ABSTRACT:
Reflective liquid crystalline polymer films having increased bandwidth have a single layer of liquid crystalline material with short, long, and medium pitch of the helical molecular structure of the liquid crystalline polymer. The films are easily produced by a readily reproducible and economic process of low complexity.
