ABSTRACT:
Disclosed herein is a bootstrap circuit configured to employ first, second and third transistors of the same conduction type wherein: a node section connecting a gate electrode of the first transistor and a specific one of the source and drain areas of a third transistor to each other is put in a floating state when the third transistor is put in a turned-off state; a gate electrode of the second transistor is connected to a clock supply line which conveys the other one of the two clock signals; and a voltage-variation repression capacitor is provided between the node section and a first voltage supply line.
