| 1. A method of manufacturing an organic electroluminescence display device, comprising:
(a) forming a lower electrode over a substrate;
(b) forming an organic hole injection layer over the lower electrode, after step (a);
(c) forming an organic light emitting layer over the organic hole injection layer, after step (b);
(d) forming an insulating layer functioning as a partition between neighboring pixels, after step (c);
(e) forming an electron injection layer over the organic hole injection layer and the insulating layer, after step (d); and
(f) forming a cathode on the electron injection layer, after step (e).
