Abstract

A scan driving device and a driving method thereof are disclosed. The scan driving device includes a plurality of scan driving blocks, and each of the plurality of scan driving blocks includes a first transistor configured to transfer a clock signal inputted to a first clock signal input terminal to a first node according to a first input signal inputted to a first input signal input terminal; a second transistor configured to transfer a first power source voltage to a second node according to a voltage of the first node; and a third transistor configured to transfer the clock signal inputted to the first clock signal input terminal to an output terminal connected to a scan line according to the voltage of the fourth node. The scan driving blocks may also include a plurality of capacitor configured to store and/or change voltage at a plurality of nodes.
