Abstract
A color filter substrate for a liquid crystal display device is obtained by patterning color filters on a transparent substrate, selective-coating an overcoat layer on the substrate, and forming a common electrode and a black matrix to be connected each other, without any further step. This color filter substrate compensates a high sheet resistance of the common electrode and reduces a crosstalk and a surface reflection rate of the panel. In addition, the black matrix is formed on the color filters, and thus the reduction of the resistance of the common electrode is available. A process for forming the ITO layer on the black matrix is only required as an additional process, so that the step coverage is improved and thus no polyimide-off phenomenon is resulted during the rubbing process, while improving poor quality pixels which may be produced by the light leak and the polyimide-off.
