摘要:
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.
