Abstract
The present invention provides a semiconductor device by which a light-emitting device that is unlikely to cause defects such as a short circuit, can be manufactured. One feature of a semiconductor device of the present invention is to include an electrode that serves as an electrode of a light-emitting element. The electrode includes a first layer and a second layer. Further, end portions of the electrode are covered with a partition layer having an opening portion. Moreover, a part of the electrode is exposed by the opening portion of the partition layer. One feature of a semiconductor device of the present invention is to include an electrode that serves as an electrode of a light-emitting element and a transistor. The electrode and the transistor are connected electrically to each other. The electrode includes a first layer and a second layer. Further, end portions of the electrode are covered with a partition layer having an opening portion. Moreover, the second layer is exposed by the opening portion of the partition layer.
