Alignment Properties of Ferroelectric Liquid Crystals Using a Series of Polyimide Alignment Film.

Abstract

We have investigated a series of polyimides on alignment properties of ferroelectric liquid crystals. One of the properties of these polyimide alignment films is low-pretilt angle with nematic liquid crystals. These polyimide alignment films showed a high uniaxial orientation with the rubbing treatment. In this study, we discuss the relationship between the high uniaxial orientation of polyimide alignment film and the alignment of ferroelectric liquid crystals.
