ABSTRACT:
A ferroelectric liquid crystal device which comprises at least one pair of counterposed substrates, a ferroelectric liquid crystal material provided between the substrates, means for applying an electric field to the liquid crystal material and provided at the substrates, an alignment-controlling layer provided on the surface on the liquid crystal material side of each of the substrates, and a sealing member at the peripheral edges of the substrates, the alignment-controlling layer being a film of an organic polymer whose .beta. dispersion temperature is higher than the curing temperature of a sealant for the sealing member, preferably at least 200.degree. C., has a good alignment state of ferroelectric liquid crystal molecules achieved by cooling alone without any application of an electric field and has good display qualities such as a high contrast.
