Abstract
A shift register circuit has a plurality of unit circuits that are cascade-connected to one another and that output received pulse signals as output signals in accordance with a clock signal, the shift register circuit sequentially outputting the output signals from the plurality of respective unit circuits. The output circuits each include a double-gate transistor having first gate electrode that controls conductivity between the drain electrode and the source electrode, and a second gate electrode formed through an insulating layer and disposed to face the first gate electrode across a semiconductor layer between the drain electrode and the source electrode. The shift register circuit applies a prescribed voltage to the second gate electrode in accordance with a voltage applied to the first gate electrode.
