It is an object to provide a semiconductor device typified by a display device having a favorable display quality, in which parasitic resistance generated in a connection portion between a semiconductor layer and an electrode is suppressed and an adverse effect such as voltage drop, a defect in signal wiring to a pixel, a defect in grayscale, and the like due to wiring resistance are prevented. In order to achieve the above object, a semiconductor device according to the present invention may have a structure where a wiring with low resistance is connected to a thin film transistor in which a source electrode and a drain electrode that include metal with high oxygen affinity are connected to an oxide semiconductor layer with a suppressed impurity concentration. In addition, the thin film transistor including the oxide semiconductor may be surrounded by insulating films to be sealed.

It is an object of the present invention to provide a method for fabricating a light emitting device, in which brightness gradient due to potential drop of a counter electrode can be prevented from being observed and an auxiliary electrode can be formed without increasing the number of steps, even when the precision of a light emitting device is improved. It is another object of the invention to provide a light emitting device fabricated according to the method. The light emitting device has a light emitting element and an auxiliary electrode in each pixel. The light emitting element includes a first electrode, a second electrode, an electroluminescent layer provided between the first and the second electrodes. Further, the first electrode is overlapped with the electroluminescent layer and the second electrode formed over an insulating film by means of a first opening formed in the insulating film. Still further, the auxiliary electrode is overlapped with the second electrode by means of a second opening formed over the second insulating film.
