Abstract
A novel ferroelectric liquid crystal (FLC) EO (electro-Optic) cell showing a quasi-tristate has been demonstrated by using an FLC material ZLI-4139 (Merck) together with orientation films of polyimide RN-626 (Nissan Chem. Ind) which are rubbed in antiparallel way and are capable of generating a high pretilt angle.
The EO cell showing the quasi-tristates was characterized in term of the dynamic behavior of the dielectric constant, switching current, and D-E hysteresis.
