Title:
ELECTROLUMINESCENT DEVICE AND LIGHT-EMITTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2004/046275
Kind Code:
A1
Abstract:
An electroluminescent device fabricated by using a material suitable also for a host material, having a good film-formability and an excellent carrier transporting ability, and capable of emitting light in the solid state. The electroluminescent device comprises a pair of electrodes and an electroluminescent layer disposed between the electrodes. The electroluminescent layer partly comprises a complex of a metal in group IV of the element periodic table because such a metal complex has a good film-formability and an excellent carrier transporting ability and emits light even in the solid state. Since the emission wavelength of the complex of a metal in group IV is longer than that of conventional host materials (Alq3), the electroluminescent layer can be formed of a combination of the metal complex and a guest material capable of emitting red light.
