Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor device in which a defect in signal writing to a transistor, which is caused by voltage drop or signal delay due to wiring resistance, is prevented, and to provide, for example, a display device which achieves high display quality by preventing a defect in grayscale caused by a defect in writing to a transistor provided in a display of the display device.SOLUTION: A transistor may be manufactured by connecting a highly purified oxide semiconductor having a wide band gap and a low carrier concentration to wiring including copper having low wiring resistance. Not only off current of the transistor can be reduced by using the oxide semiconductor having the wide band gap, but also a ratio of on current to the off current can be enlarged by using the highly purified oxide semiconductor having the low carrier concentration and using a so-called normally off transistor having positive threshold voltage.SELECTED DRAWING: Figure 1
