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. | 02-26-2015 |
