Abstract: A unit circuit constituting each of stages of a shift register is provided with a thin film transistor, the thin film transistor including a control terminal applied with one of a plurality of gate clock signals, a first conduction terminal connected to a third node, and a second conduction terminal applied with a direct current power supply voltage of a low level. The third node is connected to a control terminal of a thin film transistor configured to change a potential of a second node toward a high level. When a gate clock signal applied to a control terminal of a thin film transistor configured to change a potential of the third node toward the high level changes from the high level to the low level, the gate clock signal applied to the control terminal of the thin film transistor changes from the low level to the high level.
