Claim 14:
15. The manufacturing method of an active matrix substrate according to claim 14,
wherein the active matrix substrate includes a plurality of wiring line overlapping portions arranged in the non-display region,
in each of the plurality of wiring line overlapping portions, one of first wiring lines formed of the first conductive film and one of second wiring lines formed of the second conductive film overlap each other with the gate insulating layer interposed between the one of first wiring lines and the one of second wiring lines,
the forming of the interlayer insulating layer (E) includes forming a first opening in the inorganic insulating layer and the organic insulating layer that exposes part of the one of second wiring lines in at least one among the plurality of wiring line overlapping portions, and
the forming of the third metal layer (F) includes forming a plurality of protective conductive layers each separated one another from the third conductive film, and each of the plurality of protective conductive layers is arranged in the first opening and on part of an upper face of the organic insulating layer, and is in contact with the part of the one of second wiring lines in the first opening.
