摘要： A monostable ferroelectric liquid crystal display in which a stable monostable mode is realized to achieve sufficient analog gradation and contrast. A pair of substrates, processed with uniaxial orientation, are placed so that the directions of orientation processing will be substantially parallel to each other. Into the gap between the two substrates is charged a ferroelectric liquid crystal material. The component of projection on the substrates of the axial direction of a cone drawn by the liquid crystal molecules of the ferroelectric liquid crystal material and that of the axial direction of the liquid crystal molecules themselves are substantially coincident with the direction of the processing for orientation of the substrates. Monostability is achieved with this state as an initial state. The ferroelectric liquid crystal material is a liquid crystal composition including a compound comprised of a phenyl pyrimidine skeleton to each terminal end of which is linked an alkyl chain, with the sum of carbon atoms of the alkyl chains being equal to 17.
