Abstract
A scan driver includes scan stages, an n-th scan stage of the scan stages includes a first driving circuit, a second driving circuit, and an output circuit. The first driving circuit controls a voltage of a first driving node, based on an input signal and a voltage of a second driving node. The second driving circuit controls the voltage of the second driving node, based on a second clock signal and a first voltage. The output circuit outputs a first clock signal as a scan signal and a carry signal, and outputs a second voltage as the scan signal and the carry signal. The first driving circuit includes a first transistor including a gate electrode electrically connected to the second driving node, one electrode electrically connected to an input line that provides the input signal, and another electrode electrically connected to the first driving node.
