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.
