Abstract: To provide a semiconductor device including a narrowed bezel obtained by designing a gate driver circuit. A gate driver of a display device includes a shift register unit, a demultiplexer circuit, and n signal lines. By connecting the n signal lines for transmitting clock signals to one stage of the shift register unit, (n−3) output signals can be output. The larger n becomes, the smaller the rate of signal lines for transmitting clock signals which do not contribute to output becomes; accordingly, the area of the shift register unit part is small compared to a conventional structure in which one stage of a shift register unit outputs one output signal. Therefore, the gate driver circuit can have a narrow bezel.

Abstract: An object is to reduce leakage current and parasitic capacitance of a transistor used for an LSI, a CPU, or a memory. A semiconductor integrated circuit such as an LSI, a CPU, or a memory is manufactured using a thin film transistor in which a channel fog nation region is formed using an oxide semiconductor which becomes an intrinsic or substantially intrinsic semiconductor by removing impurities which serve as electron donors (donors) from the oxide semiconductor and has larger energy gap than that of a silicon semiconductor. With use of a thin film transistor using a highly purified oxide semiconductor layer with sufficiently reduced hydrogen concentration, a semiconductor device with low power consumption due to leakage current can be realized.
