Abstract
In a unit circuit constituting a shift register, as a constituent element for changing the potential of a node (first control node) connected to the gate terminal of an output control transistor from a high level to a low level, two thin film transistors (a first reset transistor and a second reset transistor) connected in series between the first control node and an input terminal for a low-level DC power supply voltage VSS are provided. A capacitor is provided between the drain terminal and the source terminal of each of the two thin film transistors.
