Claim:
A polymerizable liquid crystal composition, comprising a liquid crystal compound having a polymerizable group, wherein said composition comprises from 0.1 to 6.0% by weight of a (meth)acrylic copolymer (H), which 1) has a side chain containing a fluorine group, and a side chain containing a group represented by a general formula (h): (wherein, 6-membered rings A, B, and C each represent, independently: (and said 6-membered rings A, B, and C may include a fluorine atom or a methyl group), n represents an integer of either 0 or 1, Y 1 , and Y 2 each represent, independently, a single bond, —CH 2 CH 2 —, —CH 2 O—, —OCH 2 —, —COO—, —OCO—, —C≡C—, —CH═CH—, —CF═CF—, —(CH 2 ) 4 —, —CH 2 CH 2 CH 2 O—, —OCH 2 CH 2 CH 2 —, —CH 2 ═CHCH 2 CH 2 —, or —CH 2 CH 2 CH═CH—, and Y 3 represents a hydrogen atom, a halogen atom, a cyano group, or an alkyl group, alkoxy group, alkenyl group or alkenyloxy group of 1 to 20 carbon atoms), 2) has a fluorine group content of 3 to 30% by weight, 3) has a ratio of side chains containing said group represented by said general formula (h) relative to a combined total of all side chains that falls within a range from 9 to 95 mol %, and 4) has a weight average molecular weight within a range from 10,000 to 300,000.
