Abstract
A scan driving device including scan driving blocks including a first node receiving a second-voltage according to a signal input to a first-input terminal, a second node receiving a first-voltage according to a signal input to the first-input terminal, and receiving an input signal according to a clock signal input to a second-input terminal, a first transistor connected to the first node, the first power source, and an output terminal, and a second transistor connected to the second node and the output terminal and configured to receive a clock signal input to a third-input terminal, wherein, during the initial driving period, the input signal is applied with a gate-off-voltage, and clock signals input to the first-, second-, and third-input terminals are applied with a gate-on-voltage to reset a voltage at the first node with the gate-on-voltage and reset a voltage at the second node with the gate-off-voltage.
