Scan driver and display device including the same

A scan driver for a display device comprising:

• first to n-th (where n is a natural number greater than or equal to 2) scan signal output circuits to apply scan signals to scan lines, respectively, the first to n-th scan signal output circuits being connected to each other through the scan lines,
• wherein each of the first to n-th scan signal output circuits includes:
• a drive circuit to apply a first drive signal to a first drive node, to apply a second drive signal to a second drive node, and to apply a connection signal to a connection signal output node based on i) an input signal which is one of either a scan start signal or a scan signal applied by another scan signal output circuit, ii) a clock signal, and iii) an on-level voltage;
• and
• a buffer circuit to receive the connection signal, the first drive signal, and the second drive signal from the drive circuit, and to output one of the scan signals to one of the scan lines based on the first drive signal, the second drive signal, and the clock signal.
