  • Cholesteric liquid crystal optical bodies and methods of manufacture
    Patent number: 6573963
    Abstract: An optical body can be formed using cholesteric liquid crystal materials. At least two different coating compositions containing cholesteric liquid crystal material are coated on a substrate. At least a portion of each composition is allowed to interdiffuse to generate a change in pitch along a thickness dimension of the optical body. This optical body can be used, for example, as a reflective polarizer in an optical display.
    Type: Grant
