Estimating the term…
The instant invention relates to mesogenic compounds comprising a mesogenic group and one or more bulky end groups which each contain at least two ring elements, where two of these ring elements are linked to the C-atom No. 2 of a 1,3-dioxane-5-yl group by a direct bond or via a linking group, preferably the mesogenic group is linked to the C-atom No. 5 of the 1,3-dioxane-5-yl group and preferably the compounds are of formula I wherein the parameters are as specified in the text. This bulky end group preferably contains two or more rings, which each are bound to one and the same linking atom. The instant invention further relates to mesogenic media, preferably liquid crystal media showing a blue phase and their use in electro-optical light modulation elements and their respective use in displays, as well as to such devices.
