Abstract:
1. A display device comprising: a transistor over a substrate, the transistor including a gate insulating film between an active layer and a gate electrode; a pair of first wirings over the substrate; a second wiring between the pair of first wirings; an interlayer insulating film over the pair of first wirings and the second wiring; and a third wiring over the interlayer insulating film, wherein the interlayer insulating film includes a plurality of contact holes, wherein a diameter of each of the plurality of contact holes is smaller than a gap between the plurality of contact holes, wherein the third wiring is in contact with the pair of first wirings via the plurality of contact holes, wherein the third wiring includes a portion extending in parallel with the pair of first wirings, and wherein the pair of first wirings and the second wiring are provided over and in contact with the gate insulating film.
