Abstract
A flip-flop of the present invention includes: an input terminal; an output terminal; a first control signal terminal and a second control signal terminal; a first output section including a bootstrap capacitor, the first output section being connected to the first control signal terminal and the output terminal; a second output section connected to a first output section source and the output terminal; a first input section connected to the input terminal, the first input section charging the bootstrap capacitor; a discharge section discharging the bootstrap capacitor; a second input section connected to the input terminal, the second input section being also connected to the second output section; a reset section controlling the discharge section and the second output section, the reset section being connected to the second control signal terminal; a first initialization section controlling the first output section; a second initialization section controlling the first input section; and a third initialization section controlling the discharge section and the second output section. This makes it possible to realize a shift register capable of performing an all-ON operation regard…
