ABSTRACT:
A ferroelectric liquid crystal device comprising: a pair of substrates each having a plurality of electrodes oppositely spaced from each other and intersecting with each other, and a ferroelectric liquid crystal layer disposed between the substrates and having a thickness small enough to release a helical structure in the absence of an electric field, a pixel being formed at each intersection of the opposite electrodes formed on the pair of substrates while leaving non-pixel portions at which the opposite electrodes do not face each other. The ferroelectric liquid crystal yields two stable orientation states providing two average molecular axes forming an angle 2.theta. therebetween under no electric field. The ferroelectric liquid crystal yields two states providing two average molecular axes forming an angle 2 .circle.H therebetween. The ferroelectric liquid crystal at the non-pixel portions forms an orientation state providing an average molecular axis forming an angle .theta. or -.theta..
