Abstract
A scan driver has a plurality of stages configured to supply a scan signal to scan lines. The plurality of stages include a stage coupled to a scan line of the scan lines. The stage includes a first transistor including a gate electrode, a drain electrode and a source electrode and is configured to output the scan signal to the scan line; a second transistor provided on a side of the first transistor and connected to the drain electrode; a third transistor provided on the side of the first transistor and connected to the source electrode; a capacitor provided between the scan line and the first transistor; a first dummy transistor provided between the first transistor and the capacitor and connected to the capacitor; and a second dummy transistor provided between the first transistor and the second transistor and connected to both the first transistor and the second transistor.
