Abstract Novel process architectures are proposed for fabricating large area, high resolution TFT‐LCD's with a minimal number of process steps. A low contact resistance between Al bus lines and transparent conductive oxide layer, necessary for large‐area panels, is obtained by inducing a self‐formed, inter‐metallic compound layer at the interface without using any additional buffer or capping layers. For enhanced brightness and resolution, a new TFT array structure integrated on a color filter substrate, named Array on Color Filter (AOC) structure, has been developed. Good quality TFT's are successfully constructed on the newly developed color filter for AOC within a sufficiently wide process margin. By adopting these novel technologies, a 17.0″ SXGA prototype panel is fabricated and shows good display performance.
