Abstract

Inorganic alignment layer (IAL) was deposited on an indium-tin-oxide (ITO) by using reactive sputtering deposition method. After deposited, IAL was irradicated by Ar+ ion beam (IB) for liquid crystal (LC) alignment. IAL treated by various conditions such as IB energy, IB incident angle, and IB Irradiation time had excellent alignment property and electro-optical property the same as that of PI. We Investigated into the stability of ion beam treated IAL after a lapse of long time. However IAL irradiated IB did not occur degradation of electro-optical property. The results implied that IAL Irradiated IB was adopted as LC alignment layer Instead of rubbed polyimide.
