Abstract
We discuss the role of the Miesowicz viscosities on director reorientation in pi-cells, showing that the symmetry of this system allows for a simplifi cation of the dynamical equations. We consider practical aspects of materia l optimisation for increased pi- cell switching speed. We make an observati on regarding the switching speeds of positive and negative dielectric aniso tropy surface mode devices.
