Abstract:
An active-matrix type liquid crystal display device comprising:first and second transparent substrates being arranged opposite to each other; a plurality of gate lines and data lines formed on a surface of said first transparent substrate being in opposite state to said second transparent substrate, in which the gate lines and the data lines cross mutually; a thin film transistor, provided at the surface of said first transparent substrate, in which said gate line is connected to its gate electrode and said data line is connected to one of a source/drain electrode of said thin film transistor; a color filter at least at a pixel area, said pixel area is an area surrounded by said gate line and said data line except for a transistor formation area on which said thin film transistor is formed and a data line formation area on which said data line is formed; an overcoat layer which is provided in such a way as to cover at least an end section of both said thin film transistor and said color filter, said overcoat layer comprising: a thin film part which is formed, at least, on said pixel area, and a thick film part which is formed on at least said transistor formation area, a film thickness of the thick film part is thicker than a film thickness of said thin film part; a pixel electrode which is provided at said pixel area, the pixel electrode is connected to the other of said source/drain electrode; an opposed electrode which is provided at a surface of said second transparent substrate being in opposite state to said first transparent substrate; and liquid crystal which is provided between said first transparent substrate and said second transparent substrate, wherein said thick film part is formed in such a way as to pile up a plurality of layers, wherein said overcoat layer is formed from a first overcoat layer and a second overcoat layer, in which said thin film part consists of only said second overcoat layer and said thick film part is formed in such a way as to pile said first overcoat layer up said second overcoat layer.
