摘要：
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.
