  • Liquid crystalline electrooptical device
    Patent number: 5543950
    Abstract: An electrooptical light modulating device includes a liquid crystalline material disposed between first and second opposing cell wall structures and comprising liquid crystal of positive dielectric anisotropy. The first cell wall structure is treated with a first aligning material to homeotropically align liquid crystal molecules of the material and the second cell wall structure is treated with a second aligning material that is different from the first aligning material to homeotropically align liquid crystal molecules of the material, whereby the liquid crystal exhibits a unipolar electrooptic effect in the presence of an electric field.
