Abstract:
1. A shift register having a plurality of unit circuits connected in multiple stages and operating based on multiple-phase clock signals, the unit circuits being configured by transistors of the same conductivity type, the shift register comprising: a detection circuit for outputting an active detection signal upon detection of the unit circuits being activated; and a restoration execution circuit for deactivating the unit circuits based on the active detection signal, wherein the unit circuits each include, the restoration execution circuit activates the discharge circuit, thereby providing an off-voltage to the control terminal of the output control transistor, wherein, the unit circuits each include the restoration execution circuit, and the detection circuit provides the active detection signal to the unit circuits upon detection of all output signals from two or more unit circuits being activated, the two or more unit circuits being arbitrarily selected from either even- or odd-numbered-stage unit circuits connected to the same clock signal line.
