Ferroelectric nematic liquid crystals are unprecedented materials that combine ferroelectricity, liquid crystallinity, and high symmetry. There are many unexplored elements in the molecular orientation properties of ferroelectric nematic liquid crystals. In this study, we focused on pretilt, which is molecular tilting at the interface, and the polarity of the alignment film as factors affecting the polarization state. From experimental results, we found that the presence of a pretilt, which breaks the out-of-plane symmetry at the interface, causes a remarkable difference between the two stable states at the interface, and only one of them is obtained. We also found that the polarity of the alignment film can change the stable state actually obtained to the other stable state.
