The present invention provides a spontaneous alignment aid for a liquid crystal composition, which can ensure storage properties when added to a liquid crystal composition, and can form a vertical alignment of liquid crystal molecules even if a PI layer is not provided.n n n The spontaneous alignment aid for the liquid crystal composition of the present embodiment contains a compound having a partial structure represented by formula (i), especially one represented by any one of formula (K-1) to formula (K-11) The structure is the compound of K i1 in formula (i). When used in a liquid crystal composition, it will be adsorbed on the substrate holding the liquid crystal composition (liquid crystal layer), and the liquid crystal molecules can be kept aligned in a vertical direction. Therefore, according to the spontaneous alignment aid for liquid crystal composition of this embodiment, even if no PI layer is provided, the liquid crystal molecules can be aligned (when no voltage is applied, the vertical alignment of the liquid crystal molecules is induced, and when a voltage is applied, the liquid crystal molecules are realized The horizontal alignment). |
