Abstract
A shift register, a stage-shift gate driving circuit and a display panel are provided. The shift register includes a down-delivering module, an output module, a first pull-down maintaining module, a second pull-down maintaining module, a first pull-down module and a second pull-down module. The down-delivering module is for receiving a stage-shift signal(s) from a preceding-stage shift register. The output module is for outputting stage-shift signals and a scan signal. The first pull-down maintaining module, the second pull-down maintaining module, the first pull-down module and the second pull-down module are for keeping the output signal of the output module to be a low voltage level after the output module outputs the scan signal. By the above solution, the invention can reduce the size of transistor, prevent the deterioration of transistor and increase the circuit output capability.
