Document Type and Number:
Japanese Patent JP6738046
Kind Code:
B2
Abstract:
Provided are a liquid crystal compound satisfying at least one of physical properties such as high stability to heat or light, a high clearing point (or high maximum temperature) , low minimum temperature of a liquid crystal phase, small viscosity, large optical anisotropy, large negative dielectric anisotropy, a suitable elastic constant and good compatibility with other liquid crystal compounds, a liquid crystal composition containing the compound and a liquid crystal display device including the composition. A compound is represented by formula (1):
wherein, R 1 and R 2 are alkyl having 1 to 15 carbons; A 1 , A 2 , A 3 and A 4 are 1, 4-cyclohexylene and 1, 4-phenylene; Z 1 , Z 2 , Z 3 and Z 4 are a single bond; Y 1 , Y 2 and Y 3 are fluorine; and a, b, c and d are 0 or 1, and a sum of a, b, c and d is an integer from 0 to 3, or the like.
