ABSTRACT:
A device composed of: (a) a first liquid crystal composition including a first liquid crystal and a first liquid crystal domain stabilizing compound, wherein the first liquid crystal composition switches between a strongly scattering state of a first plurality of smaller liquid crystal domains that strongly scatters a predetermined light and a weakly scattering state of a second plurality of larger liquid crystal domains that weakly scatters the predetermined light; and (b) a second liquid crystal composition including a second liquid crystal and a second liquid crystal domain stabilizing compound, wherein the second liquid crystal composition switches between a strongly scattering state of a first plurality of smaller liquid crystal domains that strongly scatters the predetermined light and a weakly scattering state of a second plurality of larger liquid crystal domains that weakly scatters the predetermined light, wherein the second liquid crystal composition and the first liquid crystal composition are in a stacked arrangement.
