Abstract:
1. An organic electroluminescence device provided with a first electrode composed of a transparent electrode or a semitransparent electrode, a second electrode facing the first electrode, and at least one organic layer set between the first and second electrodes, characterized in that: the organic electroluminescence device comprises an auxiliary electrode provided with openings, which is electrically connected to the first electrode and composed of a material having a lower electrical resistance value than that of the first electrode; and the auxiliary electrode is formed on the surface of the first electrode so as to have the regions defined based on lattice points determined by a quasi-periodic two-dimensional array as the openings; wherein the auxiliary electrode is formed on Voronoi edges of Voronoi tessellation using the lattice points as generating points so that the Voronoi regions of the Voronoi tessellation are the openings.
