The invention relates to a method of preparing a polymer film and to the use of such polymer film as in liquid crystal displays (LCDs) or other optical or electrooptical devices, for decorative or security applications, as alignment layer or optical retardation film.

Method of preparing a birefringent polymer film

The invention relates to a method of preparing a polymer film and to the use of such polymer film as in liquid crystal displays (LCDs) or other optical or electro optical devices, for decorative or security applications, as alignment layer or optical retardation film.

The invention relates to an optically biaxial film comprising an anisotropic material with deformed helically twisted structure and locally varying birefringence, to methods and materials for its preparation, to its uses as retardation or compensation film in optical devices like liquid crystal displays, and to compensators and liquid crystal displays comprising such a biaxial film.

Biaxial film having local birefringence that varies periodically

The invention relates to a polymerisable liquid crystal (LC) material, to optically biaxial films prepared thereof, to novel polymerisable compounds used therein and to the use of the material and films in optical devices like compensators and LC displays (LCDs).

Polymerisable liquid crystal material

The invention relates to an optically biaxial film with cholesteric structure, methods and materials for its preparation, its use as retardation or compensation film in optical devices like liquid crystal displays, and to compensators and liquid crystal displays comprising such a biaxial retardation film.

Biaxial film

The invention relates to a negative birefringent retardation film comprising polymerised liquid crystal (LC) material with helically twisted structure and planar orientation, its use in compensators and electrooptical displays like liquid crystal displays, and to compensators and liquid crystal displays comprising such a negative retardation film.

Negative retardation film

The invention relates to a compensator comprising a positive and a negative birefringent retardation film, its use in displays and optical elements, and to displays comprising such a compensator.

Compensator comprising a positive and negative birefringent retardation film
