Abstract: A scan driver includes circuit stages for sequentially outputting scan signals, each one of the circuit stages including a signal generator for generating signals provided at a first node and a third node based on a carry signal and a second clock signal, the signal generator including a (2-1)-th transistor including a control electrode connected to the third node and a first electrode for receiving the second clock signal, and a (2-2)-th transistor including a control electrode for receiving a low driving voltage, a first electrode connected to a second electrode of the (2-1)-th transistor, and a second electrode connected to the first node, a first node controller for applying a boosting voltage to the first node based on a first clock signal, and a pull up/down circuit for pulling the scan signal up/down to a high/low voltage based on a signal applied to a second node.
