Abstract:
1. A light-emitting device comprising: a substrate; a silicon oxide layer over the substrate; a nitrogen-containing layer over the silicon oxide layer; an oxide film over the nitrogen-containing layer, the oxide film comprising a halogen element; a pixel portion comprising: a driver circuit configured to output an analog video signal into a gate electrode of the first transistor such that an amount of a current flowing in the light-emitting element is changed in accordance with a potential applied to the gate electrode of the first transistor, the driver circuit comprising a second transistor comprising a second semiconductor layer comprising a second channel formation region, wherein each of the first semiconductor layer and the second semiconductor layer is a single-crystal semiconductor layer provided over the substrate with the silicon oxide layer, the nitrogen-containing layer and the oxide film provided therebetween.
