The present invention relates to a liquid crystal display device that includes a particular liquid crystal composition and a color filter that uses a particular pigment. The present invention provides a liquid crystal display device that prevents a decrease in voltage holding ratio (VHR) and an increase in ion density (ID) in a liquid crystal layer and resolves the problems of display defects such as white streaks, alignment nonuniformity, and image sticking. Since the liquid crystal display device of the present invention prevents a decrease in voltage holding ratio (VHR) and an increase in ion density (ID) in the liquid crystal layer and resolves the problems of display defects such as image sticking, the liquid crystal display device is useful as VA-mode and PSVA-mode liquid crystal display devices of an active matrix drive type, and is applicable to liquid crystal display devices of liquid crystal televisions, monitors, cellular phones, smart phones, etc.
A liquid crystal display device comprising a first substrate, a second substrate, a liquid crystal composition layer held between the first substrate and the second substrate, a color filter that includes a black matrix and at least RGB three-color pixel portions, a pixel electrode, and a common electrode, the liquid crystal composition layer being constituted by a liquid crystal composition containing 30 to 50% of a compound represented by general formula (I)
