| Zusammenfassung: | The present invention includes a scan driving unit having a display panel displaying an image and a scan signal generation circuit unit supplying a scan signal to the display panel. The scan signal generation circuit comprises: a first transistor for controlling charging and discharging of a Q node; a second transistor to control charging and discharging of a QB node; a third transistor for resetting the QB node; a fourth transistor for outputting a scan signal of a logic low in response to the potential of the Q node; and a fifth transistor for outputting the scan signal of the logic high in response to the potential of the QB node.
