Abstract
A display device including a peripheral circuit portion with high operation stability. The display device includes a first substrate and a second substrate. A first insulating layer is on a first plane of the first substrate, and a second insulating layer is on a first plane of the second substrate. An area of the first plane of the first substrate is the same as an area of the first plane of the second substrate. The first plane of the first substrate and the first plane of the second substrate face each other. A bonding layer is between the first insulating layer and the second insulating layer. A protection film is in contact with the first substrate, the first insulating layer, the bonding layer, the second insulating layer, and the second substrate.
