| 摘要 |
The invention provides a polymerizable compound having a suitable polymerization reactivity, a high conversion yield and a high solubility in a liquid crystal composition. It provides a liquid crystal composition having physical properties such as a high maximum temperature of a nematic phase, a low minimum temperature of a nematic phase, a small viscosity, a suitable optical anisotropy, a large dielectric anisotropy, a suitable elastic constant, a large specific resistance and a suitable pretilt. The compound represented by formula (1).
For example, the rings A 1 , A 2 , A 3 and A 4 are 1,4-phenylene, Z 1 and Z 2 are alkylene having 1 to 10 carbons in which at least one -CH 2 -may be replaced by -0- or -CH=CH-; L 1 , L 2 and L 3 are a single bond, -COO- or -CH=CH-; G 1 and G 2 area single bond or -0-; s, t and u are 0 or 1; and P 1 and P 2 is the group (P-1), the group (P-2) or the group (P-3).
M 1 and M 2 are hydrogen or methyl. |
