Abstract:
An object of the present invention is to provide a polymerizable liquid crystal composition with which two characteristics of smoothness of a surface of an anisotropic optical body and orientation properties of liquid crystals can be simultaneously improved, when preparing an anisotropic optical body to be obtained by photopolymerization of the polymerizable liquid crystal composition. Specifically, an object of the present invention is to provide a polymerizable liquid crystal composition containing specific polymerizable compounds and a fluorine-based surfactant. In addition, an anisotropic optical body, a retardation film, an antireflective film, and a liquid crystal display element prepared using the polymerizable liquid crystal composition of the present invention are also provided.
