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.
