Abstract (en)
An electroluminescent device having a light-emitting surface, comprising a layer (4) of phosphor (4a) capable of producing a luminescence and directing the luminescence to the light-emitting surface when the layer of phosphor is excited by a voltage, and a chromatic light converter filter (5) converting the luminescence into a light of a color different from the color of the luminescence. The chromatic light converter filter is provided on a light-emitting surface side of the electroluminescent device. The chromatic light converter filter is a film made of a transparent resin and the organic fluorescent pigment mixed with the transparent resin. The electroluminescent device commercially can be used outdoors. <IMAGE>
