Driving circuit unit, gate driving circuit and display device

The invention relates to a gate driving circuit and a display device. The gate driving circuit comprises multiple levels of driving circuit units connected in series. Each level of units comprises an inputting module for providing threshold voltage of a driving module, a driving module for responding to the threshold voltage and for sending a first clock signal to a signal outputting interface, a discharging module for responding to an output signal or a clock signal of an adjacent level and for coupling a control terminal of the driving module to a first voltage source, a clock feedthrough inhibiting module for stablizing the potential of the control terminal of the driving module under the control of the clock signal and the output signal of the adjacent level, and a low level maintaining module for stablizing the output signal at the potential of the first voltage source under the control of the clock signal. The driving circuit unit, gate driving circuit and display device provided by the invention employ single driving tube to realize the fast pull-up and pull-down of the output signal with sequential coordination, reducing the delay time of the rise and fall of the output signal at a low temperature, and employs the clock feedthrough inhibiting module to stablize the gate potential of the driving tube, reducing the corresponding dynamic power consumption.
