Abstract

This invention provides a shift register which can use the bootstrap operation to reduce the output impedance and to suppress the variation of the gate voltage of an output transistor, and can prevent the unnecessary output of the drive pulse, and a liquid crystal driver using the shift register. The shift register in this invention has a plurality of stages in longitudinal connection to proceed shifting of the input data to output signal of the shift operation. Each stage has a first diode connected to the gate of the output transistor to receive the input data, a capacitor connected between the gate and the source of the output transistor, and a clamping transistor in parallel connection with the capacitor between the gate and the source of the output transistor. The source of the clamping transistor and the source of the output transistor are connected. The drain of the clamping transistor and the gate of the output transistor are connected.
