摘要： An object is to provide a pixel structure of a display device including a photosensor which prevents changes in an output of the photosensor and a decrease in imaging quality. The display device has a pixel layout structure in which a shielding wire is disposed between an FD and an imaging signal line (a PR line, a TX line, or an SE line) or between the FD and an image-display signal line in order to reduce or eliminate parasitic capacitance between the FD and a signal line for the purpose of suppressing changes in the potential of the FD. An imaging power supply line, image-display power supply line, a GND line, a common line, or the like whose potential is fixed, such as a common potential line, is used as a shielding wire.

摘要： A storage element capable of retaining data even after supply of power supply voltage is stopped is provided. In the storage element retaining data in synchronization with a clock signal, with the use of a capacitor and a transistor having a channel in an oxide semiconductor layer, the data can be retained even after supply of power supply voltage is stopped. Here, when the transistor is turned off while the level of the clock signal is kept constant before the supply of power supply voltage is stopped, the data can be retained accurately in the capacitor. By applying such a storage element to each of a CPU, a memory, and a peripheral control device, supply of power supply voltage can be stopped in the entire system, so that the power consumption of the entire system can be reduced.
