Abstract
Using ion-beam (IB) irradiation, liquid crystals (LCs) were vertically aligned (VA) on a γ -Al2O3 alignment film. Atomic-layer deposition was used to orient the LCs on high-quality γ -Al2O3 alignment films. The LC molecule orientation indicates the vertical direction of the atomic-layer-deposited γ -Al 2O3 alignment films. X-ray photoelectron spectroscopy showed that IB irradiation changed the chemical structure, shifting the Al-O binding energy and altering the Al-O bonding intensity. The low-voltage transmittance characteristics of the VA LC displays on the γ -Al 2O3 alignment films were also measured, showing reduced voltage and power requirements.
