Encapsulated operationally nematic liquid crystal is contained in plural volumes formed by a containment medium. The volume walls tend to distort the natural structure of the liquid crystal in the absence of a prescribed input, such as an electric field; the liquid crystal structure tends to align in parallel in the presence of such prescribed input. An additive, for example a chiral additive, in the liquid crystal tends to expedite return to distorted alignment upon removal of the prescribed input. Moreover, an additive can be employed to cause the liquid crystal structure near the wall of the containment medium to be oriented approximately normal to the wall when in distorted or random alignment in the absence of the prescribed input.
