Nonlinear dielectric permittivities in the quiescent state and under shear flow ware measured in the isotropic and nematic phases of liquid crystal 5CB in rest state and. In the quiscent state nonlinear effects related to an electrode polarization ware observed in low-frequency region (below several ten Hz) in both the isotropic and the nematic phases with the effect in the nematic phase affected by its order. On the other hand, under shear flow larger and more clearer nonlinear effects ware observed. On the basis of these results, relationship between the nonlinear dielectric property and the nematic order will be discussed.
