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.

Abstract: A driver is disposed in a display panel, and includes a plurality of stages. At least one stage of the plurality of stages includes an input circuit which transfers an input signal to a first node in response to at least one of a clock signal and an inverted clock signal, and inverters which generate an output signal based on a voltage of the first node. At least one of the inverters includes a p-type metal-oxide-semiconductor (“PMOS”) transistor and an n-type metal-oxide-semiconductor (“NMOS”) transistor connected in series between a line transferring a relatively high gate voltage and a line transferring a relatively low gate voltage. A first active region of the PMOS transistor includes a material different from a material of a second active region of the NMOS transistor.
