Abstract

There is provided a compound containing a mesogenic group, which includes a silicon compound at a low concentration, a polymerizable compound containing the mesogenic group, a mixture and a composition using these compounds, a polymerizable mixture having the polymerizable compound, and a polymer, an optically anisotropic body, and a phase difference film using the polymerizable composition. It is possible to obtain the optically anisotropic body and the phase difference film having satisfactory scratch resistance and adhesion, by using the polymerizable composition composed of the compound containing a mesogenic group, which includes a silicon compound at a low concentration.
