Claim 10:
11. A scan driving circuit, comprising:
a pull-up output charging circuit electrically connected to a first voltage terminal;
a pull-down discharge circuit electrically connected to a second voltage terminal, wherein a first voltage level of the first voltage terminal is higher than a second voltage level of the second voltage terminal;
an anti-noise pull-down discharge circuit electrically connected to the pull-up output charging circuit and the pull-down discharge circuit through a driving node, wherein the pull-up output charging circuit and the pull-down discharge circuit are electrically connected to an output terminal; and
an anti-noise start-up circuit electrically connected to the anti-noise pull-down discharge circuit, wherein in a non-working state, the anti-noise start-up circuit enables the anti-noise pull-down discharge circuit to pull down an electric potential of the driving node, so as to disable the pull-down discharge circuit and to enable the pull-up output charging circuit, thereby pulling up an electric potential of the output terminal.
