摘要：

This paper shows that the dielectric anisotropy of conductivity in cells composed of nematic liquid crystal E7 ( NLC-E7) is related to the fact that the diffusion constant (D) is greater in a cell with homeotropic alignment than in one with homogeneous alignment (D-parallel to > D-perpendicular to). This behaviour can be understood by the study of the dielectric properties of the NLC based on the ionic hopping behaviour and on the analysis of the electrical conductivity in relation to the voltage applied.
