  • Patent number: 7868960
    Abstract: An active matrix substrate includes a plurality of transistors. A source electrode is connected with a data signal line, and a drain electrode is connected with a pixel electrode in each transistor. The source electrode is located on a semiconductor layer, and at least a portion of the drain electrode is overlapped with the gate electrode. A gate insulating film covering the gate electrode of each transistor has a thin section having a reduced film thickness, at a portion where the gate insulating film is overlapped with each gate electrode. An overlapping area of the thin section with the source electrode is smaller than an overlapping area of the thin section with the drain electrode. Thus, the active matrix substrate can prevent the generation of short-circuits between the signal lines (between the data signal line and a scanning signal line) in a TFT forming region, while guaranteeing TFT characteristics.

  • Publication number: 20100181489
    Abstract: Intended is to suppress the separation by a thermal stress between an upper substrate and a lower substrate jointed through a joint member, and to suppress a creeping discharge from an upper electrode to a lower electrode. An active matrix substrate and a glass substrate are jointed at their outer peripheral portions so that the joint area, in which the active matrix substrate and the glass substrate are jointed, can be reduced. This makes it possible to reduce the thermal stress to be caused between the active matrix substrate and the glass substrate, and to suppress the separation between the active matrix substrate and the glass substrate jointed with an adhesive resin.
