An object of the present invention is to provide a light-emitting device in which plural kinds of circuits are formed over the same substrate, and plural kinds of thin film transistors are provided in accordance with characteristics of the plural kinds of circuits. An inverted-coplanar thin film transistor, an oxide semiconductor layer of which overlaps with a source and drain electrode layers, and a channel-etched thin film transistor are used as a thin film transistor for a pixel and a thin film transistor for a driver circuit, respectively. Between the thin film transistor for a pixel and a light-emitting element, a color filter layer is provided so as to overlap with the light-emitting element which is electrically connected to the thin film transistor for a pixel. |
