The present invention relates to an electroluminescent element formed by placing
a luminescing substance between an anode and a cathode, such that when electrical
energy is applied to the element, light is emitted having a peak wavelength of
at least 580 nm. The luminescing substance comprises a fluorescent compound have
a fluorescent maximum at about 540 nm or above and a compound having a pyrromethene
structure (I) or metal complexes thereof.
