Abstract: A scan driver includes a plurality of stages sequentially connected to each other. Each of the plurality of stages includes first and second output transistors and first to fourth control transistors. The second control transistor is connected between a second node and a first voltage terminal and to an input terminal and operates in response to a start signal or a previous carry signal provided through the input terminal. Each of the first and second output transistors and the first, third, and fourth control transistors is a first type, and the second control transistor is a second type different from the first type.
