Abstract

An electroluminescent element comprising an electroluminescent (EL) material part which emits a near ultraviolet ray of light and a fluorescent material part which absorbs the ultraviolet light emitted from the electroluminescent material and emits a fluorescence in a visible light range from blue to red. The electroluminescent element provides for emission of lights with a wide range of wavelength and three elementary colors of blue, green and red can be expressed by appropriate combinations of the organic EL material and the fluorescent material. Consequently, the electroluminescent element provides for a full color display.
