ABSTRACT:
A driver circuit for a liquid crystal display for driving a liquid crystal panel in an A.C. manner. In this circuit, a display signal voltage to be applied to one electrode of the liquid crystal cell and a common voltage to be applied to a common electrode thereof are inverted in their polarity with a certain period, respectively, and at least one of the signal voltage and common voltage that are being polarity-inverted with the certain period is varied in its D.C. level by the same amount in the same direction in each period so that they can be adjusted so as to be in a predetermined relation for A.C. driving.
