The conventional composition (ceramic solution), which is obtained by dissolving, in a solvent, a polymerizable liquid crystal compound used in preparation of an optical film included in a polarizing plate and a retarder plate, has a problem of generation precipitates of the polymerizable liquid crystal compound in the ceramic solution. Provided is a composition including a polymerizable liquid crystal compound represented by formulae (2-1) and (2-2) and a solvent. In chemical formulae, m and n are integers of 1 or more; B is -CO-O-; E is -CO-O-; G is a divalent alicyclic hydrocarbon group having 3-16 carbon atoms; A is a divalent alicyclic hydrocarbon group having 3-16 carbon atoms, or a divalent aromatic hydrocarbon group having 6-20 carbon atoms; F is an alkanediyl group having 1-12 carbon atoms; P is a hydrogen atom or a polymerizable group; W is a divalent aliphatic hydrocarbon group having 1-13 carbon atoms, a divalent alicyclic hydrocarbon group having 3-13 carbon atoms, a divalent aromatic hydrocarbon group having 6-20 carbon atoms; and X is a divalent aromatic hydrocarbon group having 6-20 carbon atoms, or a divalent aromatic heterocyclic group having 3-20 carbon atoms. |
