Abstract: A light extraction efficiency is increased in a display device having a plurality of display elements. The display device includes a first display element and a second display element over the first display element, and the first display element has a convex-concave shape. The convex-concave shape overlaps with a first opening provided in a reflective electrode of the second display element. A user can see an image that combines the display from the first display element and the display from the second display element. The convex-concave shape increases the light extraction efficiency of the first display element. The second display element is electrically connected to a transistor through a second opening provided in any layer of the first display element. The second display element can be provided close to the first display element.

Abstract: A novel element is provided. A novel film formation method is provided. A novel element manufacturing method is provided. Furthermore, a film including graphene is formed at low coat and high yield. The element includes a first electrode and a second electrode located apart from the first electrode. The first electrode and the second electrode include graphene. The film including graphene is formed through a first step of forming a film including graphene oxide over a substrate, a second step of immersing the film including graphene oxide in an acidic solution, and a third step of reducing graphene oxide included in the film including graphene oxide. Furthermore, before graphene oxide included in the film including graphene oxide is reduced, the film including graphene oxide is selectively removed by a photolithography technique.

Abstract: A yield in the step of bonding two members together is improved. A bonding apparatus includes a stage capable of supporting a first member having a sheet-like shape, a fixing mechanism capable of fixing one end portion of a second member having a sheet-like shape so that the second member overlaps with the first member, and a pressurizing mechanism capable of moving from a side of the one end portion of the second member to a side of the other end portion and spreading a bonding layer under pressure between the first member and the second member. The first member and the second member are bonded to each other.
