Electrical Properties of Liquid-Crystal Materials for Display Applications

Abstract

ABSTRACTBoth dielectric permittivity and AC conductivity are important properties of LC materials for use in displays. By taking typical LC substances as examples, quantitative data are presented on these properties. From microscopic point of view, permanent dipole of LC molecules and ions contained in LC materials play important roles in these electric properties. Quantitative discussions are also presented on these microscopic characteristics. Theoretical understandings of these properties are reviewed, providing good explanations of the relation between these microscopic and macroscopic properties.
