Abstract
The present disclosure provides a shift register, a gate driving circuit and a display panel, and belongs to the field of display technology. The shift register of the present disclosure includes: an input circuit configured to precharge and reset a pull-up node; one pull-down control circuit being electrically connected to one pull-down circuit through a pull-down node; the pull-down control circuit being configured to control a potential at the pull-down node under a first power voltage; each pull-down circuit being configured to pull down the potential at the pull-down node in response to a potential at the pull-up node; an output circuit configured to output a clock signal through a signal output terminal in response to the potential at the pull-up node; one first noise reduction circuit connected to one pull-down node.
