A display substrate is provided to easily perform the laser-cutting process on a common electrode line, by forming the common electrode to have different widths such that a portion of the common electrode is apart from a data line at a large distance. A plurality of data lines cross with a plurality of gate lines. A pixel electrode(120) is formed in a pixel region, which is defined by one gate line and neighboring two data lines. A common electrode line(130) faces the pixel electrode to form an auxiliary capacitor within the pixel region. The common electrode line has a first formation width in a region parallel to the data lines and a second formation width relatively smaller than the first formation width.
