    摘要: An object of the invention is to increase the rate of conforming articles by reducing defects due to leakage of supplementary capacitances in an active-matrix liquid crystal display apparatus of a Cs on Com structure having supplementary capacitances. In a normally-white mode active-matrix liquid crystal display apparatus, a plurality of gate signal lines and source signal lines are formed so as to intersect at right angles, pixel capacitors are connected to the intersections through TFTs, and image display is performed. To the pixel capacitors, supplementary capacitances are connected in parallel. Supplementary capacitance lines are driven by a supplementary capacitance drive circuit so that a potential difference not less than a threshold value of the liquid crystal is maintained from common signal lines on a counter electrode substrate. When a leakage occurs at a supplementary capacitance, the potential difference not less than the threshold value of the liquid crystal is maintained at both ends of the pixel capacitor, so that the pixel is prevented from becoming a bright point and the active-matrix liquid crystal display apparatus is prevented from being defective. Consequently, the rate of conforming articles can be increased.

    摘要: An active matrix substrate includes base substrate, gate lines, data lines, thin-film transistors and pixel electrodes. The gate lines are formed on the base substrate. The data lines are formed over the gate lines. Each of the data lines crosses all of the gate lines with an insulating film interposed therebetween. The thin-film transistors are formed over the base substrate. Each of the thin-film transistors is associated with one of the gate lines and operates responsive to a signal on the associated gate line. Each of the pixel electrodes is associated with one of the data lines and one of the thin-film transistors and is electrically connectable to the associated data line by way of the associated thin-film transistor. Each of the pixel electrodes and the associated thin-film transistor are connected together by way of a conductive member. Each of the pixel electrodes crosses one of the gate lines, while the conductive member for the pixel electrode crosses another one of the gate lines that is adjacent to the former gate line.

    摘要: A thin-film transistor of the reversed stagger type is provided with a gate electrode, first and second gate insulating films, a semiconductor layer, separated contact layers, and source electrodes and drain electrodes, all of which are stacked on a substrate. Upon manufacturing the thin-film transistor of this type, a gap section is pattered in a single contact-material layer. In this case, the contact-material layer is patterned by carrying out etching by the use of the source electrode and drain electrode as direct masks or by the use of a resist pattern that was used for forming the respective electrodes. Upon patterning a gap section in the contact-material layer between the source electrode and the drain electrode, no dedicated resist pattern is required; therefore, it is possible to reduce the number of the processes as compared with conventional manufacturing methods. Consequently, it becomes possible to reduce the production cost of thin-film transistors and also to improve the yield of desired products.
