ORGANIC ELECTROLUMINESCENT DEVICES AND ORGANIC LUMINESCENT MEDIUM

摘要

An organic electroluminescent device comprising a pair of electrodes and an organic luminescent medium layer which is placed between the electrodes and contains (A) a specific arylamine and (B) at least one compound selected from among specific anthracene derivatives, spiro fluorene derivatives, fused-ring compounds, and metal complexes; and an organic luminescent medium containing the components (A) and (B). The organic electroluminescent device exhibits high color purity, excellent heat resistance and a long lifetime and emits blue to yellow light at high efficiency, and the organic luminescent medium is suitable for use in such devices.
