PURPOSE: An active-matrix type liquid crystal display device and the manufacturing method are provided to obtain a CF(Color Filter) on TFT(Thin Film Transistor) structure to surely protect color filter or black matrix while not reducing transmittance. CONSTITUTION: A liquid crystal display device is made up of a TFT substrate, an opposed substrate and a liquid crystal layer(3) arranged between the substrates. The TFT substrate is provided with gate lines(5), data lines(7) and TFT(17) on the transparent substrate, in addition, a passivation film is provided to cover the gate lines, the data lines, and the TFT. Color filter is provided on the passivation film, and black matrix is provided at the corresponding area to above part of the TFT and to above part of the data line on the color filter. In addition, a first overcoat layer with film thickness of degree of 1 to 3 μm is provided so as to cover the black matrix. Further, a second overcoat layer with film thickness of approximate 0.5 μm is provided at the whole surface except for a contact hole. Furthermore, a pixel electrode is provided on pixel formation area on the second overcoat layer.
