摘要：
To reduce the thickness of a lighting device which uses an electroluminescent material and to simplify the structure of a lighting device which uses an electroluminescent material, in the lighting device of the present invention: a terminal electrically connecting a light-emitting element included in the lighting device to the outside is formed over the same surface of a substrate as the light-emitting element; and the terminal is formed at the center of the substrate while the light-emitting element is stacked. In addition, the lighting device has a structure in which the light-emitting element is not easily deteriorated.
