The present invention provides a polymerizable compound represented by formula (I), in which: R1 and R2 indicate –C(=O)–X–Sp3–Q3, etc.; n1 and n2 are integers of 0 to 4; X indicates –O–, etc.; Z1 indicates an arylene group, etc., Z2 indicates a trans-1,4-cyclohexylene group, an arylene group, etc., m1 is the integer 1 or 2, m2 is an integer of 0 to 2, L1 and L2 indicate –C(=O)O–, –OC(=O)–, etc., Sp1, Sp2, and Sp3 indicate an alkylene group, a group obtained by having one or more –CH2– moieties are substituted by –O– in an alkylene group, etc., Q1 and Q2 indicate a polymerizable group, and Q3 represents a hydrogen atom or a polymerizable group. The present invention also provides a polymer obtained by polymerizing the polymerizable compound, a polymerizable composition that contains the polymerizable compound, and a film formed from the polymerizable composition. This polymerizable compound can be used as a low-birefringence liquid crystal. |
