Abstract

The instant invention relates to mesogenic compounds which comprise a phenyl ring, which is bearing two mesogenic groups in otho position to each other, preferably of formula I, wherein the parameters are as specified in the text. 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.
