Display device and electronic device

A display device comprising:

• a pixel portion comprising:
• a pixel transistor;
• a first insulating film including a silicon film including oxygen, the first insulating film covering the pixel transistor;
• a second insulating film including an acrylic-based resin material over the first insulating film;
• and
• a third insulating film including a silicon film including nitrogen over the second insulating film;
• and
• a driver circuit portion outside the pixel portion, the driver circuit portion comprising:
• a driving transistor configured to supply a signal to the pixel transistor;
• the first insulating film covering the driving transistor;
• and
• the second insulating film over the first insulating film,
• wherein the third insulating film includes an opening portion over the driving transistor,
• wherein the third insulating film does not overlap a semiconductor layer of the driving transistor,
• wherein the pixel portion and the driver circuit portion are over a substrate,
• wherein the substrate comprises a first region,
• wherein an entire region of the first region and an entire region of the pixel portion overlap each other, and
• wherein the third insulating film does not overlap any region of the substrate other than the first region.
