Zusammenfassung:	The present invention relates to a liquid crystal display device employing a colour filter in which a specific liquid crystal composition, a specific pigment, and a specific compound are used. The present invention provides a liquid crystal display device which inhibits a reduction in the voltage holding ratio (VHR) of a liquid crystal layer, inhibits an increase in ion density (ID), and resolves problems related to display defects such as white spots, alignment unevenness, and burn-in. This liquid crystal display device is characterized in that a reduction in the voltage holding ratio (VHR) of the liquid crystal layer is inhibited, an increase in ion density (ID) is inhibited, and the occurrence of display defects such as burn-in is suppressed. Accordingly, the liquid crystal display device is particularly useful as an active-matrix-drive TN-mode, IPS-mode, polymer-stabilized IPS-mode, FFS-mode, OCB-mode, VA-mode, or ECB-mode liquid crystal display device. Furthermore, the liquid crystal display device is ap
