Abstract
Provided is a method of manufacturing an organic electroluminescence display apparatus including an organic electroluminescence device formed on a substrate, the organic electroluminescence device including a first electrode and a second electrode, at least one of which is transparent, and an organic emission layer formed between the first electrode and the second electrode, the organic emission layer being for emitting light by application of a current. Aging is performed until a rate of change in current efficiency of the organic electroluminescence device per unit time at a predetermined luminance or the amount of change per unit time in the rate of change in current efficiency of the organic electroluminescence device per unit time falls within a predetermined range.
