摘要： A liquid crystal apparatus comprises a liquid crystal device having a pair of substrates respectively having thereon scanning electrodes and data electrodes arranged in a matrix shape, and a liquid crystal disposed between the substrates and capable of a cumulative translational movement depending on a change in an external electric field applied to the liquid crystal; and a driver for controlling a first frequency f having a variable range and representing an effective frequency of a drive data signal pulse applied to the liquid crystal so that a second frequency f.sub.0 representing an inversion frequency at which a direction of the translational movement of the liquid crystal is turned in an opposite direction is in the variable range of the first frequency f. The above driver used in the liquid crystal apparatus is effective in suppressing a cumulative translational movement of liquid crystal molecules for a long period of time.
