Abstract
An object of the invention is to provide a liquid crystal composition intended to be applied to the surface of a base material to form a phase difference layer, the liquid crystal composition being capable of forming a phase difference layer well indicating homeotropic orientation without the presence of an oriented film, even if the liquid crystal composition is directly applied to the base material surface, as well as a phase difference layer formed by the liquid crystal composition, a color filter and a liquid crystal display apparatus using the phase difference layer, and further a method of forming the phase difference layer. To a liquid crystal composition containing one kind or two or more kinds of crosslinking liquid crystal compounds is further added at least an amino-based silane coupling agent to prepare a liquid crystal composition. The liquid crystal composition is directly applied to the surface of a base material to orient the crosslinking liquid crystal compound on the base material surface in a direction perpendicular to the base material surface, and then the resulting material is crosslinking polymerized to form a phase difference layer.
