Display and method for repairing defects thereof

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 Sin a region where a drain bus linecompletely covers a gate bus lineto form a cut portion longer than the width of the gate bus lineadjacent to an inter-layer short-circuitsuch that it splits an intersecting portion of the drain bus lineinto two parts as shown in FIG.Next, as shown in FIG.slits Sand Sare respectively used for second and third cycles of laser irradiation to cut the drain bus lineat both ends of the cut portion (indicated by S), thereby isolating the inter-layer short-circuitof the drain bus line
