The amphiphilic reactive monomer consisting of hydrophilic and hydrophobic moieties, and a reactive vinyl functional group was designed and synthesized for the formation of automatic vertical alignment (VA) layer of liquid crystal (LC). Some reactive monomers in LC mixture were migrated on the substrates by phase separation and other reactive monomers was dispersed in the LC mixture. For stabilization of automatic VA layer, reactive monomers were polymerized by UV light with methacryl polyhedral oligomeric silsesquioxane (MAPOSS) as a crosslinker. Polymerized reactive monomer and MAPOSS formed nanoparticles and were migrated on substrate during polymerization by phase separation induced polymerization. The polymer-stabilized automatic VA layer exhibited a strong surface anchoring energy without any light scattering.
