Abstract: 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.

Abstract: A light-emitting element, a bonding layer, and a frame-like partition are formed over a substrate. The partition is provided to surround the bonding layer and the light-emitting element, with a gap left between the partition and the bonding layer. A pair of substrates overlap with each other under a reduced-pressure atmosphere and then exposed to an air atmosphere or a pressurized atmosphere, whereby the reduced-pressure state of a space surrounded by the pair of substrates and the partition is maintained and atmospheric pressure is applied to the pair of substrates. Alternatively, a light-emitting element and a bonding layer are formed over a substrate. A pair of substrates overlap with each other, and then, pressure is applied to the bonding layer with the use of a member having a projection before or at the same time as curing of the bonding layer.

Abstract: 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.
