Abstract: A scan driver includes stages dependently connected to each other, where each of the stages outputs a gate signal, where a first scanning start signal is input to a first stage of the stages, where a second scanning start signal is input to a last stage of the stages, where each of the first scanning start signal and the second scanning start signal has one pulse per frame, where the stages sequentially output a gate-on voltage between a time when a pulse of the first scanning start signal for a frame is input to the first stage and a time when a pulse of the second scanning start signal for the frame is input to the last stage, and where the stages output a first low voltage lower than the gate-on voltage after the pulse of the second scanning start signal for the frame is input to the last stage.

Abstract: A display panel includes an amorphous silicon gate driver in which a lower voltage than the gate-off voltage output from the gate driver is applied to an adjacent stage as a low voltage transmission signal.
