The present invention relates to a composition comprising a polymerizable compound and a rodlike polymerizable liquid crystal compound represented by formula (1). P2-E2-X2-B2-A2-(G2)t-Y-(G1)s-A1-B1-X1-E1-P1 (1) (wherein, Y is a divalent group; s and t are independently an integer of 0 or 1; when s and t are 1, G1 and G2 are independently -CR1R2-, R1 and R2 are independently an alkyl group having 1 to 4 carbon atoms, a halogen atom, and a hydrogen atom; A1 and A2 are independently a divalent cyclic hydrocarbyl group, a divalent heterocyclyl group, a methylene phenylene group, an oxyphenylene group, a thiophenylene group; B1 and B2 are divalent groups; X1 and X2 are divalent groups; E1 and E2 are independently an alkylene group having 2 to 25 carbon atoms; P1 and P2 are hydrogen atoms or polymerizable groups, and at least one of P1 and P2 is a polymerizable group). |
