Abstract
A dual frequency liquid crystal may be stabilized in the blue phase by a polymer matrix to provide an improved blue phase temperature range having a magnitude of at least about 65° C. Polymer-stabilized, blue phase dual frequency liquid crystal compositions and methods for producing polymer-stabilized, blue phase dual frequency liquid crystals are disclosed.
