  • METHOD FOR GENERATING ALIGNMENT ON TOP OF A LIQUID CRYSTAL POLYMER MATERIAL
    Publication number: 20220035086
    Abstract: The present invention relates to a method for manufacturing an optical element including a layer comprising anisotropic optical function and alignment capability. The layer is formed from a composition comprising polymerizable liquid crystals and one or more photo-orientable substances. Alignment on top of the layer is achieved by exposure to linearly polarized light.
    Type: Application
