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 suppressing the occurrence of display defects such as image sticking and the like. The liquid crystal display device is thus useful for a VA-mode or PSVA-mode liquid crystal display device for active matrix driving. The application of the device includes liquid crystal display devices such as liquid crystal TVs, monitors, cellular phones, and smart phones.
