Abstract:
An active matrix liquid crystal display device comprising:a pixel matrix composed of pixels that have pixel transistors, liquid crystal capacitance and storage capacitance, wherein said liquid crystal capacitance and said storage capacitance are connected to data lines through the pixel transistors, wherein each pixel is disposed at respective intersections between the data lines and gate lines arranged longitudinally and latitudinally, respectively; a data driver circuit for driving the data lines; and gate driver circuits for driving the gate lines, wherein said pixel matrix, said data driver circuit and said gate driver circuits are all manufactured on the same substrate, said data driver circuit and said gate driver circuits are formed outside a sealing region located outside said pixel matrix, and all the data lines formed between said data driver circuit and said pixel matrix are substantially covered by at least one metal layer which is composed of a different metal from that of the data lines; wherein said metal layer is adapted to perform both light shielding and reduction of electrostatic coupling capacitance between said data lines.
