Zusammenfassung:PROBLEM TO BE SOLVED: To provide an electroluminescence device, which generally has a little unevenness in brightness and are imparted with functions of illumination with a visual effect, such as gradation, and display of a specific pattern by intentionally imparting the electroluminescence device with unevenness in brightness. SOLUTION: The electroluminescence device includes transparent or semitransparent first and second electrodes and at least a light-emitting layer between the first and second electrodes, wherein reflectances in a surface, facing the light-emitting layer, of the second electrode have a distribution.
