Abstract

A display device capable of improving image quality is provided. The display device includes a first circuit, a pixel, and a wiring. The first circuit has a function of supplying data to the wiring and a function of making the wiring floating to hold the data. The pixel has a function of taking in the data twice from the wiring and performing addition. The pixel can perform the first writing of the data in a period during which the data is supplied to the wiring, and can perform the second writing of the data in a period during which the data is held in the wiring. Therefore, by one lime of data charging to a source line, a data potential larger than or equal to an output voltage of a source driver can be supplied to a display element.
