Title:
【発明の名称】異方性化合物および液晶混合物
Document Type and Number:
Japanese Patent JP2714938
Kind Code:
B2
Abstract:
New anisotropic compounds of the formula (1) are useful in liquid crystal mixtures for electrooptical displays; at least one of the end groups of the compounds (1) is an alkyl group which carries cyano or halogen in a terminal or non-terminal position. This offers advantages for longitudinal polarization and/or cross-polarization of the anisotropic compounds with the aid of the comparatively highly polarizing cyano or halogen substituents, in particular high clear points, low DELTA epsilon / epsilon ORTHOGONAL values and/or negative DELTA epsilon values.
