Title:
LIQUID CRYSTAL COMPOSITION AND LIQUID CRYSTAL DISPLAY ELEMENT
Document Type and Number:
WIPO Patent Application WO/2015/079797
Kind Code:
A1
Abstract:
Provided is a liquid crystal composition that satisfies at least one of the following characteristics, or that has a suitable balance between at least two of the following characteristics: a high upper-limit temperature of the nematic phase; a low lower-limit temperature of the nematic phase; low viscosity; suitable optical anisotropy; large negative dielectric anisotropy; large specific resistance; high stability against ultraviolet light; and high stability against heat. Also provided is an AM element having such characteristics as short response time, large voltage retention rate, low threshold voltage, large contrast ratio, and long life. Disclosed is a liquid crystal composition that comprises a compound contributing to high stability against heat or ultraviolet light, has negative dielectric anisotropy, and has a nematic phase, wherein the composition may comprise: a specific compound having large negative dielectric anisotropy as a first component; a specific compound having a high upper-limit temperature or a low viscosity as a second component; and a specific compound including a polymerizable group.
