Abstract
A scan driver includes scan driving blocks, each including: a first transistor including a gate coupled to a first node and receiving a first clock signal, a first electrode receiving an output control signal, and a second electrode coupled to a scan line at first output; a second transistor including a gate coupled to a second node receiving an input signal according to a second clock signal, and first and second electrodes respectively coupled to a third clock input and the first output; a third transistor including a gate coupled to the first node, a first electrode receiving the output control signal, and a second electrode coupled to an input terminal of a next scan driving block at a second output; and a fourth transistor including a gate coupled to the second node, and first and second electrodes respectively coupled to the third clock input and the second output.
