    摘要: A shift register unit and a driving method thereof, a scan driving circuit and a display device, wherein the shift register unit comprises an input terminal (INPUT), an output terminal (OUTPUT), a reset terminal (RESET), and a first noise leak terminal (LEAK1), and further comprises an output pull-down module (14), and also an input module (11), an output module (12), a reset module (13) and a first noise leak module (15) that are connected to a first node (PU), the input module (11) being configured to pull up a voltage at the first node (PU) under control of a signal received at the input terminal (INPUT), the first noise leak module (15) being configured to release a noise voltage at the first node (PU) to the first noise leak terminal (LEAK1) under control of a third clock signal (CLK1), and to disconnect an electrical connection between the first noise leak terminal (CLK1) and the first node (PU) during a time period in which the voltage at the first node (PU) is pulled up, by which a stable output of the GOA unit with noise interference being eliminated can be achieved with relatively few circuit elements.
