| Outline of Final Research Achievements |
A protocol to observe defects in the alignment of liquid crystals in real space and with high resolution was proposed. Two types of photopolymerizable monomers were employed to prepare a film with the liquid crystal alignment preserved, and observations were made using a transmission electron microscope (TEM). Although the employed materials did not give rise to a satisfactory contrast in the TEM, the proposed protocol enabled the fabrication of films with well-preserved liquid crystal alignment. Improvement of materials should therefore enable real-space observation of liquid crystal defects with a resolution well beyond that possible with the current optical observation methods.
