The invention provides a compound having two polymerizable groups, wherein one is bonded directly to the ring and the other is bonded to the ring through a spacer, as a compound in which the polymerizability is not decreased and the solubility is high in a liquid crystal composition. A compound represented by formula (1), wherein
in formula (1), for example, A
1
and A
2
are 1,4-phenylene in which at least one hydrogen has been replaced by fluorine; Z
1
is alkylene having 1 to 12 carbons; Z
2
is alkylene having 1 to 12 carbons; X
1
is hydrogen, fluorine, methyl or trifluoromethyl; P
1
is a polymerizable group; and a is an integer from 0 to 3.
