Abstract

An array substrate includes gate lines made of a first metal film, source lines made of a second metal film disposed such that a gate insulating film is interposed between the second metal film and the first metal film, the source lines extending to intersect the gate lines, auxiliary lines made of the first metal film, the auxiliary lines being arranged such that a pair of auxiliary lines sandwich the gate line therebetween and extending in parallel with the source lines to at least partly overlap the source lines, respectively, and bridge lines made of a third metal film disposed such that a first inter-layer film located opposite to the gate insulating film is interposed between the third metal film and the second metal film, the bridge lines being arranged to lie astride the gate lines, respectively, to electrically connect the source lines to pairs of the auxiliary lines.
