a plurality of signal structures on a substrate, wherein each signal structures includes a plurality of consecutively arranged gate lines, a plurality of consecutively arranged data lines crossing the gate lines, and a plurality of TFTs arranged at crossings of the gate and data lines;

a protective film formed over the signal structures, wherein the protective film comprises a contact hole to expose a drain electrode of TFT over the signal structures;

a plurality of pixel electrodes connected to corresponding ones of the TFTs through each contract hole at first connection areas; and

a plurality of patterned color filters on the protective film between the signal structures and the pixel electrodes, wherein adjacent ones of patterned color filters overlap each other at regions over at least one of the plurality of signal structures, each patterned color filter comprises a concave part corresponding the contact hole which a width of the contact hole is less than a width of the concave part, and a portion of the protective film and the portion of the drain electrode are exposed by the concave part and the contact hole.
