Abstract
There is provided a polymerizable liquid crystal composition that enables a film formed through application of the composition and exposure thereof to heat or active energy rays to have an excellent molecular alignment and reduced haze. There is also provided an optically anisotropic body that is produced by using such a polymerizable liquid crystal composition and that has a good transparency. In particular, the present invention provides a polymerizable liquid crystal composition containing a polymerizable haze-reducing agent and a polymerizable liquid crystal compound. Furthermore, the present invention also provides an optically anisotropic body produced by using the polymerizable liquid crystal composition of the present invention. Using the polymerizable liquid crystal composition of the present invention enables production of an optically anisotropic body having a good transparency; hence, the polymerizable liquid crystal composition is usefully applied to optical materials used in, for example, retardation films.
