The spontaneous orientation aid for a liquid crystal composition provides storage stability and allows liquid crystal molecules to be vertically aligned without a PI layer when added to a liquid crystal composition. The spontaneous orientation aid for a liquid crystal composition includes a compound having a partial structure represented by formula (i), particularly in which Ki1 is represented by one of formula (K-1) to formula (K-11). When used in a liquid crystal composition, the spontaneous orientation aid can adsorb to substrates sandwiching a liquid crystal composition (liquid crystal layer) and keep the liquid crystal molecules aligned in a vertical direction. The spontaneous orientation aid makes it possible to align liquid crystal molecules without a PI layer (to induce vertical alignment of liquid crystal molecules under no applied voltage and to achieve horizontal alignment of the liquid crystal molecules under an applied voltage).
液晶组合物的自发定向助剂可提供储存稳定性,并在加入液晶组合物时允许液晶分子垂直排列而无需
PI 层。液晶组合物的自发定向助剂包括具有式(i)表示的部分结构的化合物,特别是其中 Ki1 由式(K-1)至式(K-11)中的一种表示。在液晶组合物中使用时,自发定向助剂可吸附在夹有液晶组合物的基底(液晶层)上,并使液晶分子保持垂直方向排列。自发定向助剂使液晶分子在没有
PI 层的情况下对齐成为可能(在不施加电压的情况下诱导液晶分子垂直对齐,在施加电压的情况下实现液晶分子
水平对齐)。
