摘要： A semiconductor device including an oxide semiconductor in which on-state current is high is provided. The semiconductor device includes a first transistor provided in a driver circuit portion and a second transistor provided in a pixel portion; the first transistor and the second transistor have different structures. Furthermore, the first transistor and the second transistor are transistors having a top-gate structure. In an oxide semiconductor film of each of the transistors, an impurity element is contained in regions which do not overlap with a gate electrode. The regions of the oxide semiconductor film which contain the impurity element function as low-resistance regions. Furthermore, the regions of the oxide semiconductor film which contain the impurity element are in contact with a film containing hydrogen. The first transistor provided in the driver circuit portion includes two gate electrodes between which the oxide semiconductor film is provided.

摘要： A novel display device that is highly convenient with low power consumption is provided. The display device includes a display element including a liquid crystal layer, a display element including a light-emitting layer, and a pixel circuit. Electrodes of the display element including the liquid crystal layer and the display element including the light-emitting layer are electrically connected to the pixel circuit. The electrode of the display element including the liquid crystal layer includes a reflective film including an opening. The pixel circuit includes a transistor including a semiconductor film. The number of insulating films in a region overlapping with the opening is smaller than that of insulating films overlapping with the semiconductor film. In addition, the display element including the light-emitting layer includes two light-emitting elements. The number of optical elements overlapping with one light-emitting element is smaller than that of optical elements overlapping with the other light-emitting element.
