Abstract
A shift register for scanning a liquid crystal display includes cascaded stages. A given stage is formed with an input transistor switch that is responsive to an output pulse of a stage upstream in the chain of the cascaded stages. An output pulse of the given stage is produced in a pull-up transistor of a push-pull amplifier. A third transistor responsive to an output signal of a stage downstream of the given stage applies a control signal to a gate electrode of the pull-down transistor to render the pull-down transistor conductive.
