In one embodiment of the present invention, a liquid crystal display
apparatus driving circuit selectively supplies positive polarity gray
scale voltages or negative polarity gray scale voltages to video signal
lines as video signals. The circuit includes a gray scale voltage
generation circuit for generating a gray scale voltage for display; and
first and second gray scale voltage adjustment sections included in the
circuit, for increasing positive and negative polarity gray scale
voltages while maintaining a voltage difference between the positive and
negative polarity gray scale voltages and respectively adjust a center
potentials of the positive and negative polarity gray scale voltages.
This makes it possible to provide the liquid crystal display apparatus
driving circuit which can make the center values of the positive and
negative polarity gray scale voltages proximate to values which makes it
possible to further reduce the flicker phenomenon without changing the
gray scale property.
