ABSTRACT:
A layer of discotic liquid crystal having a molecular structure including a disk-shaped core and plural side chains connected to the core is disposed in contact with a substrate boundary provided with a homeotropic alignment power for aligning the side chains of the discotic liquid crystal molecules vertically to the boundary, whereby a uniform columnar structure vertical to the substrate of the discotic liquid crystal is formed. As a result, a discotic liquid crystal device having a stable homeotropic monodomain alignment can be formed from a wide scope of discotic liquid crystal materials.
