Abstract
A scan driving device includes: a first node transmitted with a clock signal input to a first clock signal input terminal; a second node transmitted with an input signal according to a clock signal input to a second clock signal input terminal; a first transistor transmitting a power source voltage to an output terminal according to a voltage of the first node; a second transistor formed to transmit the clock signal input to the third clock signal input terminal to the output terminal according to the voltage of the second node; and a dummy transistor formed to transmit the clock signal input to the third clock signal input terminal to the output terminal according to the voltage of the second node. One of the second transistor and the dummy transistor is cut off.
