- 5. The electroluminescent element of claim 3, wherein the wavelength of a maximum emission of the light emitted from said inorganic fluorescent substance is within a range of from 400 nm to 700 nm.
- 6. The electroluminescent element of claim 3, wherein the wavelength of a maximum emission of the light emitted from said inorganic fluorescent substance is within a range of from 600 nm to 700 nm.
- 7. The electroluminescent element of claim 3, wherein the wavelength of a maximum emission of the light emitted from the electroluminescent material is not more than 430 nm.
- 8. The electroluminescent element of claim 3, wherein the wavelength of a maximum emission of light emitted from the electroluminescent material is within a range of from 400 to 430 nm.
- 9. The electroluminescent element of claim 3, wherein the electroluminescent material is selected from the group consisting of the following compounds:
- 10. An electroluminescent element which comprises an electroluminescent material and a rare earth metal complex capable of emitting light having a wavelength of maximum emission different from that of light emitted from the electroluminescent material upon absorption of the light emitted from the electroluminescent material and the electroluminescent material is a compound represented by the following Formula C1:
Formula C1 78wherein Ar51 is an aryl group or an aromatic heterocyclic group; n is an integer of from 0 to 6; L21, L22, L23, L24, L25 and L26 are a group of atoms necessary to form a 6-member nitrogen-containing aromatic heterocyclic group, provided that at least one of L21, L22, L23, L24, L25, and L26 is ═N— or —N(R51)—; R51 is a hydrogen atom or a substituent, provided that at least one of Ar51 and R51 is a biaryl group having a bond capable of giving an internal rotational isomerism or a group making the biaryl group, provided that adjacent substituent groups existing in the molecule represented by formula C1 may be condensed with each other to form a ring.
