Abstract
The best-known electrohydrodynamic instabilities in liquid crystals are the Williams domains.1 They are observed when an electric field is applied to a thin layer of a nematic liquid crystal having negative dielectric anisotropy and sufficient electrical conductivity. They manifest themselves as a set of parallel straight lines separated by a constant distance that is approximately equal to the cell thickness. They appear above a well-defined threshold voltage and exist in their original form over only a small voltage range. At higher voltages, the pattern becomes more complicated and leads to heavily scattering turbulence (dynamic scattering).2
