LIQUID CRYSTAL MIXTURES, IN PARTICULAR FERROELECTRIC LIQUID CRYSTAL MIXTURES

摘要

- 45 - HOE 89/F 095 Liquid-crystalline mixtures in particular ferroelectric liquid-crystalline mixtures The novel liquid-crystalline mixtures (in the case of ferroelectric behavior they additionally contain an optically active compound as dope) are based on at least two mixture components of the general formula (I) and at least one carboxylate of the general formulae ¢sic! (II), (III) or (IV). (I) (II) X = O or a single bond (III) (IV) The mixtures have favorable properties for use in electrooptical display elements, such as high contrast, low melting point and short switching times.
