Effect of UV Absorption in Cell Fabrication of Polymer Stabilized Hybrid–Aligned Liquid Crystal Cell

Abstract

We have proposed a hybrid alignment nematic liquid crystal cell using a polymer stabilized technology. In a polymerization process, a UV penetration depth is carefully considered, which results in a change of polymer morphology. The UV irradiation from a homogeneous alignment substrate side causes a polymer rich layer near the substrate and the stronger scattering in the on-state.
