Abstract

Alignment of liquid crystals by ion-beam (IB) irradiated bismuth-doped zinc oxide (BZO) films was investigated. The BZO alignment layer was deposited using a simple solution process, and IB irradiation of the BZO was used to induce surface-alignment of LC molecules uniformly. Solution-processed thin films have numerous advantages, including low manufacturing cost, simplicity of fabrication, and high productivity. IB irradiation of the BZO film induces a drastic improvement in the uniformity of the BZO surface and creates physico-chemical modifications that preserve the anisotropic characteristics of the surface, thereby unidirectionally aligning the LC molecules.
