摘要： There is disclosed a manufacturing method of highly integrated circuits with thin-film transistors (TFTs) for use as peripheral driver circuitry in active-matrix liquid crystal display (LCD) panel with a pixel array each having a charge transfer control TFT, capable of facilitating formation of contact holes otherwise being difficult in cases where an anode oxide film is formed on gate electrodes of TFTs and lead wires both of which are made of anodizable metal, such as aluminum. The method includes execution of anodization while causing a resist mask to be disposed on part of the lead wire and electrode made of aluminum, thereby partly eliminating formation of the anode oxide film on the lead wire and electrode. At a later step of fabrication, each contact is formed by use of such portion that has no anode oxide film formed thereon. This may allow aluminum to be employed as lead wires while enabling easy fabrication of contacts therefor.

摘要： An active matrix liquid crystal display having a high aperture ratio is provided. Retaining capacitors are created between a black matrix and pixel electrodes via a dielectric layer made from an organic resinous material or inorganic material. Those regions of the black matrix which cover TFTs are fully utilized. Therefore, wider area can be used to display an image than heretofore. In the present invention, the difference in relative dielectric constant between different dielectric layers is employed. Therefore, retaining capacitors can be created without the need to take account of parasitic capacitance.

摘要： Method of forming an active layer for TFTs without plasma-damaging the side surfaces of the active layer. The method is started with forming a crystalline silicon film on a glass substrate. A resist mask is placed on the silicon film. The silicon film is etched with an etchant gas consisting mainly of a halogen fluoride gas, thus forming the active layer. During this process, the etchant gas is not changed into a plasma to prevent the side surfaces of the active layer from being plasma-damaged. ClF3 can be used as the halogen fluoride gas.

摘要： In forming four liquid crystal panels on a glass substrate, layout is so made that peripheral driving circuit areas of the respective panels are opposed to each other. With this layout, the peripheral driving circuit areas, which are prone to be affected by particles, are prevented from existing in regions close to the perimeter of the glass substrate. This allows liquid crystal panels to be produced at a high yield, as well as enables efficient use of the glass substrate.

摘要： An active matrix display device comprising an integrated peripheral driver circuit improved in image quality, provided in such a constitution that the feed through voltage &Dgr;Vs is set lower than the voltage Vgr necessary for realizing a single gradation. In this manner, a stable gradation display is obtained without being influenced by the feed through voltage &Dgr;Vs even when the fluctuation in the characteristics of the thin-film transistors provided in active matrix circuit may fluctuate the &Dgr;Vs.

摘要： In an active matrix display device integrated with a peripheral drive circuit using thin film transistors, when Vgr is a voltage required for one gradation, Ct is capacitance of all pixels, Cgd is capacitance between a gate and a drain, .DELTA.Vg is a difference between ON/OFF gate voltages, and .DELTA.Vs is a feedthrough voltage, the respective parameters satisfy an expression: .vertline.Vgr.vertline.>.vertline.(1/Ct) [Cgd.multidot..DELTA.Vg-Ct.multidot..DELTA.Vs].vertline.. According to this, even if dispersion occurs in the characteristics of the thin film transistors arranged for a buffer circuit or an active matrix circuit, it is possible to prevent the dispersion from influencing the gradation display.
