A color filter substrate includes a transparent substrate, a first and second reflective layers, a spacer layer, and an interference layer. The spacer layer is interposed between the two reflective layers and includes a plurality of first, second and third regions that are distinguished from one another according to their respective thicknesses, where the first, second and third regions overlap red, green and blue pixel portions, respectively. An interference layer is formed on the second reflective layer at positions overlapping the red pixel portions.
