Patent number: RE36849Abstract: Anisotropic compounds of the formula (1) specified in claim 1 are suitable, owing to their low .DELTA..epsilon./.epsilon..perp. values for liquid crystal displays which have high information densities of for examples up to 10.sup.6 image dots and accordingly need to be highly multiplexible; compared with known compounds they offer improved application properties and are relatively simple to synthesize.Type: GrantFiled: April 1, 1993Date of Patent: September 5, 2000Assignee: Merck Patent GmbHInventors: Hans P. Schad, Stephen M. Kelly, Eike Poetsch, Reinhard Hittich, Georg Weber
