Abstract
A display device including a substrate, a first electrode formed over the substrate, and a partition member having a first aperture is provided. The display device further includes an emitting control layer covering a portion of the first aperture, thereby providing a second aperture to expose a portion of the first electrode, wherein the second aperture has a quadrangular shape with chamfered corners which help disperse organic material uniformly. Advantageously, the emitting control layer is formed of a material having an affinity to an organic material forming an organic light emitting layer within the second aperture, thereby helping to disperse the organic material uniformly and improve brightness uniformity.
