Abstract:
1. An active matrix substrate comprising: a substrate; at least one line formed on the substrate; and an insulating layer for electrically insulating a layer formed on the at least one line from the at east one line, the at least one line having a multilayered structure comprising (i) a line in a top layer, (ii) a middle line directly below the line in the top layer, the line in the top layer protruding, in a direction in which the line in the top layer extends, more than the line directly below the line in the top layer as viewed in a cross sectional direction, and (iii) a bottom line located directly below the middle line, the bottom line protruding, in the direction in which the line in the top layer extends, more than the line in the top layer as viewed in the cross sectional direction; wherein in a region of the substrate, the insulating layer not being provided on an upper surface of the at least one line, the upper surface being exposed, the insulating layer being provided on the substrate with a thickness of not more than a film thickness of the at least one line so as to have contact with at least an edge face of the line directly below the line in the top layer, the edge face being on an extension of a longitudinal direction of the line directly below the line in the top layer.
