A display panel device includes a luminescence element and a capacitor. A driving transistor includes a gate that is connected to a first electrode of the capacitor. A first switch is connected to the first electrode of the capacitor for setting a reference voltage to the first electrode of the capacitor. A data line supplies a data voltage to a second electrode of the capacitor. A second switch is connected between the data line and the second electrode of the capacitor. A wiring is connected to a first electrode of the luminescence element and the second electrode of the capacitor for interconnecting a first power line and the first electrode of the luminescence element with the second electrode of the capacitor, the second switch, and the data line. A third switch is connected in series with the driver between the first electrode of the luminescence element and the first power line.
