ABSTRACT OF THE DISCLOSURE A liquid crystal apparatus comprising a ferro- electric liquid crystal device matrix having electrodes, including scanning electrodes and signal electrodes spaced from and intersecting with each other, and a ferroelectric liquid crystal disposed between the scanning electrodes and the signal electrodes, a driving circuit for applying a driving voltage selectively to the intersections of the scanning electrodes and the signal electrodes, and a uniform electric field application circuit for applying an alternating electric field to all or a prescribed part of the intersections before the application of said driving voltage; said ferroelectric liquid crystal providing two average molecular directions forming an angle 2.theta.a therebetween in the absence of an electric field after application of an alternating electric field, said angle 2.theta.a being larger than an angle 2.theta. formed between two average molecular directions of the ferroelectric liquid crystal in the absence of an electric field before application of the alternating electric field.
