DISPLAY SUBSTRATE, METHOD FOR REPAIRING A BAD THEREOF AND MOTHER SUBSTRATE HAVING THE DISPLAY SUBSTRATE

摘要

A display substrate, a method for repairing the same and a mother substrate having the same are provided to improve the inspection efficiency for the display substrate as easily repairing defects of the display substrate. A source pad unit(210) includes the first voltage input pad(215) for receiving a storage common voltage. A plurality of storage lines deliver the storage common voltage to a plurality of pixels(P). The first voltage line(239) is connected to the first voltage input pad and is extended in a direction crossing the storage lines. The first protrusion unit of the first voltage line is overlapped with one ends of each storage line. A switching element(TR) is connected to a gate line(GL) and a data line(DL). A pixel electrode(PE) is electrically connected to the switching element.
