The present invention relates to a liquid crystal display device including a particular liquid crystal composition and a cured product of a particular curable resin composition serving as a sealant. The present invention provides a liquid crystal display device that does not suffer from a decrease in the voltage holding ratio (VHR) or increase in the ion density (ID) of the liquid crystal layer or the problem of display defects such as white spots, alignment unevenness, and image-sticking. Since the liquid crystal display device according to the present invention does not suffer from a decrease in the voltage holding ratio (VHR) of the liquid crystal layer or display defects such as alignment unevenness and image-sticking, the liquid crystal display device is particularly useful as an active-matrix-driven liquid crystal display device such as a VA, PSVA, IPS, or FFS liquid crystal display device and can be used as a liquid crystal display device for products such as liquid crystal display televisions, monitors, cell phones, and smartphones.
