摘要:
A substrate for wiring an electrical component in an electrical circuit comprises a base substrate, a first insulating layer of an organic material formed over the base substrate, a wiring member formed on the first insulating layer, coupled to the component, a second insulating layer of an organic material formed over the first insulating layer, and a terminal member on the first insulating layer and appearing from the second insulating layer, connected to the wiring member. A third insulating layer of an organic material may be interposed between the first and the second insulating layers, carrying a second wiring member connected to the first wiring member.

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:
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 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:
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.
