To provide a spontaneous alignment aid for a liquid crystal composition that can ensure storage stability when added to a liquid crystal composition and enables vertical alignment of liquid crystal molecules without providing a PI layer. The spontaneous alignment aid for a liquid crystal composition of the present embodiment has a partial structure represented by the formula (i), in particular, the formula (K-1) to the formula (K-11) as K i1 in the formula (i). Since it contains a compound having a structure represented by any of the above, when it is used in a liquid crystal composition, it is adsorbed on a substrate sandwiching the liquid crystal composition (liquid crystal layer), and aligns liquid crystal molecules in the vertical direction. It can be held in the state. Therefore, according to the spontaneous alignment aid for a liquid crystal composition of the present embodiment, liquid crystal molecules are aligned without providing a PI layer (inducing vertical alignment of liquid crystal molecules when no voltage is applied and horizontal alignment of liquid crystal molecules when voltage is applied).
