Method of manufacturing organic light-emitting display apparatus

A method of manufacturing an organic light-emitting display apparatus, the method comprising:

• preparing a substrate with a plurality of pixel electrodes;
• preparing a donor mask, such that the donor mask includes a base substrate, a light-thermal conversion layer on the base substrate, and a reflective layer between the base substrate and the light-thermal conversion layer and having through-holes;
• depositing a transfer layer on the light-thermal conversion layer of the donor mask;
• aligning the substrate and the donor mask;
• preheating at least a portion of the donor mask or the transfer layer;
• and
• irradiating a light source toward the preheated portion of the donor mask or the transfer layer, such that a portion of the transfer layer is transferred from the donor mask to the plurality of pixel electrodes of the substrate, the transferred portion of the transfer layer corresponding to the through-holes in the reflective layer,
• wherein:
• preheating includes irradiating a preliminary laser beam toward at least a portion of the donor mask, such that a corresponding portion of the transfer layer is preheated;
• and
• irradiating includes irradiating a laser beam different from the preliminary laser beam toward the preheated portions of the donor mask and the transfer layer.

• wherein:
• preheating includes irradiating a preliminary lamp light toward at least a portion of the donor mask, such that a corresponding portion of the transfer layer is preheated;
• and
• irradiating includes irradiating a lamp light different from the preliminary lamp light toward the preheated portions of the donor mask and the transfer layer,
• wherein an intensity of the preliminary lamp light is lower than an intensity of the lamp light.
