Provided is a polymerizable liquid crystal composition that is suitable for optical films which exhibit excellent heat resistance, and wherein a shift in the selective wavelength due to a thermal history is small. A polymerizable liquid crystal composition which contains a bifunctional polymerizable liquid crystal compound represented by general formula (I-2), a chiral compound and an oxime ester-based polymerization initiator. (In general formula (I-2), each of P 121 and P 122 represents a polymerizable functional group; each of Sp 121 and Sp 122 represents a C1-18 alkylene group, a single bond or the like; each of X 121 and X 122 represents -O-, -S- or the like; each of q121 and q122 represents 0 or 1; and MG 122 represents a mesogenic group represented by general formula (I-2-b). In general formula (I-2-b), each of A1, A2 and A3 represents a 1, 4-phenylene group, a 1, 4-cyclohexylene group or the like; each of Z1 and Z2 represents -COO-, -OCO- or the like; and r1 represents 0, 1, 2 or 3.) |
