Abstract: The present invention provides a liquid crystal display device capable of preventing a decrease in voltage holding ratio (VHR) of a liquid crystal layer and an increase in ion density (ID) and resolving the problem of display defects such as white spots, alignment unevenness, image sticking, and the like. The liquid crystal display device of the present invention is characterized by preventing a decrease in voltage holding ratio (VHR) of a liquid crystal layer and an increase in ion density (ID) and suppressing the occurrence of display defects such as image sticking and the like, and is thus particularly useful for a VA-mode or PSVA-mode liquid crystal display device for active matrix driving, and can be applied to liquid crystal display devices such as a liquid crystal TV, a monitor, a cellular phone, a smart phone, and the like.
