    摘要: Electrooptical liquid crystal system [sic] containing nematic microdroplets which are embedded in a transparent matrix and consist of a liquid crystal mixture, characterized in that, to increase the flow viscosity to values >40 mm.sup.2 /s at 20.degree. C., the liquid crystal mixture contains one or more side-chain polymers containing monomer units of the formula I ##STR1## wherein P is a main polymer chain unit,Sp is an alkylene group having 1-20 C atoms, wherein one or more non-adjacent CH.sub.2 groups can also be replaced by --O--, --S-- and/or --NR.sup.2 --, andB is an organic "rod-like" radical,can be used for the preparation of large-area display systems, in particular those operating with alternating voltage.
