Claim 4:
5. The display substrate according to claim 1, wherein the gate drive circuit comprises an input sub-circuit, an output sub-circuit, a pull-down sub-circuit, and a reset sub-circuit; wherein
the input sub-circuit is connected to an input signal terminal, a first power line, and a pull-up node, and is configured to output a first power signal supplied by the first power line to the pull-up node in response to an input signal supplied by the input signal terminal;
the output sub-circuit is connected to the pull-up node, a clock signal line, and an output terminal, and is configured to output a clock signal supplied by the clock signal line to the output terminal in response to a potential of the pull-up node;
the pull-down sub-circuit is connected to a second power line, a third power line, a fourth power line, the pull-up node, and the output terminal, and is configured to output a fourth power signal supplied by the fourth power line to the pull-up node and the output terminal in response to the potential of the pull-up node, a second power signal supplied by the second power line, and a third power signal supplied by the third power line; and
the reset sub-circuit is connected to a reset signal terminal, a start signal line, a fifth power line, the fourth power line, and the pull-up node, and is configured to output a fifth power signal supplied by the fifth power line to the pull-up node in response to a reset signal supplied by the reset signal terminal, and to output the fourth power signal to the pull-up node in response to a start drive signal supplied by the start signal line.
