  • Multistable reflective liquid crystal device
    Patent number: 9280018
    Abstract: A multistable liquid crystal device having liquid crystal molecules in one or more cavities, wherein at least one liquid crystal region of high distortion (100, 110) is formed in each cavity, the distortion region (100, 110) being switchable between at least two stable states on application of an electric field, the device being such that at least one of the stable states may be utilized as a reflective mode.
    Type: Grant
