Abstract:
A liquid crystal composition comprising liquid crystal molecules and an alignment promoter represented by the formula (I) in an amount of 0.01 to 20 wt. % based on the amount of the liquid crystal molecules:(Hbâ€”)mL(â€”Bu)nâ€ƒâ€ƒ(I) in which Hb is a hydrophobic group selected from the group consisting of a fluorine-substituted alkyl group having 1 to 40 carbon atoms, a fluorine-substituted aryl group having 6 to 40 carbon atoms, an alkyl group having 6 to 60 carbon atoms and an alkyl-substituted oligosiloxanoxy group having 1 to 60 carbon atoms; Bu is a bulky group showing an excluded volume effect and comprising at least two rings; L is an (m+n)-valent linking group; and each of m and n is independently an integer of 1 to 12.
