摘要：
An object is, in a structure where switch circuits in a signal line driver circuit is placed over the same substrate as a pixel portion, to reduce the size of transistors in the switch circuits and to reduce load in the circuits during charging and discharging of signal lines due to the supply of data. A display device is provided which includes a pixel portion receiving a video signal, and a signal line driver circuit including a switch circuit portion configured to control output of the video signal to the pixel portion. The switch circuit portion includes a transistor over an insulating substrate. The transistor has a field-effect mobility of at least 80 cm2/Vs or more. The transistor includes an oxide semiconductor layer.
