A display substrate includes a source pad part, a plurality of storage wirings and a first voltage wiring. The source pad part includes a first voltage input pad receiving a storage common voltage. The storage wirings transmit the storage common voltage to a plurality of pixels. The first voltage wiring is connected to the first voltage input pad to be extended in a direction crossing the storage wirings. The first voltage wiring includes a first protrusion part overlapping a first end portion of each of the storage wirings. Therefore, defects of the display substrate may be detected by an electrical test and then repaired, and test efficiency of the display substrate may be enhanced.
