b) at least one photopolymerization initiator selected from the group consisting of alkylphenone-based compounds, acylphosphine oxide-based compounds, and oxime ester-based compounds; and c) a polymerization inhibitor. The present 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 liquid crystal composition. The polymerizable composition of the present invention is excellent in solubility and has high storage stability, so that no precipitation of crystals etc. occurs. When a film-shaped polymer is produced by polymerizing the above composition, the unevenness of the surface of the coating film is small while the alignment of the liquid crystal is maintained, and high durability is obtained. Therefore, the polymerizable composition is useful.
