Abstract

To provide a display device capable of performing image processing. Each pixel is provided with a memory circuit in which desired correction data is retained. The correction data is generated by calculation in an external device and written to each pixel. The correction data is added to image data by capacitive coupling and supplied to a display element. Thus, the display element can display a corrected image. Through the correction, image upconversion can be performed, or image quality decreased because of variations in pixel transistor characteristics can be corrected.
