Abstract
The liquid crystal display has a liquid crystal cell ( ) containing a bistable ferroelectric liquid crystal ( ). The liquid crystal cell ( ) is a quarter wave cell and includes two opposing covering electrodes ( ) arranged in a flexible, preferably plastic, substrate ( ) on opposite sides of the bistable ferroelectric liquide crystal ( ) and spacers ( ) distributed between the covering electrodes ( ). A diffuser or reflector ( ) is arranged on a rear side of the substrate ( ) so that light passes twice through the liquid crystal cell ( ). The bistable liquid crystal display with the quarter wave liquid crystal cell is flexible but mechanically stable to mechanical impacts, torsion and bending. Orienting layers ( ) for the liquid crystal are applied obliquely or diagonally to the surface of the substrate.
