Abstract
We have observed the behaviour of chiral nematic droplets with positive dielectric anisotropy subjected to electric fields. With increasing field, the Frank-Pryce spherulitic director configuration is distorted progressively into a quasi-cylindrical spiral twist wall. As the field increases further this wall progressively unwinds, resulting in a confined cholesteric-nematic transition. Measurements of the pitch versus electric field show that, despite the confinement, the pitch is still described by the theory for the unconfined cholesteric-nematic transition.
