Abstract
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. When the current scanning line is inactive, the pull-down maintaining assembly is controlled by a pull-down maintaining signal to make a reference low-level signal be sent to an output end of the pull-up control assembly and the current scanning line.
