Title:
LIQUID CRYSTAL COMPOSITION AND LIQUID CRYSTAL DISPLAY ELEMENT
Document Type and Number:
WIPO Patent Application WO/2010/044334
Kind Code:
A1
Abstract:
Disclosed is a liquid crystal composition which satisfies at least one of such characteristics as high upper limit temperature of the nematic phase, low lower limit temperature of the nematic phase, low viscosity, adequate optical anisotropy, large negative dielectric anisotropy, high resistivity, high stability against ultraviolet light and high stability against heat, or has an adequate balance between at least two of the above-mentioned characteristics. Also disclosed is an AM element having a short response time, high voltage holding ratio, high contrast ratio, long life and the like.
The liquid crystal composition contains a specific compound having tetrahydropyran-2,5-diyl as a first component, and a specific tetracyclic compound having a high upper limit temperature as a second component, and has a negative dielectric anisotropy. A liquid crystal display element contains the composition.
