摘要： A highly reliable flexible light-emitting device is provided. The light-emitting device includes a first flexible substrate, a second flexible substrate, a light-emitting element between the first flexible substrate and the second flexible substrate, a first bonding layer; and a second bonding layer in a frame shape surrounding the first bonding layer. The first bonding layer and the second bonding layer are between the second flexible substrate and the light-emitting element. The light-emitting element includes layer containing a light-emitting organic compound between the pair of electrodes. The second bonding layer has a higher gas barrier property than the first bonding layer.

摘要： A display panel or a display device with high display quality is provided. The display panel includes a light-emitting element, an insulating layer, a protective layer, and a conductive layer. The light-emitting element includes a first electrode, a light-emitting layer, and a second electrode. The light-emitting element emits light to the protective layer side. The insulating layer includes a first opening overlapping with the first electrode. The insulating layer covers an end portion of the first electrode. The light-emitting layer overlaps with the first electrode through the first opening. The second electrode is positioned over the light-emitting layer. The protective layer is over and in contact with the second electrode. The protective layer functions as a protective layer of the light-emitting element. The protective layer includes a second opening overlapping with the insulating layer. The conductive layer is connected to the second electrode through the second opening. The conductive layer functions as an auxiliary wiring of the second electrode.

摘要： A method for exposing an electrode terminal covered with an organic film in a light-emitting device without damaging the electrode terminal is provided. In a region of the electrode terminal to which electric power from an external power supply or an external signal is input, an island-shaped organic compound-containing layer is formed and the organic film is formed thereover. The organic film is removed by utilizing low adhesion of an interface between the organic compound-containing layer and the electrode terminal, whereby the electrode terminal can be exposed without damage to the electrode terminal.

摘要： A method for manufacturing a display device is provided. The method includes forming a display element interposed between a first substrate and a second substrate and peeling the second substrate from the first substrate so that an electrode, which is located between the first and second substrates and to be connected to an external electrode, is exposed simultaneously with the peeling of the second substrate.

摘要： To improve the yield in a peeling process and improve the yield in a manufacturing process of a flexible light-emitting device or the like, a peeling method includes a first step of forming a peeling layer over a first substrate, a second step of forming a layer to be peeled including a first layer in contact with the peeling layer over the peeling layer, a third step of curing a bonding layer in an overlapping manner with the peeling layer and the layer to be peeled, a fourth step of removing part of the first layer overlapping with the peeled layer and the bonding layer to form a peeling starting point, and a fifth step of separating the peeling layer and the layer to be peeled. The peeling starting point is preferably formed by laser light irradiation.
