Abstract:
1. An active matrix substrate comprising: a plurality of scanning signal lines and data signal lines supported by a substrate; a thin film transistor provided proximate an intersecting point of the signal lines and comprising a gate electrode connected to the scanning signal line, and a source electrode connected to the data signal line; and a pixel electrode electrically connected to a drain electrode of the thin film transistor, wherein the data signal line comprises an at least partly multilinear part, the active matrix substrate comprises a wiring structure having an overlapping part of a part of the wiring structure and the multilinear part of the data signal line, an overlapping part of a part of the wiring structure and a circuit part connecting the thin film transistor to the pixel electrode, and at least one of the overlapping parts provided through an insulating film, the multilinear part of the data signal line comprising first and second substantially parallel sections that are located between TFTs of adjacent pixel regions, the first and second substantially parallel sections of the multilinear part being electrically connected during normal display operation in absence of defects but being adapted to be electrically separated upon occurrence of a defect.
