Title:
LIQUID CRYSTALLINE COMPOUND, LIQUID CRYSTAL COMPOSITION AND LIQUID CRYSTAL DISPLAY ELEMENT
Document Type and Number:
Japanese Patent JP2012176933
Kind Code:
A
Abstract:

To provide a liquid crystalline compound having high stability to heat, light or the like, a wide temperature range of a nematic phase, low viscosity, appropriate optical anisotropy, and a large elastic constant K33, and negatively large dielectric anisotropy and excellent compatibility with other liquid crystalline compounds, also to provide a liquid crystal composition having characteristics similar to these of the compound, and further to provide a liquid crystal display element having a short response time, low electric power consumption, a low driving voltage, a large contrast ratio, and usable in a wide temperature range.

The compound is a 2,3-difluorobenzene derivative (1) having a combination of a cyclohexane ring, a cyclohexene ring or a benzene ring and a butene bonding group. The liquid crystal composition contains the compound, and the liquid crystal display element contains the composition.
