A switch set used in a bi-directional shift register circuit includes a plurality of switch devices. Each switch device is controlled by corresponding control signals to switch the direction of the input signal. One of the switch devices includes a first switch unit for transmitting a shift register signal from a previous shift register to a shift register according to a first control signal, a second switch unit for transmitting a shift register signal from a next shift register to the shift register according to a second control signal. The first and the second control signals have the same frequency as the clock signal of the shift register circuit.
