LIQUID CRYSTAL DISPLAY DEVICE

WIPO Patent Application WO/2015/097740

A1

The present invention relates to a liquid crystal display device which uses a color filter having a specific slope parameter that indicates a specific agglomeration degree of a liquid crystal composition and an organic pigment. The present invention provides a liquid crystal display device which is prevented from a decrease in the voltage holding ratio (VHR) of a liquid crystal layer and an increase in the ion density (ID), and which solves display failure problems such as white spots, alignment unevenness and image burn-in. Since a liquid crystal display device of the present invention is characterized by being prevented from a decrease in the voltage holding ratio (VHR) of a liquid crystal layer and an increase in the ion density (ID) and by suppressing the occurrence of display failure such as image burn-in, this liquid crystal display device is useful especially for liquid crystal display devices of IPS mode and FFS mode for active matrix driving, and is applicable to liquid crystal display devices such as a liquid crystal TV, a monitor, a mobile phone and a smart phone.
