are at least partially overlapped with the conductive electrode. According to the embodiment of the invention, the data line is arranged to be in the shape comprising the main body part, the protruding part and the connecting part, and when the data line is disconnected, the data line can be repaired through the protru
