Stage circuit and scan driver using the same

The present invention relates to a stage circuit which supplies a scan signal with a simultaneous or interlace method. The stage circuit according to the present invention includes: a sequence driving unit which outputs the scan signal to an output terminal by corresponding to a plurality of clock signals which are simultaneously or successively supplied and is disconnected to the output terminal when a third control signal is supplied; and a simultaneous driving unit which outputs the scan signal to the output terminal by corresponding to a first control signal and a second control signal which are not overlapped and is disconnected to the output terminal when a fourth control signal which does not overlap the third control signal is supplied.
