A scan driving circuit includes a pull-up assembly, a pull-up control assembly that drives the pull-up assembly, a pull-down maintaining assembly, and a reference low-level signal. The reference low-level signal includes a first reference low-level signal and a second reference low-level signal. When the current scanning line is inactive, the pull-down maintaining assembly controls the reference low-level to be sent to the current scanning line and the output end of the pull-up control assembly according to a pull-down maintaining signal.
