A bi-directional shift register circuit includes multiple stages of shift registers for generating multiple gate driving signals. At least one shift register includes an input stage circuit, an output stage circuit, a first and a second transistor. The input stage circuit is coupled to a first and a second signal input terminal The output stage circuit receives a first clock signal and generating a corresponding gate driving signal. The first transistor includes a first terminal coupled to a first node, a second terminal coupled to a second node and a third terminal coupled to a high operation voltage. The second transistor includes a first terminal coupled to the second node, a second terminal coupled to the first node and a third terminal coupled to the high operation voltage. The first transistor charges the first node and the second transistor discharges the second node.
