Abstract:
1. An organic electroluminescence display device comprising: a plurality of anode electrodes arranged in a matrix; a physically-unitary common layer having a plurality of light emission regions respectively corresponding to each of the anode electrodes, the physically-unitary common layer being formed on the anode electrodes and including at least one constituent-layer made of an organic material; a driving circuitry configured to selectively provide driving current to the anode electrodes such that each of the light emission regions selectively emits light; a metal interconnect directly electrically connected to the physically-unitary common layer; a common cathode electrode formed on the physically-unitary common layer, wherein the driving circuitry is configured to: apply a first potential to the common cathode electrode, and apply a second potential to the metal interconnect, where the second potential is set such that, when the second potential is applied to the anode electrode corresponding to a given one of the light emission regions and the first potential is applied to the common cathode electrode, the given one of the light emission regions does not emit light.
