Claim:
1. A shift register unit, including a signal input unit, a latch unit, a pull-down unit and a signal output unit, wherein the signal input unit is used for outputting a first level signal or a second level signal to a first terminal of the latch unit under the control of an input signal and a reset signal; the latch unit is used for latching the signal input from the signal input unit and outputting a latched processed signal to the pull-down unit; the pull-down unit is used for outputting the first level signal or a pull-down signal to the signal output unit under the control of the latched processed signal; and the signal output unit is used for receiving and inverting the signal output from the pull-down unit to generate an output signal, and outputting a signal being opposite to the output signal, wherein the pull-down unit includes a fourth thin film transistor T the fourth thin film transistor T the fifth thin film transistor T
