PURPOSE: A scan driving circuit and a repairing method thereof are provided to easily repair a scan drive circuit by using a repair line when a defect occurs in the scan drive circuit, thereby improving the manufacturing yield of a display device. CONSTITUTION: A shift register outputs a first scan signal, which is successively applied for each scan line, to a first output line during a partial section of one frame period. A simultaneous driving circuit(SSi) outputs a second scan signal, which is simultaneously applied for the entire scan lines, to a second output line during a section excluding the partial section. A switching device(TRss) is electrically connected with the second output line. A repair line(228) is formed to cross the first output line and the second output line.
