Multi-Domain Alignment of Liquid Crystal Using a Stamp of Anisotropic Morphology Fabricated by a Directional Polymerization of Reactive Mesogen

Abstract

We proposed a simple method to control liquid crystal (LC) alignments by a replication method of directional polymerization of reactive mesogen (RM). The RM polymer structures with nano-grooves were prepared by ultraviolet exposure to the RM mixed alignment layer in a LC cell and transferred to a polyimide by stamping method, which directly replicated the LC alignments of the LC cell. The transferred polyimide layer generated the stable multi-domain alignments of the LC without any aligning processes nor any electrode patterns.
