Abstract The rise and decay times of a Fréedericksz deformation in a planar nematic layer have been investigated. The liquid crystal used was an ester mixture with regimes of positive as well as negative dielectric anisotropy. This property allows to control both the rise and the decay times of the deformation by switching the frequency of the electric field. The kinetics was monitored with a fluorescent dye-probe.
