<p>A device for driving capacitive light emitting elements includes a plurality of electrical charge recovery switches that send a current corresponding with an electrical charge, which has accumulated in a capacitor, individually to a plurality of drive electrodes connected to the respective capacitive light emitting elements. The electrical charge recovery switches also supply a current corresponding with the electrical charge that has accumulated in each of the capacitive light emitting elements to the capacitor individually via each of the drive electrodes. The driver device also includes a plurality of output buffers that apply a pixel-data-dependent voltage to the drive electrodes. It is determined, for each drive electrode, whether the voltage of the drive electrode has shifted from a high voltage to a low voltage or from a low voltage to a high voltage on the basis of the pixel data. If the voltage shift has occurred on the drive electrode concerned, the associated electric charge recovery switch is set to the ON state over a predetermined period. If no voltage shift has occurred, the electrical charge recovery switch is set to the OFF state.
