Provided is a method for manufacturing a highly reliable display device. The method includes steps of providing a first layer, a first insulating layer, an electrode, and a second insulating layer over a first surface of a first substrate; removing a part of the second insulating layer to provide a first opening; providing a display element and a second layer over the second insulating layer; providing a third layer and a third insulating layer over a second surface of a second substrate; removing part of the third layer and part of the third insulating layer to provide a second opening; overlapping the first substrate and the second substrate with a bonding layer positioned therebetween such that the first surface and the second surface face each other and the first opening and the second opening have an overlap region; separating the first substrate and the first layer from the first insulating layer; providing a third substrate such that the first insulating layer and the third substrate overlap with each other; separating the second substrate, part of the bonding layer, part of the second layer, and the third layer from the third insulating layer; and providing a fourth substrate such that the third insulating layer and the fourth substrate overlap with each other. |
