A liquid crystal display device which prevents a decrease in the voltage holding ratio (VHR) of a liquid crystal layer and an increase in ion density (ID) therein and which overcomes problems of defective display such as voids, uneven alignment, and screen burn-in. The liquid crystal display device prevents a decrease in the voltage holding ratio (VHR) of a liquid crystal layer and an increase in ion density (ID) therein and reduces defective display such as screen burn-in; hence, such a liquid crystal display device is particularly useful as liquid crystal display devices of a VA mode and PSVA mode which involve active matrix driving and can be applied to the liquid crystal display devices of liquid crystal TV sets, monitors, mobile phones, and smartphones.

Liquid Crystal Display Device

A liquid crystal display device that prevents a decrease in the voltage holding ratio (VHR) and an increase in the ion density (ID) in a liquid crystal layer and that resolves the problems of display defects, such as white streaks, variations in alignment, and image sticking. The liquid crystal display has features of preventing a decrease in the voltage holding ratio (VHR) and an increase in the ion density (ID) in a liquid crystal layer and suppressing display defects such as image sticking. Therefore, the liquid crystal display device is particularly useful for active matrix driving liquid crystal display devices with an IPS mode or an FFS mode and can be applied to liquid crystal display devices of, for example, liquid crystal televisions, monitors, cellular phones, and smart phones.
