A luminescence device is constituted by a substrate, a first electrode disposed
on the substrate, at least one organic luminescence function layer disposed on
the first electrode, a second electrode disposed on the above at least one organic
luminescence function layer, and an oxygen absorbent disposed between the substrate
and the second electrode or between the first and second electrodes. To the luminescence
device, a voltage is applied between the first and second electrodes to cause phosphorescence
from at last one layer constituting the above-mentioned at least one organic luminescence
function layer preferably containing the oxygen absorbent. The oxygen absorbent
may be formed in a layer disposed at a region other than pixel portions.
