Apparent Tilt Angle and Structural Investigations of the Fluorinated Antiferroelectric Liquid Crystal Material for Display Application

摘要

Recently the investigation in the field of display technology has been boosted by the availability of new materials. The mostly promised solution for that looks to be based on an antiferroelectric liquid crystalline materials (AFLC). The new group of materials consisting of a fluorinated terminal chain has been recently synthesized in Poland [1]. Such key factors as the optical indices, apparent tilt angle, and structural properties and electrooptical performance of these materials have been studied. The effect of the bend (hockey stick like) molecular shape has been assumed as a factor leading to an high apparent optical tilt angle. The relation between the apparent optical tilt angle and the tilt measured using XRD method and its change with the temperature has been explained.
