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.

Abstract: The present invention relates to material compositions and methods for generating photo-alignable positive c-plate retarders. Because a planar alignment direction can be induced in the surface of the above c-plate retarder by exposure to polarized light, a slave material can be aligned on the surface of the c-plate retarder with a defined azimuthal orientation direction, without the need of an additional orientation layer.
