Gate drive circuit, display substrate having the same, and method thereof

A display substrate comprising:

• a plurality of pixel parts formed in a display area of a base substrate, the pixel parts electrically connected to a plurality of data lines extended along a first direction and a plurality of gate lines extended along a second direction crossing the first direction;
• and
• a gate drive circuit comprising:
• a shift register formed in a peripheral area surrounding the display area, the shift register including a plurality of stages to output a plurality of gate signals;
• a clock wiring electrically connected to a plurality of clock connecting wirings extended along the second direction to deliver a clock signal to the stages;
• and
• a start wiring including a first wiring extended along the first direction and a second wiring connected to the first wiring and extended along the first direction to cross with the clock connecting wirings so as to deliver a vertical start signal to a first stage among the stages,
• wherein capacitors are formed where the second wiring of the start wiring crosses the clock connecting wirings, and static electricity applied to the start wiring is dispersed through the capacitors to decrease energy of static electricity applied to the shift register.
