A compound represented by formula (1):
wherein R1 is hydrogen or alkyl having 1 to 20 carbons, in which in the alkyl, arbitrary —CH2— may be replaced by —O—, —S—, —COO—, —CH═CH— or —C≡C—, and arbitrary hydrogen may be replaced by halogen or alkyl having 1 to 3 carbons; ring A1, ring A2, ring A3, ring A4 and ring A5 are each independently a benzene ring, a piperidine ring, a tetrahydropyrane ring or a dioxane ring, in which in the rings, arbitrary hydrogen may be replaced by halogen, alkyl having 1 to 3 carbons, alkoxy having 1 to 3 carbons or halogenated alkyl having 1 to 3 carbons, and —CH═ may be replaced by —N═; Z1, Z2, Z4, Z5 and Z6 are each independently a single bond, —COO— or —CF2O—; Z3 is a single bond or —CF2O—, and in the case where Z3 is a single bond, ring A3 is a ring represented by formula (RG-5), or L1 and L2 are both fluorine, or at least one of Z1, Z2, Z4, Z5 and Z6 is —CF2O—; L1, L2, L3 and L4 are each independently hydrogen or halogen; X1 is hydrogen, halogen, —C≡N, —N═C═S, —C≡C—C≡N, —SF5 or alkyl having 1 to 10 carbons, in which in the alkyl, arbitrary —CH2— may be replaced by —O—, —S—, —CH═CH— or —C≡C—, and arbitrary hydrogen may be replaced by halogen; and l, m, n, o and p are each independently 0 or 1, provided that l+m+n+o+p≦4:
