摘要： A liquid-crystal (LC) material having negative dielectric anisotropy and the use thereof for optical, electro-optical and electronic purposes, such as for example in LC displays, in particular energy saving displays based on the ECB, IPS or FFS effect, where the liquid crystal medium contains one or more compounds of formula I




and one or more compounds compounds of formulae IIA, IIB, IIC and IID

摘要： A liquid-crystal (LC) medium which is based on a mixture of polar compounds and is substantially dielectrically neutral, its use for optical, electro-optical and electronic purposes, in particular as optical retarder or optical compensator in LC displays, an optical retarder or optical compensator containing the LC medium, an optical, electrooptical or electronic device containing the optical retarder or optical compensator, and a process of manufacturing the optical retarder or optical compensator.
