Shift register, gate drive circuit and display device

A shift register comprising:

• an input circuit, a reset circuit, a pull-down control circuit and an output circuit;
• wherein:
• the input circuit is configured to, under control of an input signal terminal, provide a signal of the input signal terminal to a pull-up node;
• the reset circuit is configured to, under the control of the input signal terminal and a clock signal terminal, provide a signal of a first reference signal terminal to the pull-up node;
• the output circuit is configured to, under the control of the clock signal terminal and a signal of the pull-up node, provide a signal of a second reference signal terminal to an output signal terminal;
• and
• the pull-down control circuit is configured to reset the output signal terminal according to the signal of the first reference signal terminal.
