Flexible liquid crystal display device with improved mechanical ability

摘要

The liquid crystal display has a liquid crystal cell (15) containing a bistable ferroelectric liquid crystal (12). The liquid crystal cell (15) is a quarter wave cell and includes two opposing covering electrodes (13) arranged in a flexible, preferably plastic, substrate (11) on opposite sides of the bistable ferroelectric liquide crystal (12) and spacers (16) distributed between the covering electrodes (13). A diffuser or reflector (18) is arranged on a rear side of the substrate (11) so that light passes twice through the liquid crystal cell (15). 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 (14) for the liquid crystal are applied obliquely or diagonally to the surface of the substrate.
