Document Type and Number:
Japanese Patent JP6766556
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, high maximum temperature of a liquid-crystal phase, low minimum temperature thereof, small viscosity, suitable optical anisotropy, large dielectric anisotropy 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), a liquid crystal composition contains the compound and a liquid crystal display device includes the composition. In formula (1), Ra and Rb are fluorine or alkyl; A 0 , A 1 and A 2 are 1,4-phenylene; Z 1 and Z 2 are a single bond or alkylene; one of Y 1 and Y 2 is fluorine, and the other is hydrogen; Rc is alkyl; and a and b are independently 0, 1, 2 or 3, and a sum of a and b is 0, 1, 2 or 3.
