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 S1in a region where a drain bus line220completely covers a gate bus line218to form a cut portion longer than the width of the gate bus line218adjacent to an inter-layer short-circuit290such that it splits an intersecting portion of the drain bus line220into two parts as shown in FIG.5b. Next, as shown in FIG.5c, slits S2and S3are respectively used for second and third cycles of laser irradiation to cut the drain bus line220at both ends of the cut portion (indicated by S1), thereby isolating the inter-layer short-circuit290of the drain bus line220.
