Liquid crystal cells with three-dimensional orientation effect induced by aligned polymer-wall

Abstract

The three-dimensional alignment technique for liquid crystal devices is presented that consists of polymer walls made from UV-curable monomers that are oriented by an electric field while cured with a spatially patterned UV light source. From the observations of polymer wall by using polarizing Raman scattering microscopy, it was found that the polymer alignment depended on rubbing direction on two-substrates and applied electric field in photo-polymerization. This technique provides defined boundary conditions of the liquid director field in three dimensions.
