A compound represented by formula (i) has, as Ki1 in the formula (i), a structure represented by any one of formula (K-1) to formula (K-3). When used in a liquid crystal composition, it adheres to substrates which hold the liquid crystal composition (liquid crystal layer) therebetween, thereby permitting liquid crystal molecules to be maintained in the state of being aligned in the vertical direction. The liquid crystal composition using the compound enables liquid crystal molecules to be aligned even when the PI layer is not provided (vertical alignment of liquid crystal molecules is induced without the voltage applied and horizontal alignment of liquid crystal molecules is realized with the voltage applied). It is possible to provide a polymerizable compound being excellent in storability and capable of uniform vertical alignment of liquid crystal molecules with no PI layer provided.
由式(i)表示的化合物,作为式(i)中的 Ki1,具有由式(K-1)至式(K-3)中任一项表示的结构。在液晶组合物中使用时,它能粘附在夹持液晶组合物(液晶层)的基底上,从而使液晶分子保持垂直方向排列的状态。使用该化合物的液晶组合物即使在不提供 PI 层的情况下也能使液晶分子排列整齐(在不施加电压的情况下诱导液晶分子垂直排列,在施加电压的情况下实现液晶分子水平排列)。这种可聚合化合物具有极佳的贮存性,在不提供 PI 层的情况下也能实现液晶分子的均匀垂直排列。
