LIGHT-EMITTING DEVICE AND MANUFACTURING METHOD THEREOF - A light-emitting device in which plural kinds of circuits are formed over one substrate and plural kinds of thin film transistors in accordance with characteristics of the plural kinds of circuits are included. An inverted-coplanar thin film transistor including an oxide semiconductor layer which overlaps a source and drain electrode layers is used as a thin film transistor for a pixel, a channel-stop thin film transistor is used as a thin film transistor for a driver circuit, and a color filter layer is provided between the thin film transistor for a pixel and a light-emitting element so as to overlap the light-emitting element which is electrically connected to the thin film transistor for a pixel.
