The present invention provides a polymerizable composition containing a polymerizable liquid crystal compound represented by Formula (I) and an oxime compound, in the formula, A1 and A2 each represent a phenylene group or a trans-1,4-cyclohexylene group, L1 and L2 each represent single bond, —C(═O)O—, or —OC(═O)—, Q1 and Q2 each represent a polymerizable group or the like, m and n represent an integer of 0 to 2, X may represent —X3-Sp3-Q3 or two X's may be bonded to each other to form a fused ring, X3 represents —C(═O)O—, Sp1, Sp2, and Sp3 each represent single bond, an alkylene group, or the like, Q3 represents hydrogen atom, a cycloalkyl group, a polymerizable group, or the like, and l represents an integer of 0 to 4. The polymerizable composition hardly causes yellowing after curing and is useful for manufacturing a film and a half mirror for displaying a projection image.
