Method for fabricating organic electroluminescent display
Relating to a method for fabricating an organic electroluminescent display having improved surface flatness and thickness uniformity as well as an improved image quality at edge regions of a pattern, a method for fabricating an organic electroluminescent display includes the steps of: forming a first electrode layer on a transparent substrate, the first electrode layer being a positive electrode; forming an assistant layer on the first electrode layer; forming an organic luminescent layer on the assistant layer by scanning a donor film using a laser beam, the donor film being disposed on the substrate having luminescent materials for R, G, and B; removing the donor film; and forming a second electrode layer on the organic luminescent layer, the second electrode layer being a negative electrode, wherein the step of forming an organic luminescent layer comprises the step of dithering the laser beam in a direction perpendicular to a scanning direction of the laser beam.
