Patent abstract
A method for the manufacture of a polarizer is provided. The method comprises providing a liquid crystal composition comprising a liquid crystal host and a viscosity enhancer; providing a thin film of said composition on a substrate; orienting said liquid crystal host to obtain an aligned film in a first liquid crystal mesophase, wherein the liquid crystal host is aligned planar to said substrate; gelating said viscosity enhancer to congeal said film; and obtaining a second liquid crystal state in said congealed film. By the use of a viscosity enhancer in the composition, homeotropic alignment of the liquid crystal host can be suppressed.
