Claim Text:
1. A shift register unit, comprising: an inputting module configured to enable a first node to be in electrical connection to a first voltage signal line under the control of a signal applied to an input end, the first node being a connection point between the inputting module and a pulling-up module; a resetting module configured to enable the first node to be in electrical connection to a second voltage signal line under the control of a signal applied to a reset end; the pulling-up module located between the first node and an output end, and configured to enable a first clock signal line to be in electrical connection to the output end under the control of a voltage at the first node; a pulling-down controlling module configured to control a voltage at a second node according to the voltage at the first node, the second node being a connection point between the pulling-down controlling module and a pulling-down module; and the pulling-down module configured to pull down the voltage at the first node and a voltage at the output end according to the voltage at the second node, wherein the pulling-down module comprises a tenth switch element which is controlled so as to enable the first node to be in electrical connection to a first low-level voltage line, and the pulling-down module further comprises a cut-off enhancement unit configured to cut off a connection between one end of the tenth switch element and the first low-level voltage line when the tenth switch element is in an off state.
