Abstract

A bistable circuit includes an input terminal (41) for a set signal, an input terminal (42) for a reset signal, an output terminal (48) for a state signal, a thin-film transistor (M2) for increasing a potential of the output terminal (48) based on a first clock, a thin-film transistor (M1) for increasing a potential of a first-node connected to a gate terminal of the thin-film transistor (M2) based on the set signal, a thin-film transistor (M5) for decreasing the potential of the first-node, a thin-film transistor (M7) for increasing a potential of a second-node connected to a gate terminal of the thin-film transistor (M5) based on the reset signal, a thin-film transistor (M6) for decreasing the potential of the output terminal (48) based on the potential of the second-node, a thin-film transistor (M3) for increasing the potential of the second-node based on the set signal, and a capacitor (CAP2) having one end connected to the second-node and the other end connected to the input terminal (41).
