FERROELECTRIC LIQUID CRYSTAL DEVICE

摘要

A liquid crystal apparatus, comprising a liquid crystal device comprising matrix electrodes including scanning signal lines and information signal lines spaced from and intersecting with each other, and a ferroelectric liquid crystal disposed between the matrix electrodes, 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 alternating voltage, which angle 2.THETA.a is larger that 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 voltage, each intersection of the scanning signal lines and the information signal lines in combination with the ferroelectric liquid crystal disposed therebetween constituting a picture element; a scanning signal side driver circuit, and an information signal side driver circuit; said liquid crystal apparatus being so constructed that an alternating voltage is applied to the whole picture elements prior to application of display signals according to multiplex driving scheme.
