The present invention provides a polymerizable composition containing a specific polymerizable compound and a fluorosurfactant having, in its molecule, a pentaerythritol skeleton or a dipentaerythritol skeleton. 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.
