Abstract
In a display device, a picture element capacitor is connected to a light emitting element provided in each picture element. This picture element capacitor is connected to a signal source through a switching element. The picture element is charged, by the signal source, with a signal charge corresponding to an input signal, through the closure of the switching element during some period of time. The signal charge charged into the picture element capacitor is supplied to the light emitting element, whereby the element emits lights.
