Abstract

An object of the present invention is to provide a polymerizable composition with which a polymer having a high degree of hardness can be produced. Another object is to provide, for example, an optically anisotropic body, a phase retardation film, an optical compensation film, an antireflection film, a lens, and a lens sheet that are composed of the polymerizable composition and a liquid crystal display element, an organic light-emitting display element, a lighting element, an optical component, a coloring agent, a security marker, a laser emission member, a polarizing film, a coloring material, and a printed item that are produced using the polymerizable composition. The present invention provides a polymerizable composition including a polymerizable compound represented by General Formula (IA) which has a specific structure including a plurality of polymerizable groups.
