A gate driver is provided. The gate driver includes a plurality of cascade-connected stages. The k-th stage of the stages includes a switching unit for connecting a first node to a second node, a driving unit for generating an output signal in accordance with a voltage of the first node, and an input unit for inputting an output signal of a (k−1)-th stage of the stages and an output signal of a (k+1)-th stage of the stages to the second node.
