Title: Liquid crystal electrooptic device
Inventor: HAGIWARA TOSHIMITSU
IPC: C09K19/20
Filed: 1988-05-26
Abstract: PURPOSE:To improve productivity without sacrificing characteristics such as high-speed responsiveness and high contrast by making use of the change in the state that specific ferroelectric liquid crystal mixture molecules attain caused by the inversion of the direction of the electric field impressed to said liquid crystal mixture. CONSTITUTION:The ferroelectric liquid crystal mixture contg. the liquid crystal compsn. which is of >=8C, has plural side chains and has the optically active group having asymmetric carbon atoms within the molecule is injected into a liquid crystal cell. The liquid crystal mixture is in the state in which spirals can be formed so as to have spiral axes in the direction perpendicular to a smectic layer in the liquid crystal cell. The electric field is impressed from the outside to the ferroelectric liquid crystal in this state and the change in the state which the liquid crystal molecules attain caused by the inversion of the direction of the impressed electric field is utilized. Namely, the liquid crystal molecules are unified to, for example, the 1st state I according to the direction of the impressed electric field by the spontaneous polarization possessed by said molecules. The molecules are unified to another 2nd state II when the reverse electric field is impressed thereto. The difference of the 1st state I and the 2nd state II is utilized. The productivity is thereby improved without sacrificing the characteristics such as high speed response and contrast.
