We proposed a direct atomic force microscope (AFM) nanostroking (DANS) method in which an AFM probe tip is scanned in a liquid crystal (LC) solution, and we evaluated the quantitative distribution of LC molecules using a birefringence-contrast scanning near-field optical microscope with sub-micrometer resolution. The experimental results showed that LC molecules were aligned with a weak load force of 0 nN or the attractive-force region, and they could be reoriented on a hard polyimide film by surface adsorption. Using our method, radial and octatetracontagonal LC alignment patterns were also demonstrated. These results suggest that the DANS method will be effective for fabricating complex LC alignment patterns.
