The display device includes a signal line and a pixel. The pixel includes a first switching element, a capacitor having a first electrode which is electrically connected to the signal line through the first switching element, a display element electrically connected to the first electrode of the capacitor, a second switching element, and an electric charge supply terminal electrically connected to a second electrode of the capacitor through the second switching element. A potential difference between a potential of the signal line and a potential of the electric charge supply line is applied to the capacitor. Voltage of the capacitor at the time of writing is set higher than that of the display element. Accordingly, drop in voltage held in the capacitor due to degradation of the first switching element is reduced, and desired voltage applied to the display element is maintained.
