Document Type and Number:
Japanese Patent JP4655387
Kind Code:
B2
Abstract:
Silicon compounds having a low viscosity and a low threshold voltage and improved mutual solubility, a liquid crystal composition comprising the same and a liquid crystal display using the liquid crystal composition. The silicon compound is represented by formula (1):wherein Y<1 >is, for example, alkylene having 1 to 10 carbon atoms, Y<2 >is, for example, hydrogen, halogen, -CN, -C=C-CN, or alkyl having 1 to 10 carbon atoms; A<1>, A<2>, A<3>, and A<4 >each are, for example, independently 1,4-cyclohexylene, 1,4-cyclohexenylene, 1,4-phenylene, or 1,4-phenylene; Z<1>, Z<2 >and Z<3 >each are independently a single bond, -(CH2)2-, -OCH2-, -CH2O-, -CH=CH-, -C=C-, -(CH2)4-, -O(CH2)3-, -(CH2)3O-, -COO-, -OCO-, -OCF2-, or -CF2O-; and p and q each are independently 0 or 1.
