Title:
ANISOTROPIC COMPOUND AND LIQUID CRYSTAL MIXTURE
Document Type and Number:
Japanese Patent JPS6084232
Kind Code:
A
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.
