The liquid crystal display apparatus is provided with a display unit, a
video signal driving circuit, a scanning signal driving circuit, a common
electrode potential controlling circuit, and a synchronizing circuit. The
display unit has a scanning electrode, a video signal electrode, a
plurality of pixel electrodes arranged in matrix form, a plurality of
switching elements which transmit video signals to the pixel electrodes,
and a common electrode. After the scanning signal driving circuit scans
the entire scanning electrodes and transmits video signals to the pixel
electrodes, the common electrode potential controlling circuit changes
the potential of the common electrode into a pulse shape, overdrives
video signals, or increases a torque required to return to a state in
which no voltage is applied.
