When added to a liquid crystal composition, storage stability can be ensured, and even if the PI layer is omitted, an alignment aid that voluntarily vertically aligns the liquid crystal molecules is provided. Further, a liquid crystal composition having excellent storage stability and allowing vertical alignment of liquid crystal molecules, and a liquid crystal display device using the liquid crystal composition, is provided even when the PI layer is omitted. The alignment aid of the present invention is disposed together with liquid crystal molecules between two substrates, and the liquid crystal molecules are spontaneously aligned. The alignment aid includes at least one first compound having at least one first affinity group having an affinity for the substrate, and at least one compound having an affinity for the substrate and having a lower polarity than the first affinity group. It is characterized by containing a second compound containing a second affinity group. |
