Abstract

We present the characteristics of titanium dioxide (TiO₂) inorganic film deposited by RF magnetron sputtering for liquid crystal display applications in this paper. TiO₂ films supported vertically aligned liquid crystal (LC) molecules based on ion-beam (IB) irradiation time dependence. Uniform alignment was obtained only when the incident time was two minutes with 1.8 keV of incident energy and an incident angle of 45°. Energy from uniform high-density plasma by IB irradiation affected the interaction between the TiO₂ layer and LC molecules to produce vertical alignment of the LC molecules.
