Layer Thickness Dependence of Steady State Current in Nematic Liquid Crystal

Abstract

Steady state current of nematic liquid crystal cells has been measured. The experimental results show that there is no thickness dependence for the sample cell using no aligning layer; and for the sample cell using poly-imide aligning layer, current depends on cell thickness: thicker rigion, current is proportional to inverse of thickness, and thinner rigion, proportional to quadratic of thickness.
