Abstract:
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. A color filter is provided on the passivation film, and a 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 &mgr;m is provided so as to cover the black matrix. Further, a second overcoat layer with film thickness of approximate 0.5 &mgr;m 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.
