Abstract
An organic light emitting element is disclosed. The organic light emitting element includes: a first electrode; a multi-sub-layered organic emission layer on the first electrode; a second electrode on the multi-sub-layered organic emission layer; and a blend barrier layer between two sub-layers of the multi-sub-layered organic emission layer, which are adjacent to each other and includes first solvents, and configured to include a second solvent having an opposite polarity to that of the first solvent. Such an organic light emitting element can have enhanced light emission efficiency and extended life span.
