A selection-addressing-type liquid crystal display selectively addresses a
signal line of a pixel unit using groups of three selectors of a selector
circuit in a time-division manner. A level converter level shifts
selector pulses having a voltage swing corresponding to the
external-circuit power supply to selector pulses having a voltage swing
corresponding to the internal-circuit power supply. In a non-display
region in partial display mode, the level converter is deactivated under
the control of a control signal to reduce direct current consumption
therein.
