Abstract
There is provided a display device capable of preventing a malfunction and a display defect due to an off-leak from occurring even when a circuit in a shift register is configured utilizing thin film transistors of relatively large off-leaks. In at least one embodiment, each of bistable circuits that constitute the shift register includes: a thin film transistor for increasing a potential of an output terminal based on a first clock; a thin film transistor for decreasing the potential of the output terminal; a thin film transistor for increasing a potential of a range netA connected to a gate terminal of the thin film transistor based on a start signal; thin film transistors for decreasing the potential of the range netA; a capacitor for increasing the potential of a range netB connected to a gate terminal of the thin film transistor; and a thin film transistor for decreasing the potential of the range netB.
