Abstract:
A display device that can correct the threshold voltage of a driving transistor without a correction of image data is provided. A display device including a pixel provided with a driving transistor, a display element, and a memory circuit and a correction data generation circuit is related. One of a source and a drain of the driving transistor is electrically connected to one electrode of the display element, and a gate of the driving transistor is electrically connected to the memory circuit. In a first period, the correction data generation circuit generates correction data that is data for correcting the threshold voltage of the driving transistor. In a second period, first data is written to the memory circuit. In a third period, second data is supplied to the pixel, whereby third data in which the second data is added to the first data is generated. In a fourth period, an image corresponding to the third data is displayed by the display element.
