Abstract
A scan driving circuit is disclosed, and the scan driving circuit has a pull-up control module, a pull-up module, a pull-down module, a pull-down maintaining module, a down-stream module and a bootstrap capacitor; when the pull-up control module generates a scan level signal, the pull-up control module and the pull-down maintaining module use a constant high-level voltage to avoid an electrical leakage phenomenon; and the pull down module uses a present-level scan signal to avoid the electrical leakage phenomenon. Thus, the electrical leakage phenomenon can be efficiently avoided.
