摘要:
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 (15C) and a cathode (16) including a semi-transparent electrode (16A) 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 (15C) is multiply reflected between the anode (12) and the semi-transparent electrode (16A) to be emitted from the cathode (16). As the reflectance of the anode (12) is enhanced, the light generated in the luminescent layer (15C) 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.
