1. A display device comprising:
a substrate;
a pixel area, the pixel area comprising at least one pixel, the at least one pixel comprising at least one thin film transistor;
a peripheral area adjacent to the pixel area;
a terminal area adjacent to the peripheral area;
a first interlayer insulating film over the at least one thin film transistor and the substrate, wherein the pixel area is surrounded by a first opening in the first interlayer insulating film within the peripheral area;
a wiring line connected to the at least one thin film transistor, wherein the first interlayer insulating film is over the wiring line;
a second interlayer insulating film over the first interlayer insulating film, wherein the pixel area is surrounded by a second opening in the second interlayer insulating film within the peripheral area; and
a third opening in the first interlayer insulating film and the second interlayer insulating film within the terminal area exposes the wiring line.
