Title:
LIQUID CRYSTAL COMPOSITION AND LIQUID CRYSTAL DISPLAY ELEMENT USING SAME
Document Type and Number:
WIPO Patent Application WO/2018/235713
Kind Code:
A1
Abstract:
Provided are: a liquid crystal composition containing at least one type of hindered amine-based light stabilizer having at least one unpaired electron in the molecules thereof; and a liquid crystal display element using said liquid crystal composition. This crystal composition is stable against heat and light, has a high specific resistance value, and has a high voltage holding ratio (VHR (UV)) after UV irradiation. In addition, a display element using this liquid crystal composition is extremely practical as a liquid crystal composition for liquid crystal displays and can provide excellent display quality having no display defects or suppressed display defects and fast response speed.
