The instant invention relates to mesogenic systems comprising a) a polymeric component, component A, obtained or obtainable from polymerisation of a precursor comprising one or more mesogenic mono-reactive compounds, one or more di-reactive compounds, which optionally are also mesogenic compounds and optionally a photo-initiator and a low molecular weight component, component B, comprising one or more mono-reactive, mesogenic compounds, one or more mesogenic compounds and one or more chiral dopants, exhibiting a Blue Phase, as well as to the use of these systems in deices and to these devices.

Liquid crystal system and liquid crystal display

The instant invention relates to mesogenic systems comprising a) a polymeric component, component A, obtained or obtainable from polymerization of a precursor comprising one or more mesogenic mono-reactive compounds, one or more di-reactive compounds, which optionally are also mesogenic compounds and optionally a photo-initiator and a low molecular weight component, component B, comprising one or more mono-reactive, mesogenic compounds, one or more mesogenic compounds and one or more chiral dopants, exhibiting a Blue Phase, as well as to the use of these systems in deices and to these devices.

The present invention relates to a liquid crystalline mixture comprising   A, Z, A, L, L, X, m and n have the meanings given in claimand their use in TFT, TN, IPS applications and expecially for devices utilizing electro-optical effects in an optically isotropic state.

Liquid crystalline medium

The invention is directed to the use of a liquid crystal composition in a bistable liquid crystal device and especially in a zenithal bistable nematic liquid crystal device, a nematic liquid crystal medium, and a bistable liquid crystal device comprising the liquid crystal composition whereby said liquid crystal composition comprises at least 30 weight % (based on the total weight of the composition) of a component (&#x3b1;) containing one or more compounds having a dielectric anisotropy &#x394;&#x3b5; of at least 25, whereby at least 25 weight % (based on the total weight of the composition) of said compounds have a dielectric anisotropy &#x394;&#x3b5; of at least 40; and at least 5 weight % of a component (&#x3b2;).
