Abstract
Provided is a color filter substrate that comprises a substrate. A black matrix, a color filter layer, and a transparent conductive layer are formed on the substrate and the color filter layer is formed in a pixel area defined by the black matrix. A metal conductivity-enhanced layer is formed above and/or below the transparent conductive layer and contacts with the transparent conductive layer in an area corresponding to the black matrix.
