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are 1,4-phenylene in which at least one hydrogen has been replaced by fluorine; Z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.
该发明提供了一种化合物,具有两个可聚合基团,其中一个直接连接到环上,另一个通过间隔连接到环上,作为一种在液晶组合物中聚合性不降低且溶解度高的化合物。一种由式(1)表示的化合物,在式(1)中,例如,A1和A2是1,4-苯基,其中至少一个氢原子被氟取代;Z1是具有1至12个碳的烷基;Z2是具有1至12个碳的烷基;X1是氢、氟、甲基或三氟甲基;P1是可聚合基团;a是从0到3的整数。
