ABSTRACT:
A shift register includes a sampling circuit to sample an input signal in response to a start pulse and two clock signals having different duty ratios from each other, a holding circuit to hold the input signal in response to an output signal of the sampling circuit and the two clock signals, an inverter to invert the output signal of the sampling circuit or the holding circuit, and a NAND gate to receive the output signal of the sampling circuit or the holding circuit and the output signal of the inverter and perform a logical operation on the received output signals to output an output signal. The first clock signal has a duty ratio smaller than the second clock signal. The sampling circuit and the holding circuit have a three-stack structure in which three transistors are coupled with one another in series.
