Abstract: The present invention provides a liquid crystal display device that is free from a reduction in the voltage holding ratio (VHR) of the liquid crystal layer and an increase in ion density (ID) and that enables problems of defective display, such as white spots, uneven alignment, and image-sticking, to be eliminated. In particular, the present invention provides a liquid crystal display device in which a liquid crystal composition containing a liquid crystal compound having a specific structure is used in the liquid crystal layer and in which an optically anisotropic body formed through polymerization of a polymerizable liquid crystal composition containing a specific amount of a polymerizable liquid crystal compound having a specific structure is used as an in-cell retardation layer.

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.

Also, an optically anisotropic body, a phase difference film, an antireflection film, and a liquid crystal display device, which are produced by using the polymerizable liquid crystal composition according to the present invention, are provided. The present invention is useful because three properties, that is, leveling properties of the surface of an optically anisotropic body, offset to a base material, and alignment properties of a liquid crystal can be improved at the same time in the case where the optically anisotropic body is produced by photopolymerizing the polymerizable liquid crystal composition.
