Abstract
A liquid crystal display and a shift register unit thereof are provided. The shift register unit includes a first switch, a second switch, and a level shift circuit. The first switch has a first input terminal, a first control terminal, and a first output terminal. The second switch has a second input terminal, a second control terminal, and a second output terminal. The second control terminal is coupled to the first output terminal and the level shift circuit. When the first switch is enabled, the first input terminal receives an input signal converting the voltage of the second control terminal into a first voltage for turning on the second switch. The second output terminal outputs a first clock signal to a scan signal line. When the level shift circuit is enabled, the voltage of the second control terminal is converted into a second voltage for turning off the second switch.
