The molecular orientation properties and the detailed polarization distribution of ferroelectric liquid crystals are complicated and there are many unresolved factors. In this study, we investigated the polarization state of ferroelectric nematic liquid crystals at the interface by focusing on the interfacial parameters of pretilt and polarity of the alignment film. We found that the polarization direction at the interface can be uniquely determined by applying a pretilt treatment, and that the domain can be controlled in the vertical direction by controlling the polarity of the alignment film.
