Title:
LIQUID CRYSTAL DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/216483
Kind Code:
A1
Abstract:
The present invention pertains to a liquid crystal display device using a color filter which employs a specific liquid crystal composition, a specific pigment, and a specific compound. The present invention provides a liquid crystal display device that prevents a reduction in voltage holding rate (VHR) and an increase in ion density (ID) of a liquid crystal layer, and that solves the problem of display defects, such as voids, variations in orientation, and image persistence. Since the liquid crystal display device according to the present invention is characterized by being able to prevent a reduction in voltage holding rate (VHR) and an increase in ion density (ID) of a liquid crystal layer and to solve the problem of display defects, such as voids, variations in orientation, and image persistence; the liquid crystal display device is particularly useful for liquid crystal display devices of an ECB mode, VA mode, OCB mode, FFS mode, polymer-stabilizing IPS mode, IPS mode, and TN mode for driving an active-matrix, and is applicable to liquid crystal display devices for liquid crystal TVs, monitors, mobile phones, smart phones, etc.
