Summary:A shift register and a display apparatus are provided. The shift register includes a pre-charge unit, a pull-up unit, a first pull-down unit and a second pull-down unit. The pre-charge unit receives first and second input signals, and outputs a pre-charge signal via a first node. The pull-up unit receives a pre-charge signal and a clock signal, and outputs a scanning signal via a second node. The first pull-down unit receives the pre-charge signal, first and second pull-down control signals, and controls whether to pull-down the scanning signal to a reference voltage level. The second pull-down unit receives the pre-charge signal, first and second pull-down control signals, and controls whether to keep the scanning signal at the reference voltage level. The duty cycle of the clock signal is less than 50 percent.
