PROBLEM TO BE SOLVED: To provide an organic light-emitting element, having a light output of high light emission efficiency and high luminance. SOLUTION: The organic light-emitting element has a pair of electrodes and a layer, containing one or a plurality of organic compounds between the electrodes. At least one layer among layers, containing the organic compounds, comprises oligofluorene compounds in general formula. At least a light-emitting layer among layers the comprising the organic compounds comprises one type of oligofluorene compounds and a luminescent compound that emits at least either type of fluorescence or phosphorescence. The weight ratio (B/A) is 1/100 to 100/100 for the (B) luminescent compound that emits fluorescence or phosphorescence and (A) the oligofluorene compound. COPYRIGHT: (C)2008,JPO&INPIT |
