Abrégé
(EN)
The utility model discloses an organic light emitting element. Disclosed organic light emitting element includes: the first electrode, the organic emission layer in many sublayers on the first electrode, second electrode on the organic emission layer in many sublayers, and mixed barrier layer, it is in to mix the barrier layer the organic emission layer in many sublayers adjacent and including twosublayers of first solvent between each other to construct including have with the second solvent of the opposite pole nature of first solvent. Such organic light emitting element can have the luminous efficacy of improvement and the life -span of improvement.
