A compound represented by formula (i) has, as K
i1
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.
化合物的
化学式为(i),其中Ki1在
化学式(i)中表示由
化学式(K-1)到
化学式(K-3)中的任一结构。当该化合物用于液晶组合物时,它会附着在保持液晶组合物(液晶层)之间的基底上,从而使液晶分子保持在垂直方向上排列的状态。使用该化合物的液晶组合物使液晶分子可以在没有
PI层的情况下排列(液晶分子的垂直排列是在不施加电压的情况下诱导的,而施加电压后实现了液晶分子的
水平排列)。可以提供一种具有良好存储性并且能够在没有提供
PI层的情况下使液晶分子垂直排列均匀的可聚合化合物。
