Abstract :
In nematic liquid-crystal layers with a π/2 twist, reverse twist disclination lines occur which can be pinned by surface features and moved by electric fields. We consider these effects as the basis of a bistable matrix display. The optical transmission through twisted regions of opposite chirality is analyzed using a Poincaré sphere construction.
