Abstract

Embodiments of the present disclosure propose a shift register, a driving method thereof, a gate driving circuit, and a display device. The shift register includes: an inputting sub-circuit, an outputting sub-circuit, a resetting sub-circuit, a pulling-down sub-circuit, a pulling-down controlling sub-circuit, and a voltage regulating sub-circuit. The voltage regulating sub-circuit is coupled to a pulling-down node, a pulling-down controlling node, a second clock signal terminal, a third clock signal terminal, a first voltage signal terminal and a second voltage signal terminal, and is configured to regulate a voltage at the pulling-down controlling node based on a first voltage signal from the first voltage signal terminal and a second voltage signal from the second voltage signal terminal, under a control of the second clock signal from the second clock signal terminal, a third clock signal from the third clock signal terminal, and the voltage at the pulling-down node.
