An apparatus for driving capacitive light emitting diodes which can be reduced in size. For supplying a capacitive light emitting diode with a driving pulse which varies the voltage with a predetermined amplitude through a driving line, the driving apparatus comprises a resonance current path including a capacitor, a first switching element for supplying the driving line with a current in accordance with charges accumulated on the capacitor when it is on, and a second switching element for grounding one electrode of the capacitor when it is on, thereby supplying the other electrode of the capacitor with a current in accordance with charges accumulated in the capacitive light emitting element through the driving line.
