The present invention further relates to a process for the fabrication such liquid crystal display and to the use of the liquid crystal mixtures according to the invention for the fabrication of such liquid crystal display.

Liquid crystal mixture and liquid crystal display

A double layer liquid crystal device comprises a first and a second layer with orthogonal or crossed alignment of the liquid crystal phase of the two layers, in which the first and second layer have first and second alignment aids comprised of a polymerized or polymerizable molecular compound. The layers are aligned by UV photoalignment and vertical self-alignment by the aid of suitable additives.

Double layer liquid crystal device and process of manufacture

The invention relates to a medium comprising at least 60% of one or more compounds of formula I wherein R, R, MG, MGand Sphave the meaning given herein below, to the use of such media in liquid crystal devices, in particular in flexoelectric liquid crystal devices, and to a flexoelectric liquid crystal device comprising a liquid crystal medium according to the present invention.

Liquid crystal medium and liquid crystal device

The present invention relates to a process of preparing a light modulation element of the PS-ULH (polymer stabilised ULH) type, which allows to reduce the operational voltage and allows to improve the switching time of the light modulation element.

Process of preparing a light modulation element

The invention provides a light modulation element comprising a flexoelectric polarisable liquid-crystalline medium, characterized in that the switching from a boundary state A to a boundary state B comprises a combination of a distinct flexoelectric switching regime and a distinct dielectric switching regime upon application of an electric field.
