PROBLEM TO BE SOLVED: To provide a light-emitting device in which a plurality of kinds of circuits are formed on the same substrate, and a plurality of kinds of thin film transistors are provided so as to correspond to characteristics of the plural kinds of the circuits.SOLUTION: As a thin film transistor for a pixel, an inverted coplanar thin transistor comprising an oxide semiconductor layer overlapping a source electrode layer and a drain electrode layer is used. As a thin film transistor for a driver circuit, a channel-etch type thin film transistor is used. At a position which overlaps a light-emitting element electrically connected to the thin film transistor for a pixel, a color filter layer is formed between the thin film transistor and the light-emitting element. |
