Abstract:
1. A display panel device, comprising: a luminescence element; a capacitor for holding a voltage; a driver including a gate electrode connected to a first electrode of the capacitor for driving the luminescence element to produce luminescence by passing, into the luminescence element, a drain current corresponding to the voltage held by the capacitor; a first power line for determining a potential of a drain electrode of the driver; a second power line connected to a second electrode of the luminescence element; a first switch connected to the first electrode of the capacitor for setting a reference voltage to the first electrode of the capacitor; a data line for supplying a data voltage to a second electrode of the capacitor; a second switch connected to the data line and the second electrode of the capacitor for switching between a conduction state and a non-conduction state between the data line and the second electrode of the capacitor; a wiring connected to the first electrode of the luminescence element and the second electrode of the capacitor for interconnecting the 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; and a third switch connected in series with the driver between the first electrode of the luminescence element and the first power line for determining an ON state and an OFF state of the drain current of the driver.
