Title:
LIQUID CRYSTAL DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/128885
Kind Code:
A1
Abstract:
The present invention relates to a liquid crystal display device which employs a color filter that uses a specific liquid crystal composition and a specific pigment.
The present invention provides a liquid crystal display device which is prevented from a decrease in voltage holding ratio (VHR) of a liquid crystal layer and an increase in ion density (ID), thereby solving the problems of display failure such as white spot, alignment unevenness and image burn-in.
Since a liquid crystal display device of the present invention has such characteristics that a decrease in voltage holding ratio (VHR) of a liquid crystal layer and an increase in ion density (ID) are prevented and the occurrence of display failure such as image burn-in is suppressed, this liquid crystal display device is useful as an IPS mode or FFS mode liquid crystal display device for active matrix driving, and is applicable to liquid crystal display devices including a liquid crystal TV set, a monitor, a mobile phone and a smart phone.
