Abstract
An in-plane retardation switching device includes a first substrate, a second substrate, a non-chiral smectic C phase liquid crystal material disposed between the first substrate and the second substrate. The liquid crystal material is of a bulk state. The liquid crystal material has a phase transition sequence of a smectic C phase, a smectic A phase, a nematic phase and an isotropic phase in this order. The liquid crystal material does not have spontaneous polarization and is configured to be driven by quadra-pole momentum of the liquid crystal material.
