The display device includes a first pixel, a second pixel, and a third pixel each including a first transistor, a second transistor, and a light-emitting element. In each of the first to third pixels, a first terminal of the first transistor is electrically connected to a signal line, a second terminal of the first transistor is electrically connected to a gate of the second transistor, a first terminal of the second transistor is electrically connected to a power supply line and a second terminal of the first transistor is electrically connected to the light-emitting element. A gate of the first transistor in the first pixel is electrically connected to a first scan line. A gate of the first transistor in the second pixel is electrically connected to a second scan line. A gate of the first transistor in the third pixel is electrically connected to a third scan line.
