A scan driving device comprises a plurality of scan driving blocks which are sequentially disposed. Each of the plurality of scan driving devices comprises: a first node in which a clock signal inputted to a first clock signal input terminal is transmitted; a second node in which an input signal is transmitted according to a clock signal inputted to a second clock signal input terminal; a first transistor for transmitting a power source voltage to an output terminal according to a voltage of the first node; a second transistor formed to transmit a clock signal inputted to a third clock signal terminal to the output terminal according to a voltage of the second node; and a dummy transistor for transmitting a clock signal inputted to the third clock signal terminal to the output terminal according to the voltage of the second node, wherein one of the second transistor and the dummy transistor is cut off.
