This paper reviews the current development of the PDLC technology. The original PDLC films using isotropic binders have been substituted by anisotropic binders for the purpose of indices match between the low molecular weight liquid crystals and the binders. A wide- viewing-angle light shutter was produced using a side-chain liquid crystalline epoxy polymer as binder. Recently, a new type of polymer-stabilized cholesteric liquid crystal dispersion (PSCLCD) containing less than 5 wt% of the binder in the dispersion systems was developed. Three different operation modes of cell devices were obtained at zero field: normal-mode, reverse-mode and bistable mode.
