Organic EL display device and electronic apparatus

摘要

Disclosed herein is an organic EL display device in which pixels each including an organic EL element formed by interposing an organic layer between an anode electrode and a cathode electrode are arranged in a matrix, the organic EL display device including: a common layer configured to be included in the organic EL element and be formed in the organic layer in common to the pixels; and a metal interconnect configured to surround periphery of the anode electrode and be electrically connected to the organic layer, wherein potential of the metal interconnect is set to a potential lower than potential of the anode electrode in a non-light-emission state of the organic EL element.

主权项

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.
