Abstract
An organic electroluminescence element is provided with a first electrode composed of a transparent electrode or a semi-transparent electrode; a second electrode facing the first electrode; and at least one organic layer arranged between the first electrode and the second electrode. The organic electroluminescence device is further provided with an auxiliary electrode, which is electrically connected to the first electrode, composed of a material having a lower electrical resistance value compared with that of the first electrode and has an opening. The auxiliary electrode is formed on the surface of the first electrode to have an area fixed based on a lattice point specified by a quasi-periodic two-dimensional arrangement as the opening section.
Claims12
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.
