Abstract: An organic light-emitting display apparatus includes: a substrate; a 1-1st pixel electrode in a 1-1st pixel to emit light of a first wavelength range and a 1-2nd pixel electrode in a 1-2nd pixel to emit light of the first wavelength range. The 1-1st pixel and the 1-2nd pixel are over the substrate; a pixel-defining layer covering an edge of the 1-1st pixel electrode and an edge of the 1-2nd pixel electrode so as to define a 1-1st exposed upper surface and a 1-2nd exposed upper surface; a 1-1st emission layer over the 1-1st pixel electrode and to generate the light of the first wavelength range and a 1-2nd emission layer over the 1-2nd pixel electrode and to generate the light of the first wavelength range; and an opposite electrode over the 1-1st emission layer and the 1-2nd emission layer.

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.
