ABSTRACT:
A single substrate polymeric cholesteric liquid crystal (CLC) device useful in display applications such as for high efficiency polarizers and color filters is created by a process that coats a first substrate with a polyimide layer and a second substrate with an amorphous fluoropolymer layer. Both layers are buffed and liquid CLC material is placed between the grooved layers. After annealing, the amorphous fluoropolymer coated substrate is removed, leaving the CLC material bonded to a single substrate.
