1. A display device comprising:

  • a glass substrate;

    a first insulating film over the glass substrate;

    a first semiconductor film over the first insulating film;

    a second semiconductor film over the first insulating film;

    a second insulating film over the first semiconductor film and the second semiconductor film;

    a first conductive film over the second insulating film, wherein the first conductive film and the first semiconductor film overlap with each other;

    a second conductive film over the second insulating film, wherein the second conductive film and the second semiconductor film overlap with each other;

    a first silicon nitride film over the second insulating film, the first conductive film, and the second conductive film;

    an organic resin film over the first silicon nitride film;

    a second silicon nitride film over the organic resin film; and

    an electrode over the second silicon nitride film;

    wherein the first semiconductor film and the first conductive film are provided in a pixel portion,wherein the second semiconductor film and the second conductive film are provided out of the pixel portion,wherein the organic resin film comprises a first region overlapping with the first semiconductor film,wherein the organic resin film comprises a second region overlapping with the second semiconductor film,wherein the first conductive film and the second conductive film each comprise a region functioning as a gate electrode,wherein the first silicon nitride film comprises a first opening,wherein the organic resin film comprises a second opening,wherein the second silicon nitride film comprises a third opening,wherein the first opening comprises a region overlapping with the second opening,wherein the first opening comprises a region overlapping with the third opening,wherein the second opening comprises a region overlapping with the third opening,wherein the first opening is smaller than the second opening,wherein the third opening is smaller than the second opening,wherein the second silicon nitride film comprises a first region over an upper surface of the organic resin film and a second region facing a side surface of the organic resin film in the second opening,wherein the first silicon nitride film comprises a region in contact with the second silicon nitride film in the second opening,wherein the electrode is electrically connected to the first semiconductor film through the first opening and the third opening, andwherein the electrode comprises a first region facing a side surface of the first silicon nitride film in the first opening and a second region facing a side surface of the second silicon nitride film in the third opening.
