A manufacturing method for an organic light emitting display includes forming a first electrode on a target substrate and forming a bank layer including an aperture region that exposes the first electrode; bonding the target substrate and a medium substrate oppositely spaced apart from a top portion of the target substrate and having an organic material layer, an absorption layer, a reflective layer, and a donor substrate sequentially arranged thereon; transferring an organic material layer onto the first electrode exposed in the bank layer by irradiating a laser onto the medium substrate to form an organic light emitting layer; and separating the target substrate and the medium substrate from each other and forming a second electrode on the organic light emitting layer formed on the target substrate, wherein the reflectivity of the absorption layer is lower than the reflectivity of the reflective layer.
