ABSTRACT:
It is an object of the present invention to provide a semiconductor device, in particular, a light emitting element which can be easily manufactured with a wet method. One feature of the invention is a light emitting device including a transistor and a light emitting element. In the light emitting element, an organic layer, a light emitting layer, and a second electrode are sequentially formed over a first electrode, and the transistor is electrically connected to the light emitting element through a wiring. Here, the wiring contains aluminum, carbon, and titanium. The organic layer is formed by a wet method. The first electrode which is in contact with the organic layer is formed from indium tin oxide containing titanium oxide.
