ABSTRACT:
A level shifter13is provided for each of SR flip flops F1constituting a shift register11.The level shifter13increases a voltage of a clock signal CK. This arrangement reduces a distance for transmitting a clock signal whose voltage has been increased, as compared with a construction in which a voltage of a clock signal is increased by a single level shifter and the signal is transmitted to each of the flip flops; consequently, a load capacity of the level shifter can be smaller. Furthermore, each of the level shifters is operated during a pulse output of the previous level shifter13,and the operation is suspended at the end of the pulse output. Thus, the level shifters13can operate only when it is necessary to apply a clock signal CK to the corresponding SR flip flop F1.As a result, even when an amplitude of a clock signal is small, it is possible to reduce power consumption of the shift resister under normal operation.
