Abstract: There is provided a liquid crystal display device that may limit a reduction in the voltage holding ratio (VHR) of a liquid crystal layer and an increase in the ion density (ID) in the liquid crystal layer and thereby address issues of faulty display such as white missing pixels, alignment inconsistencies, and burn-in. The liquid crystal display device according to the present invention, which may limit a reduction in the voltage holding ratio (VHR) of a liquid crystal layer and an increase in the ion density (ID) in the liquid crystal layer and thereby reduce the risk of faulty display such as burn-in, can be suitably used, in particular, as an IPS-mode or FFS-mode liquid crystal display device for active-matrix driving and may also be used as a liquid crystal display device for liquid crystal display televisions, monitors, mobile phones, smart phones, or the like.

Abstract: The present invention relates to a liquid crystal display device that uses 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) of a liquid crystal layer and resolves the problems of display defects, such as missing dots, alignment variation, and ghosting. 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) of a liquid crystal layer and resolves the problems of display defects, such as ghosting, it is particularly useful for active matrix drive VA-mode and PSVA-mode liquid crystal display devices and can be applied to liquid crystal display devices such as liquid crystal televisions, monitors, cellular phones, and smart phones.
