Abstract: The present invention provides a polymerizable composition containing a specific polymerizable compound and a fluorosurfactant having a specific polyoxyalkylene skeleton and having specific molecular weight. The invention also provides an optically anisotropic body, a retardation film, an antireflective film, and a liquid crystal display device that are produced using the polymerizable composition of the present invention. The present invention is useful because, when an optically anisotropic body is produced by photo-polymerization of the polymerizable composition, three features including the leveling properties of the surface of the optically anisotropic body, offset onto the substrate, and liquid crystal alignment can be improved simultaneously.

Abstract: The polymerizable composition prevents precipitation and the like of crystals and has high storage stability. A polymer compound is added to the polymerizable composition. In a case where a film-shaped polymer obtained by polymerizing the polymerizable composition is prepared, a tilt angle formed with an air interface is small, and glances of reflected light when a circularly polarizing plate is obtained by combining the polymer with a polarizing plate are removed. In addition, there is provided a polymer obtained by polymerizing the polymerizable composition, and an optically anisotropic body using the polymer. The polymerizable composition includes a reverse dispersible compound represented by General Formula (I), and a compound represented by General Formula (II).
