Patent ID: 8368072

Claim:
A display device comprising: a pixel portion comprising a plurality of pixels over a substrate, wherein each of the pixels provided with a pixel electrode, wherein the pixel electrode is connected to the semiconductor element, and wherein the semiconductor element comprises: an activation layer, a gate insulating film in contact with the activation layer, a gate electrode opposed to the activation layer through the gate insulating film, a first insulating nitride film including argon provided on an upper side of the activation layer, a first organic resin film provided over the first insulating nitride film, a second insulating nitride film including argon provided over the first organic resin film, a wiring provided over the second insulating nitride film, a second organic resin film provided over the wiring, and a third insulating nitride film including argon provided over the second organic resin film and a metal film added with Li provided over the third insulating nitride film; wherein an inner wall face of a first opening portion provided at the first organic resin film is covered by the second insulating nitride film, further comprising: a second opening portion provided at a laminated layer body including the gate insulating film, the first insulating nitride film and the second insulating nitride film on an inner side of the first opening portion; wherein the activation layer and the wiring are connected through the first opening portion and the second opening portion; and wherein the pixel electrode is provided at a layer on a lower side of the activation layer and connected to the semiconductor element through the wiring.
