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.

Method for the preparation of photoaligning polymer materials and compositions

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.

Photo-alignable positive c-plate retarder

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.

Method for generating alignment on top of a liquid crystal polymer material

The invention relates to novel compositions comprising at least two anisotropic compounds of formula as well as to liquid crystalline networks, films and electro-optical devices comprising the compositions.

Compositions of polymerizable liquid crystals

The present invention relates to novel photoaligning polymer materials, to their use as orienting layer for liquid crystals, which are used for the production of non-structured and structured optical elements, electro-optical elements, multi-layer systems or in nanoelectronics.

Photoaligning polymer materials

The invention relates to encapsulation structures for OLED displays, wherein the structure provides sufficient barrier properties against oxygen and moisture as well as anti-reflection properties. The structure includes a layer comprising a photo-aligned substance which in a synergistic manner controls both barrier and anti-reflection properties.
