To provide an organic light-emitting element using a fluorene derivative which allows a blue luminescent material excellent in color purity to emit light.
The organic light-emitting element having one or a plurality of organic layers including a light emitting layer between a pair of electrodes is arranged such that at least one layer of the above-mentioned organic layers contains a compound as expressed by the following general formula (1) independently or as a mixture,
(A, B, C: hydrogen, substituted or unsubstituted phenylene group, naphthalene group, biphenylene group, fluorene group, or carbazole group. A and B may form a saturated ring bond. R 1 -R 5 : hydrogen, alkyl group, cycloalkyl group, alkoxy group, cycloalkoxy group. R 6 -R 13 : hydrogen, halogen, cycloalkyl group, alkoxy group, cycloalkoxy group, aryloxy group, substituted or unsubstituted phenylene group or biphenylene group. no, n 1 : 1 or 2. n 2 , n 3 : integer from 1 to 8. X: single bond which connects unit (a) and unit (b).) |
