  The present invention provides a liquid crystal display device which can prevent a decrease in a voltage holding ratio (VHR) of a liquid crystal layer and an increase in ion density (ID) and solve a problem of a display defect such as white spots, alignment irregularities, burn-in, or the like. The present-invention provides a liquid crystal display device which uses a liquid crystal composition containing a liquid crystal compound having a specific structure as a liquid crystal layer, and an optically anisotropic body obtained by polymerizing a polymerizable liquid crystal composition containing a polymerizable liquid crystal compound having a specific structure at a specific ratio as an in-cell type retardation film. Since the liquid crystal display device of the present-invention can prevent a decrease in a voltage holding ratio (VHR) of a liquid crystal layer and an increase in ion density (ID) and suppress the occurrence of a display defect, such as burn-in or the like, the liquid crystal display device of the present invention is useful particularly for an active matrix driving VA mode or PSVA mode liquid crystal display device, and can be applied to liquid crystal display devices such as liquid crystal televisions, monitors, mobile phones, smart phones, or the like.

  The present invention provides a mixture including a compound that has a mesogenic group and satisfying an expression represented by Expression (1): 1.0≦ YI/Δn ≦50.0  Expression (1) wherein YI represents a yellowness index of the mixture and Δn represents a refractive index anisotropy of the compound having a mesogenic group. In a case of producing an optical anisotropic body constituted by a composition prepared by using the compound, repellence hardly occurs, and the mixture exhibits excellent alignment properties in a case of using the optical anisotropic body. Furthermore, a composition that contains the mixture and an optical anisotropic body that uses the composition are provided.

  The invention provides a polymerizable composition including a compound that has a mesogenic group and satisfying an expression represented by Expression (1): 1.0≦YI/Δn≦50.0, wherein YI represents a yellowness index of a material including only a compound having a mesogenic group in the polymerizable composition, and Δn represents a refractive index anisotropy of a material including only a compound having a mesogenic group in the polymerizable composition, with the proviso that a chiral compound having a mesogenic group is excluded in the material including only the compound having the mesogenic group. The polymerizable composition has high storage stability and is unlikely to cause an increase of the content of a polymer component when being added to a polymerizable liquid crystal composition, and is excellent in adhesiveness, is not unlikely to cause discoloration, and exhibits good coating properties and good alignment properties in preparing an optical anisotropic body.
