Abstract
A substrate for an LCD panel includes an insulation substrate, a light-blocking layer, a color filter layer, a common electrode layer and a static electricity discharging layer. The light-blocking layer is formed on the insulation substrate to define a pixel region. The color filter layer is formed in the pixel region. The common electrode layer is formed on the color filter layer to provide the liquid crystal layer with a common voltage. The static electricity discharging layer discharges static electricity that is induced by an external stimulus to be captured within the substrate. Thus, when the static electricity induced by the external stimulus flows into the LCD panel, the static electricity may be discharged through the static electricity discharging layer, thereby preventing a spot due to the static electricity.
