Abstract

The present invention provides a repairing method, a repairing device and a manufacturing method of an array substrate, the repairing method comprises: cutting off electrical connection between the pixel driving circuit and the first electrode in an abnormal pixel unit; forming a first through hole and a second through hole in a pixel defining layer according to positions of a selected candidate pixel unit and the abnormal pixel unit; forming a conductive connection part on the pixel defining layer, the conductive connection part electrically connects to the first electrode in the abnormal pixel unit through the first through hole, and to the first electrode in the candidate pixel unit through the second through hole. In the solutions in the present invention, the pixel driving circuit in the candidate pixel unit is electrically connected to the OLED in the abnormal pixel unit, so that the abnormal pixel unit is repaired.
