Abstract
A thin-film transistor (TFT) array substrate includes a driving TFT, a storage capacitor, a first wire, a first interlayer insulating film, a second interlayer insulating film, and a second wire. The storage capacitor has a first electrode connected to a driving gate electrode of the driving TFT and a second electrode on and insulated from the first electrode. The first wire is on a same layer as the driving gate electrode. The first interlayer insulating film covers the first electrode and the first wire. The second interlayer insulating film is on the first interlayer insulating film and includes an opening that exposes part of the first interlayer insulating film. The second wire is on the second interlayer insulating film and at least partially overlaps the first wire. The second electrode is in the opening of the second interlayer insulating film.
