As the display device becomes more precise, the number of pixels increases, and the gate bow and the signal bow increase. When the gate lead and the signal lead increase, it becomes difficult to mount an IC chip having a driving circuit for driving them by bonding or the like, which increases the manufacturing cost.n n n It is driven by an inverted staggered thin film transistor having a pixel portion and a driving circuit for driving the pixel portion on the same substrate, using an oxide semiconductor, and having a channel protective layer formed on the oxide semiconductor layer which becomes a channel forming region overlapping with the gate electrode layer. Configure at least part of the circuit. In addition to the pixel portion on the same substrate, manufacturing cost is reduced by forming a driving circuit. |
