Abstract: 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.

Abstract: A semiconductor device obtains highly accurate image data regardless of the intensity of incident light. The semiconductor device includes a first photo sensor provided in a pixel, a second photo sensor provided around the pixel, and a controller for setting the drive condition of the first photo sensor in accordance with the intensity of outside light obtained by the second photo sensor. An image is taken after the sensitivity of the first photo sensor is changed in accordance with the drive condition set by the controller. Thus, in the semiconductor device, an image can be taken using the first photo sensor whose sensitivity is optimized in accordance with the intensity of incident light.
