Abstract

A novel display device where a light-emitting element is turned on by a triangle wave is provided. One embodiment of the present invention is a method for driving a display device including a first pixel, a second pixel, a first wiring, a second wiring, and a third wiring. The first wiring is electrically connected to the first pixel and the second pixel. The second wiring and the third wiring are electrically connected to the first pixel and the second pixel, respectively. At a first time, the first pixel reaches the maximum luminance corresponding to first display data and the second pixel reaches the maximum luminance corresponding to second display data. The first pixel and the second pixel are initialized at a second time different from the first time by input of a reset signal to the first wiring to stop light emission.
