Paragraph 0171-0180, (2018/02/03)
In light of requests to reduce or reverse the wavelength dispersion of the birefringence of a phase-retardation film in order to increase the viewing angle of a liquid crystal display, the present invention provides a polymerizable compound that reduces, for example, the likelihood of crystals precipitating in a polymerizable composition including the polymerizable compound and enables the polymerizable composition to have high preservation stability and a polymerizable composition including the polymerizable compound which reduces the likelihood of inconsistencies being formed in a film-like polymer produced by polymerizing the polymerizable composition. Another object of the present invention is to provide a polymer produced by polymerizing the polymerizable composition and an optically anisotropic body including the polymer.
