Abstract
A liquid crystalline composition is disclosed. The composition comprises at least one liquid-crystal compound and at least one fluoroaliphatic group-containing polymer of a formula (1-1). In the formula, i and j each indicate an integer equal to or more than 1; M represents k types of repetitive units each derived from an ethylenic unsaturated monomer (k indicates an integer equal to or more than 1); a, b and c each mean a mass percentage indicating a polymerization ratio; R11 and R12 each represent a hydrogen atom or a methyl group; X1 and X2 each represent an oxygen atom, a sulfur atom or —N(R13)—; R13 represents a hydrogen atom or an alkyl group having from 1 to 4 carbon atoms; m1 and m2 each indicate an integer of from 1 to 6; and n1 indicates an integer of from 0 to 3.
