We studied the effects of liquid crystal (LC) alignment characteristics on a SiOx thin films of various thicknesses deposited at an oblique angle of 45° by RF magnetic sputtering. A uniform LC alignment characteristic was achieved on the SiOx thin film, and the pretilt angle was about 90°. The thermal stability of the SiOx thin film was sustained until 200°C. There was no difference in LC aligning capability owing to the thickness of SiOx thin film obliquely deposited at 45°. The vertical alignment liquid crystal display (VA-LCD) on the SiO x thin film deposited at the oblique angle of 45° by sputtering showed good electrooptical characteristics. These results suggest that a uniform homeotropic LC alignment can be achieved and a large VA-LCD can be produced by sputtering.
