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 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: An object of the present invention is to provide a powder mixture containing a polymerizable liquid crystal compound, the powder mixture having a low risk of occurrence of fire due to the flammability of solvent, causing no changes in the appearance due to, for example, precipitation or crystallization of the solute during storage at low temperatures, causing no changes in the composition due to evaporation of solvent during long-term storage or leakage of solvent during long-term storage or transportation, being not viscous and having fluidity unlike nematic liquid crystal compositions, and being easily handled. Another object is to provide a nematic liquid crystal composition, a solution composition, cured products, optical films, and display devices that employ the above-described powder mixture.
