Abstract
A highly reliable light-emitting device is provided. A light-emitting device in which problems due to a metal mask are prevented is provided. A light-emitting devi in which a problem due to the resistance of an upper electrode layer of a light-emitting element is prevented is provided. An electrode layer is provided over a substrate in advance, and an EL layer and an upper electrode layer are formed in the same pattern without use of a metal mask so as to overlap with the electrode layer. After that, the electrode layer is electrically connected to the upper electrode layer. As a connection method, a laser light irradiation method, a method in which physical pressure is applied, a method in which heating is performed under the state where physical pressure is applied, or the like is used.
