Patent ID: 7411215

Claim:
A display device comprising a pixel portion having a plurality of pixels, wherein each of the pixels is provided with a pixel electrode, and wherein the pixel electrode is connected to a semiconductor element over a substrate, 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 provided over the activation layer, an organic resin film provided over the first insulating nitride film, a second insulating nitride film provided over the organic resin film, and a wiring provided over the second insulating nitride film; wherein an inner wall face of a first opening portion formed in the organic resin film is covered by the second insulating nitride film; wherein a second opening portion is formed in a laminated layer body including the gate insulating film, the first insulating nitride film and the second insulating nitride film inside the first opening portion; wherein the activation layer and the wiring are connected through the first opening portion and the second opening portion; wherein the pixel electrode is connected to the semiconductor element through the wiring electrically; wherein a first part of an insulating film is formed over the pixel electrode; and wherein the activation layer is formed over a second part of the insulating film.
