Abstract
A liquid crystal composition comprises liquid crystal molecules and an alignment promoter. The alignment promoter is represented by the formula (I).(Hb—)mL(—Bu)n  (I)In the formula (I), 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. Each of m and n is independently an integer of 1 to 12.
