Claim:
1. A display device comprising: a plurality of scanning lines and a plurality of signal lines that mutually intersect; a plurality of pixel circuit thin-film transistors provided at a plurality of pixels partitioned by the plurality of scanning lines and the plurality of signal lines; a common scanning interconnect that electrically connects between the plurality of scanning lines; and a plurality of protective elements that electrically connect between the common scanning interconnect and each of the plurality of scanning lines, wherein at least a part of a plurality of connecting interconnects that electrically connect the common scanning interconnect with the plurality of protective elements are constituted by interconnects on the same layer as the signal lines, a plurality of pixel circuit semiconductor layers constituting the plurality of pixel circuit thin-film transistors and each of the plurality of scanning lines overlap when seen in plan view, a plurality of semiconductor layers on the same layer as the pixel circuit semiconductor layers and a common interconnect that intersects with the plurality of scanning lines overlap when seen in plan view, and the surface area of overlapping parts between the plurality of pixel circuit semiconductor layers and at least one of the plurality of scanning lines and the surface area overlapping parts between the plurality of semiconductor layers and the common interconnect are substantially equal.
