    Abstract: A dibenzoborole-based compound and an organic light-emitting device including the same. The dibenzoborole-based compound is represented by the formula A1-(A2)n1, wherein A1 may be selected from specific aromatic and non-aromatic carbocycles and heterocycles, n1 may be an integer selected from 1 to 10, and each A2 moiety may independently be selected from a group represented by Formula 2: The dibenzoborole-based compound may be included in the hole transport region or hole transport layer. When the dibenzoborole-based compound has strong electron acceptor characteristics, the hole injection barrier between the anode and the organic layer may be reduced, and thus, an organic light-emitting device including the dibenzoborole-based compound may have high efficiency and a long lifespan.

    Abstract: A deposition apparatus includes a chamber, a stage which is disposed within the chamber and on which a target substrate is seated, a deposition source disposed within the chamber and including a deposition material, a plurality of nozzles connected to the deposition source within the chamber to inject the deposition material in a direction of the stage, and an ionizer disposed between the nozzles and the stage to charge the deposition material injected from the nozzles. A first electric field is generated in each of the ionizer and the nozzles, and a second electric field having an intensity less than the first electric field is generated between the stage and the ionizer. Each of the nozzles includes a plurality of protrusion tips disposed on an inner surface of each of the nozzles to charge the deposition material.
