Abstract
There is provided 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 prevents a decrease in voltage holding ratio (VHR) of a liquid crystal layer and an increase in ion density (ID) and suppresses the occurrence of display defects such as image sticking, and the like. The liquid crystal display device is useful for an IPS-mode or FES-mode liquid crystal display device for active matrix driving. The application of the device can include liquid crystal TVs, monitors, cellular phones, smart phones, and the like.
