Abstract
According to one embodiment, a display device includes a display area and a driver. Each of pixels includes a light emitting element and a drive transistor connected in series. An image signal includes a first luminance data and a second luminance data. The first luminance data is based on an average value of a gradation value of pixels, and is common among the pixels included in said one area. The second luminance data is, based on a difference between the gradation value and the average value, an independent luminance data of each of the pixels. The driver controls a common luminance time of the pixels based on the first luminance data, and controls a current value to be supplied to the luminance element of each of the pixels based on the second luminance data.
