An object is to provide a polymerizable compound having high polymerization reactivity, a high conversion ratio and high solubility in a liquid crystal composition, a polymerizable composition containing the compound, a liquid crystal composite prepared from the composition, and a liquid crystal display device having the composite. A solution is a polymerizable compound represented by formula (1).;;In the formula, for example, P1 and P2 are —OCO—(CH3)C═CH2; S1 and S2 are a single bond; ring A1, ring A2 and ring A3 are 1,4-phenylene; Z1, Z2 and Z3 are a single bond; two of G is —CH═ or —N═; and a is 0 or 1. |

1. A compound represented by formula (1):wherein, in formula (1),
P1 and P2 are independently a polymerizable group; S1 and S2 are independently a single bond or alkylene having 1 to 6 carbons, and in the alkylene, at least one of —CH2— may be replaced by —O—, —COO—, —OCO—, —CH═CH— or —C≡C—; ring A1, ring A2 and ring A3 are independently cyclohexylene, cyclohexenylene, phenylene, naphthylene, anthracenylene, tetrahydropyranylene, dioxanylene, pyrimidinylene or pyridinylene, and in the groups, at least one of hydrogen may be replaced by halogen, alkyl having 1 to 12 carbons, alkoxy having 1 to 12 carbons, alkyl having 1 to 12 carbons in which at least one of hydrogen is replaced by halogen, or alkoxy having 1 to 12 carbons in which at least one of hydrogen is replaced by halogen, one or two of hydrogen may be replaced by —S3—P3, P3 is defined herein in a manner identical with the definition of P1 or P2, and S3 is defined in a manner identical with the definition of S1 or S2; two of G are —CH═ or —N═; Z1, Z2 and Z3 are independently a single bond, —COO—, —OCO—, —CH═CH—, —CH═CH—COO—, —OOC—CH═CH—, —C(CH3)═CH—COO—, —OOC—CH═C(CH3)—, —CH═C(CH3)—COO—, —OOC—C(CH3)═CH—, —C(CH3)═C(CH3)—COO—, —OOC—C(CH3)═C(CH3)—, —C≡C—, —COCH═CH—, —CH═CHCO—, —C(CH3)═C(CH3)—, —CH═CH—CH2O—, —OCH2—CH═CH—, —CH═CH—OCH2—, —CH2O—CH═CH— or —CO—; and a is 0 or 1. |
