    Abstract

    High contrast and excellent homeotropic alignment of high birefringence (&UDelta; n ∼ 0.3) and negative dielectric anisotropy difluorotolane liquid crystals were demonstrated using long chain alcohol evaporated SiO2 inorganic layers and buffed polyimide layers. The addition of 5-10% isothiocyanatotolane not only improves the contrast ratio but also enhances the figure-of-merit. A disadvantage is the increased threshold voltage.
