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: SUMMARY
The present invention relates to a method for manufacturing a spatially limited film stack comprising an optically anisotropic film on an optical sensor device with a light sensor element, such that the film stack covers the light sensor element but not the entire surface area of the optical sensor device. An electronic device manufactured according to the method of the invention can be used for analyzing the polarization state of 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.
