    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.

    Abstract: A light-emitting device and an electronic apparatus including the same are provided. The light-emitting device includes a first electrode, a second electrode facing the first electrode, an interlayer between the first electrode and the second electrode and including an emission layer, and a capping layer. The emission layer includes a first emitter, the first emitter emits first light having a first emission spectrum, the capping layer is in the path on which the first light travels, an emission peak wavelength of the first light is from about 520 nm to about 550 nm. The first emitter includes iridium, the capping layer includes an amine-containing compound, and the value of ratio of CIEy to reflective index (RCR value) of the first light extracted to the outside through the capping layer is 38 or less, and the RCR value is calculated according to


    CIEy/R(cap)×100.
