Abstract

In this paper, we intend to make FFS (Fringe-Field Switching) mode cell with LC alignment by using non-rubbing method, ion beam(IB) alignment method on the new a-C:H thin film, to analyze electro-optical characteristics in this cell. We studied on the suitable inorganic thin film for FFS-LCD and the aligning capabilities of nematic liquid crystal (NLC) by using the new alignment material of the a-C:H thin film as working gas at rf bias condition. A high pretilt angle of about 5° by IB exposure on the new a-C:H thin film was measured. An excellent voltage-transmittance (V-T) and response time curve of the IB-aligned FFS-LCD were observed with oblique ion beam exposure on the new a-C:H thin films.
