Provided are an organic electroluminescence device capable of enhancing reflectance of an anode, thereby resulting in improved light-emitting efficiency and a method of manufacturing the same. An anode ( 12 ), a thin film layer for hole injection ( 13 ), an insulating layer ( 14 ), an organic layer ( 15 ) including a luminescent layer ( 15 C) and a cathode ( 16 ) including a semi-transparent electrode ( 16 A) are laminated in order on a substrate ( 11 ). The anode ( 12 ) comprises silver which is a metal with high reflectance or an alloy including silver, and the thin film layer for hole injection ( 13 ) comprises chromium oxide or the like. Light generated in the luminescent layer ( 15 C) is multiply reflected between the anode ( 12 ) and the semi-transparent electrode ( 16 A) to be emitted from the cathode ( 16 ). As the reflectance of the anode ( 12 ) is enhanced, the light generated in the luminescent layer ( 15 C) can be efficiently emitted. An alloy comprised in the anode ( 12 ) preferably includes silver, palladium and copper, and a silver content is preferably 50% by mass or over. |
