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: Optical elements with anisotropic, patterned surface relief microstructures in which information is encoded in the distribution of the orientation of different zones. From the analysis of the distribution of the light scattered from the element, the orientation distribution in the element and therefore the encoded information can be evaluated. The elements are particularly useful for securing documents and articles against counterfeiting and falsification.

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.

Abstract: The present invention relates to a novel method for the preparation of photoaligning polymer materials comprising aryl acrylic acid ester groups, to photoalignment compositions obtained by this process, to the use of the composition as orienting layer for liquid crystals and to non-structured and structured optical elements, electro-optical elements, multi-layer systems or in nanoelectronics comprising the compositions.
