摘要：
A polymerizable liquid crystal composition includes a liquid crystal compound having a polymerizable group, wherein the composition includes 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): 2) has a fluorine group content of 3 to 30% by weight, 3) has a ratio of side chains containing the group represented by the general formula (h) relative to the 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.
