Abstract
Disclosed herein is a shift register, a grid driver circuit and a display device. The shift register may comprise a first pull-down point control circuit having a control end coupled to a pull-up point and two ends coupled to a pull-down point and a first voltage input respectively, a second pull-down point control circuit having two control ends coupled to an input signal and a control input respectively and two ends coupled to the pull-down point and the first voltage input respectively, a first pull-up point control circuit having a control end coupled to the pull-down point and two ends coupled to the pull-up point and the first voltage input respectively, and a second pull-up point control circuit having a control end coupled to a first clock signal and two ends coupled to the pull-up point and the first voltage input respectively.
