The present invention relates to a liquid crystal display device using a color filter using a specific liquid crystal composition, a specific pigment, and a specific compound.n n n The invention provides a liquid crystal display device which prevents a decrease in voltage holding rate (VHR) and an increase in ion density (ID) of a liquid crystal layer, and solves problems of poor display such as whitening, uneven alignment, and residual image.n n n The liquid crystal display device of the present invention is characterized in that it prevents a decrease in the voltage holding ratio (VHR) of the liquid crystal layer, an increase in the ion density (ID), and suppresses the occurrence of display defects such as afterimages. Therefore, it is particularly suitable for the TN mode for active matrix driving. , IPS mode, polymer stabilized IPS mode, FFS mode, OCB mode, VA mode, or ECB mode are useful for liquid crystal display devices, and can be applied to liquid crystal display devices such as LCD TVs, monitors, mobile phones, and smart phones . |
