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.

Abstract: In a thin film transistor, an increase in off current or negative shift of the threshold voltage is prevented. In the thin film transistor, a buffer layer is provided between an oxide semiconductor layer and each of a source electrode layer and a drain electrode layer. The buffer layer includes a metal oxide layer which is an insulator or a semiconductor over a middle portion of the oxide semiconductor layer. The metal oxide layer functions as a protective layer for suppressing incorporation of impurities into the oxide semiconductor layer. Therefore, in the thin film transistor, an increase in off current or negative shift of the threshold voltage can be prevented.
