The present disclosure provides a method for fabricating a color filter substrate. The method comprises: forming an indium tin oxides (ITO) layer on a surface of the glass substrate and depositing a silver nanoparticle layer on a surface of the ITO layer by electrophoretic deposition to obtain a conductive layer. The present disclosure further provides a color filter substrate fabricated by the above method and a liquid crystal display panel comprising the same. The deposition of silver nanoparticles on the surface of the ITO layer by electrophoretic deposition reduces an impedance of the ITO layer, thereby reducing resistor-capacitor delay and making a liquid crystal alignment more complete.
