Abstract:
A monostable ferroelectric liquid crystal display apparatus comprising:a pair of substrates, each subjected to uniaxial orientation processing and arranged so that their orientation processing directions are approximately parallel to each other, and a ferroelectric liquid crystal material having the chiral smectic C phase filled between the substrates, in which both a projection component of an axis of a cone drawn by a molecule of the ferroelectric liquid crystal material onto the substrate and the projection component of the liquid crystal molecule axis onto the substrate are identical to the orientation processing direction of the substrates, wherein the ferroelectric liquid crystal contains a compound having a dicyclic phenyl pyrimidine skeleton having one end connected to an alkoxyl chain and the other end connected to an alkyl chain in which the sum of carbons in the alkyl chain is 15, wherein a weight % content of the compound in the liquid crystal material is in a range from 1 weight % to 60 weight % of the liquid crystal material.
