Abstract: A light-emitting device or a display device that is less likely to be broken is provided. Provided is a light-emitting device including an element layer and a substrate over the element layer. At least a part of the substrate is bent to the element layer side. The substrate has a light-transmitting property and a refractive index that is higher than that of the air. The element layer includes a light-emitting element that emits light toward the substrate side. Alternatively, provided is a light-emitting device including an element layer and a substrate covering a top surface and at least one side surface of the element layer. The substrate has a light-transmitting property and a refractive index that is higher than that of the air. The element layer includes a light-emitting element that emits light toward the substrate side.

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.
