Japanese Published Patent Application No. When the display region and the peripheral circuit are formed simultaneously, the manufacturing cost can be reduced. For example, Patent Document 1 discloses a technique of using oxide semiconductor transistors in the display region and the peripheral circuit.
In addition, these displays are very important for portable displays and have been necessary for portable terminals.įurthermore, display devices in which a display region (a pixel portion) and a peripheral circuit (a driver portion) are provided in the same substrate have been widely used. BACKGROUND ARTĭisplays including thin film transistors have been widely spread and indispensable to our life. An imaging device, a display device, a liquid crystal display device, a light-emitting device, an electro-optical device, a power generation device (including a thin film solar cell, an organic thin film solar cell, and the like), and an electronic device may each include a semiconductor device. A semiconductor element such as a transistor, a semiconductor circuit, an arithmetic device, and a memory device are each an embodiment of a semiconductor device. In this specification and the like, a semiconductor device generally means a device that can function by utilizing semiconductor characteristics. Specifically, examples of the technical field of one embodiment of the present invention disclosed in this specification include a semiconductor device, a display device, a light-emitting device, a power storage device, a memory device, an input device, an input/output device, a method for driving any of them, and a method for manufacturing any of them. In addition, one embodiment of the present invention relates to a process, a machine, manufacture, or a composition of matter. The technical field of the invention disclosed in this specification and the like relates to an object, a method, or a manufacturing method.
Note that one embodiment of the present invention is not limited to the above technical field. One embodiment of the present invention relates to a display device and a manufacturing method of the display device.
