Abstract: An object of one embodiment of the present invention is to provide a more convenient highly reliable light-emitting device which can be used for a variety of applications. Another object of one embodiment of the present invention is to manufacture, without complicating the process, a highly reliable light-emitting device having a shape suitable for its intended purpose. In a manufacturing process of a light-emitting device, a light-emitting panel is manufactured which is at least partly curved by processing the shape to be molded after the manufacture of an electrode layer and/or an element layer, and a protective film covering a surface of the light-emitting panel which is at least partly curved is formed, so that a light-emitting device using the light-emitting panel has a more useful function and higher reliability.

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: It is an object of one embodiment of the present invention to manufacture a light-emitting display device by simplifying a manufacturing process of a transistor, without an increase in the number of steps as well as the number of photomasks as compared to those in the conventional case. A step for processing a semiconductor layer into an island shape is omitted by using a high-resistance oxide semiconductor which is intrinsic or substantially intrinsic for the semiconductor layer, used to form transistors. Formation of an opening in the semiconductor layer or an insulating layer formed over the semiconductor layer and etching of an unnecessary portion of the semiconductor layer are performed at the same time; thus, the number of photolithography steps is reduced.
