  • Patent number: 7187423
    Abstract: It is an object of the invention to provide a display and a method for repairing defects of the same in which defects such as inter-layer short-circuits and short-circuits in a single that have occurred at steps for manufacturing the display can be easily repaired to provide a good product with a probability higher than that in the related art. Laser irradiation is carried out as a first cycle of laser irradiation by forming a slit S1 in a region where a drain bus line 220 completely covers a gate bus line 218 to form a cut portion longer than the width of the gate bus line 218 adjacent to an inter-layer short-circuit 290 such that it splits an intersecting portion of the drain bus line 220 into two parts as shown in FIG. 5b. Next, as shown in FIG. 5c, slits S2 and S3 are respectively used for second and third cycles of laser irradiation to cut the drain bus line 220 at both ends of the cut portion (indicated by S1), thereby isolating the inter-layer short-circuit 290 of the drain bus line 220.

  • Publication number: 20010028418
    Abstract: There is provided a fault repairing method for a liquid crystal display device capable of repairing simply a disconnected portion when a disconnection fault occurs in a display panel. For example, it is on the assumption that the disconnected portion is present in a data bus line. Disconnection repairing contact holes that have a width larger than that of the data bus line are formed in a protection insulating film on the data bus line on both sides of the disconnected portion respectively. Then, a laser CVD film (metal film) for covering inner surfaces of the disconnection repairing contact holes is formed by the laser CVD method, and then respective laser CVD films are connected electrically.
