We introduce the characteristics of the titanium dioxide $\left(\mathrm{Ti}{\mathrm{O}}_2\right)$ inorganic film deposited by rf magnetron sputtering for liquid crystal display applications. The $\mathrm{Ti}{\mathrm{O}}_2$ films demonstrated vertical alignment (VA) of the liquid crystals (LCs) obtained by using ion-beam (IB) bombardment. As observed by using x-ray photoelectron spectroscopy, the chemical structure of the $\mathrm{Ti}{\mathrm{O}}_2$ was changed by IB bombardment, altering the Ti–O bonding of the Ti $2p$ spectra to lower intensity levels. Breaking Ti–O bonding by IB bombardment created pretilt angles between the $\mathrm{Ti}{\mathrm{O}}_2$ film and LC molecules. The better voltage-transmittance characteristics of the VA LCDs based on $\mathrm{Ti}{\mathrm{O}}_2$ film were measured and compared with the same characteristics of polyimide film.
