A liquid crystal display device is made up of a TFT substrate, an opposed substrate and a liquid crystal layer arranged between these substrates, in which the TFT substrate is provided with gate lines, data lines and TFT on its transparent insulative substrate, in addition, a passivation film is provided so as to cover them. Color filter is provided on the passivation film, and black matrix is provided at 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 nullm is provided so as to cover the black matrix. Further, a second overcoat layer with film thickness of approximate 0.5 nullm 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.
