Recently, as the demand for a non-contact liquid crystal alignment method capable of improving viewing angle characteristics has spread throughout the industry, various non-contact liquid crystal alignment methods, including conventional UV light alignment, are being actively studied. In the case of UV light alignment, it is currently applied to mass production in many fields and shows relatively excellent initial characteristics, but there is a problem of display quality deterioration over time. In this study, among these non-contact liquid crystal alignment methods, the liquid crystal is oriented by quantitatively irradiating an ion beam onto the SiOF inorganic film, which has excellent initial characteristics and does not cause deterioration in quality over time., the electro-optical properties were evaluated by manufacturing a commercial-level IPS (In-Plane Switching) liquid crystal cell. In particular, in the case of such inorganic film orientation, it is common to have many problems with orientation stability, but the evaluation cell manufactured by the method proposed in this study is capable of maintaining a uniform orientation without losing orientation even after heat treatment at a high temperature of 200°C. could be observed.
