The invention relates to a liquid crystal mixture characterised in that it comprises one or more photoreactive mesogens of formula I wherein the parameters and groups occurring are defined as indicated in claim, to a process for the fabrication of liquid crystal displays using these liquid crystal mixtures and to a liquid crystal display obtainable by this process. The invention further relates to new compounds of formula I.

Liquid crystal mixture and liquid crystal display

The invention relates to a method of manufacturing a liquid crystal display device wherein a liquid crystal mixture having positive dielectric anisotropy or negative dielectric anisotropy is interposed between a first substrate and a second substrate, the liquid crystal mixture comprising liquid crystal molecules, a self assembling photoalignment agent, a polymerisable compound, and wherein said LC mixture is photoaligned by irradiation with linearly polarised ultraviolet light and then cured by irradiation with ultraviolet light.

Method for manufacturing a liquid crystal display device and liquid crystal mixture

The invention relates to cinnamic acid derivatives of formula S wherein the radicals have the meaning indicated in claimto a process for their preparation and their use as self assembling photoalignment agent in liquid crystal mixtures. The invention further relates to a process for the fabrication of a liquid crystal (LC) display device with homogeneous alignment by photoaligning a liquid crystal mixture with positive or negative dielectric anisotropy comprising one or more compounds of formula S and optionally a polymerizable compound, to the liquid crystal mixture comprising the self assembling photoaligning agent and optionally the polymerizable compound and to the LC display produced by said process.
