摘要： In a shift register for driving a pixel row in a liquid crystal display device a plurality of stages are connected: to a high level voltage source, a low level voltage source and a phase-delayed clock signal generator; to row lines; and in cascade, with respect to a scanning signal, for charging and discharging the row lines. Each stage of the shift register has a pull-up transistor, a pull-down transistor, and first to fourth transistors. The pull-up transistor has a control electrode and a conduction path connected between the first clock signal line and the output terminal. The pull-down transistor has a control electrode and a conduction path connected between the low level voltage line and the output terminal. The first and second transistors have conduction paths connected in series between the input terminal and the control electrode of the pull-up transistor, and each has a control electrode connected commonly to the second clock signal line. The first and second transistors allow a voltage to be charged on the control electrode of the pull-up transistor. The third and fourth transistors have conduction paths connected in series between the third clock signal line and the control electrode of the pull-down transistor, and each has a control electrode connected commonly to the third clock signal line. The third and fourth transistors allow a voltage to be charged on the control electrode of the pull-down transistor.

摘要： PURPOSE: A shift register circuit is provided to reduce the number of clock supply lines by driving a liquid crystal cell in a driving circuit for driving a pixel row of LCD, and reduces the number of level shifters. CONSTITUTION: A shift register is connected to a part for generating a high-potential supply voltage, a low-potential supply voltage, and clock signal. Many stages use an output signal of a previous terminal as a starting signal, thereby driving row lines. In the output circuit, the stage responds to a first control signal, and provides a first clock signal to the row line, so that the row line is charged. A voltage on the row line is discharged in response to the second control signal. The input circuit charges/discharges the first control signal in response to the second clock signal through an input line of the start signal, and charges/discharges the second control signal in response to the first control signal and the first clock signal. Thereby, the number of clock supply lines is reduced and the number of level shifters is reduced.
