Abstract:
A monostable ferroelectric liquid crystal display device made up of a pair of substrates, which have been subjected to uniaxial orientation processing, and which are arranged facing each other so that the respective directions of the orientation processing will be subsequently parallel to each other, and a ferroelectric liquid crystal material which has a chiral smectic C phase, and which is charged between these substrates, with a projection component on the substrates of an axial direction of a cone drawn by a liquid crystal molecule of said ferroelectric liquid crystal and with a projection component on the substrates of an axial direction of the liquid crystal molecule itself being subsequently equal to the direction of the orientation processing of the substrates, with the liquid crystal device being mono-stabilized with this state as an initial state,wherein the ferroelectric liquid crystal material is a liquid crystal composition containing a compound comprised of a phenyl pyrimidine skeleton on both terminals of which are linked alkyl chains the sum total of carbon atoms of which is equal to 17, said compound having a content in said liquid crystal composition of 1 to 50 wt %.
