Abstract
The present invention provides a scan driving circuit utilized to drive cascading scan lines. The scan driving circuit comprises a pull-down control module, a pull-down module, a reset control module, a reset module, a lower transmission module, a first bootstrap capacitor, a constant low voltage source, and a constant high voltage source. By use of the deployment of the reset module, the scan driving circuit of the present invention improves the stability of the scan driving circuit and meanwhile, the structure of the whole scan driving circuit is simplified.
