Title: Color filter substrate having color filter portions of different thickness, and overcoating layer on common electrode, LCD having the same, and method of manufacturing

Abstract: A color filter substrate includes a substrate, a color filter and a common electrode. The substrate includes a transmissive region and a reflective region adjacent to the transmissive region. The color filter is formed on the substrate, and the color filter includes a first portion formed in the transmissive region, and a second portion formed in the reflective region. The first and second portions have different thickness each other. The common electrode is disposed on the color filter. The common electrode includes a third portion formed in the transmissive region, and a fourth portion formed in the reflective region. The third portion and the fourth portion have different height each other with respect to the substrate. Thus, a luminance becomes uniform, even though a light passes through the liquid crystal layer of the reflective region twice, and a light passes though the liquid crystal layer of the transmissive region once.
