Abstract
An organic electroluminescence device of multi-photon emission mode which includes plural light emission layers and at least one charge generation layer between a pair of electrodes, arranged in a film thickness direction thereof, wherein the charge generation layer includes at least one p-doped layer and at least one n-doped layer, and further includes an alkali metal layer and a layer containing a hole transport material between the p-doped layer and the n-doped layer. An organic electroluminescence device of multi-photon emission mode exhibiting little unevenness in luminance even in a large-area format electroluminescence device is provided.
