Abstract
Provided is a wiring structure having: a first wiring; a first insulating film over the first wiring; a second wiring over the first insulating film, the second wiring intersecting the first wiring; an electrode over the first insulating film, the electrode being spaced from the second wiring; and a second insulating film over the second wiring and the electrode. The entire electrode overlaps with the first wiring. A top surface of the first insulating film is entirely in contact with the second insulating film over the first wiring and between the second wiring and the electrode.
Claims20
A wiring structure comprising:
- a first wiring;
- a first insulating film over the first wiring;
- a second wiring over the first insulating film and intersecting the first wiring;
- an electrode over the first insulating film and spaced from the second wiring;
- and
- a second insulating film over the second wiring and the electrode,
- wherein an entire region of the electrode overlaps with the first wiring in a plan view, and
- a top surface of the first insulating film is entirely in contact with the second insulating film in a region immediately over the first wiring and between the second wiring and the electrode.
A display device comprising:
- a transistor including a semiconductor film, a gate insulating film over the semiconductor film, a gate over the gate insulating film, a first interlayer insulating film over the gate, a second interlayer insulating film over the first interlayer insulating film, a first terminal over the second interlayer insulating film, and a second terminal over the second interlayer insulating film;
- a leveling film over the transistor;
- a display element over the leveling film and electrically connected to the second terminal;
- and
- a first wiring sandwiched between the first interlayer insulating film and the second interlayer insulating film and electrically connected to the first terminal,
- wherein the first wiring has a first opening, and the second interlayer insulating film is in contact with the leveling film and the first interlayer insulating film through the first opening.
A display device comprising:
- a transistor including a semiconductor film, a gate insulating film over the semiconductor film, a gate over the gate insulating film, a first interlayer insulating film over the gate, a second interlayer insulating film over the first interlayer insulating film, a first terminal over the second interlayer insulating film, and a second terminal over the second interlayer insulating film;
- a display element electrically connected to the second terminal;
- and
- a first wiring sandwiched between the first interlayer insulating film and the second interlayer insulating film and electrically connected to the first terminal,
- wherein the entire first terminal is surrounded by an outline of the first wiring.
