Abstract
A unit circuit () includes: a transistor (T) having its drain terminal to be supplied with a clock signal (CK) and its source terminal connected to an output terminal (OUT); a transistor (T) which, when supplied with an active all-on control signal (AON), outputs an ON voltage to the output terminal (OUT), and which, when supplied with a nonactive all-on control signal (AONB), stops outputting the ON voltage; a transistor (T) which supplies the ON voltage to a control terminal of the transistor (T) in accordance with an input signal (IN); a transistor (T) which, when supplied with the active all-on control signal (AON), supplies an OFF voltage to a control terminal of the transistor (T). This makes it possible to provide a shift register of a simple structure that can prevent a malfunction from occurring after all-on operation, and to provide a display device.
