Abstract
Decal technology is employed to provide a color filter layer for a thin film transistor liquid crystal display device. The red/green/blue color regions and an opaque surround are printed on a suitable substrate using gravure printing techniques and colored glass frit materials. Once the printed decal is transferred to one of the glass panels, it can be heated to fuse it to the glass. Electrodes can be deposited directly on this fused color filter layer.
