Title:
LIQUID CRYSTAL DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/013064
Kind Code:
A1
Abstract:
The present invention relates to a liquid crystal display device which uses a specific liquid crystal composition and a sealing agent using a cured product of a specific curable resin composition. The present invention provides a liquid crystal display device which prevents decrease in the voltage holding ratio (VHR) of a liquid crystal layer and increase in the ion density (ID), and which solves problems of display failure such as white spot, alignment unevenness and screen burn-in. Since a liquid crystal display device of the present invention is characterized by preventing decrease in the voltage holding ratio (VHR) of a liquid crystal layer and by suppressing the occurrence of display failure such as alignment unevenness and screen burn-in, this liquid crystal display device is useful as a liquid crystal display device of VA mode, PSVA mode, 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.
