Title:
LIQUID CRYSTAL COMPOSITION AND LIQUID CRYSTAL DISPLAY ELEMENT
Document Type and Number:
WIPO Patent Application WO/2011/099400
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, large optical anisotropy, large dielectric anisotropy, high resistivity, high elastic constant, high stability with respect to ultraviolet light and high stability with respect to heat, or which has an adequate balance among at least two of the above-mentioned characteristics. Also disclosed is an AM element which has a short response time, high voltage holding ratio, high contrast ratio, long life and the like. The liquid crystal composition has a nematic phase and contains a specific tetracyclic compound having a high upper limit temperature and a large optical anisotropy as a first component, and a specific compound having a high upper limit temperature and a large dielectric anisotropy as a second component. The liquid crystal display element contains the composition.
