Abstract: The present invention relates to a liquid crystal display device including a specific liquid crystal composition and a sealant in which a cured product of a specific curable resin composition is used.The present invention provides a liquid crystal display device which prevents a decrease in the voltage holding ratio (VHR) of the liquid crystal layer and which enables elimination of problematic defective display such as voids, uneven alignment, and screen burn-in.Since the liquid crystal display device of the present invention prevents a decrease in the voltage holding ratio (VHR) of the liquid crystal layer and enables a reduction in defective display such as uneven alignment and screen burn-in, it is particularly useful for active-matrix liquid crystal display devices of a VA mode and PSVA mode and can be applied to liquid crystal display apparatuses such as liquid crystal TVs, monitors, mobile phones, and smartphones.
