Abstract: As a display device has higher definition, the number of pixels is increased and thus, the number of gate lines and signal lines is increased. When the number of gate lines and signal lines is increased, it is difficult to mount IC chips including driver circuits for driving the gate lines and the signal lines by bonding or the like, whereby manufacturing cost is increased. A pixel portion and a driver circuit for driving the pixel portion are provided on the same substrate, and at least part of the driver circuit comprises a thin film transistor including an oxide semiconductor sandwiched between gate electrodes. A channel protective layer is provided between the oxide semiconductor and a gate electrode provided over the oxide semiconductor. The pixel portion and the driver circuit are provided on the same substrate, which leads to reduction of manufacturing cost.

Abstract: As a display device has a higher definition, the number of pixels, gate lines, and signal lines are increased. When the number of the gate lines and the signal lines are increased, a problem of high manufacturing cost, because it is difficult to mount an IC chip including a driver circuit for driving of the gate and signal lines by bonding or the like. A pixel portion and a driver circuit for driving the pixel portion are provided over the same substrate, and at least part of the driver circuit includes a thin film transistor using an oxide semiconductor interposed between gate electrodes provided above and below the oxide semiconductor. Therefore, when the pixel portion and the driver portion are provided over the same substrate, manufacturing cost can be reduced.

Abstract translation: 作为显示装置具有更高的清晰度，像素数，栅极线和信号线的数量增加。 当栅极线和信号线的数量增加时，由于难以通过接合等安装包括用于驱动栅极和信号线的驱动电路的IC芯片，所以制造成本更高。 用于驱动像素部分的像素部分和驱动电路设置在相同的基板上，驱动电路的至少一部分包括薄膜晶体管，该薄膜晶体管使用介于氧化物半导体上方和下方的栅电极之间的氧化物半导体。 因此，当像素部分和驱动器部分设置在相同的基板上时，可以降低制造成本。
