A matrix-type display capable of being repaired by pixel unit, Two or more of signal lines such as scanning lines, image signal lines and auxiliary signal lines and a pixel electrode are overlapped via an insulating layer, so that a defect such as the disconnection of the image signal lines and scanning lines, the short of the pixel electrode and the signal line, and the loss of electrode of a switching element, and a pixel defect can be repaired. Here, the layout of the auxiliary gate line and dual gate line can be modified.

An active matrix cell includes a first conductor group (102) formed on a transparent substrate (100), two-layered regions (103A, 103B) consisting of a semiconductor film (103a) and a first insulating film (103b), a second insulating film (104) and a second conductor group (105). The first conductor group forms the source (5) and drain (6) of a thin film transistor (3) a pixel electrode (4) and a data line (1). One (103A) of two-layered regions serves as an active region of the thin film transistor (3) and the other (103B) of the two-layered regions serves as the intersection (7) between the data (1) and scanning lines (2). The second insulating film (105) is enclosed in the gap between the two-layered regions and the first conductor group, and has substantially the same thickness as the two-layered regions. The second conductor group forms the scanning line and the part of the data line. A method of manufacturing the active matrix cell is also disclosed.

In an active matrix liquid crystal display device in which a source and gate buses are arranged in a matrix form, thin film transistors are provided at intersections of the source and gate buses and display electrodes are driven by applying voltage thereto via the thin film transistors, source bus repair conductive layers (41) are provided which extend along the source buses (19) in opposing relation thereto across an insulating layer (23).

摘要:
Circuit assembly (10) is disclosed which includes a supporting substrate (11), a plurality of conductive lines (14,16) supported on the substrate and a deposited phase-change material (12) capable of an energy induced phase change from an initially high resistance state to a relatively low resistance state placed in electrical contact with the conductive lines. The assembly also includes contact receiving means (24) connected to the conductive lines at preselected discrete locations to receive externally applied contact means (28), such as electric probes, for applying voltages across selected portions of the conductive lines. The application of such voltages can induce a phase change in portions of the phase-change material which bridge breaks ( 1 8) in the conductive lines of such circuit subassemblies, changing such portions from their high resistance state to their low resistance state, thereby forming electrically shunting conductive paths around such open circuits. There are also disclosed methods of making such circuit assemblies.
