Abstract:
1. A method of fabricating an organic light emitting display, comprising: providing a substrate having a pixel electrode formed thereon; laminating a donor substrate on an entire surface of the substrate; and forming an organic layer pattern on the substrate by irradiating a predetermined region of the donor substrate with a homogenous laser beam using a laser irradiation apparatus, the laser irradiation apparatus having a spatial light modulator (SLM) to provide the homogenous laser beam, wherein the SLM adjusts various types of incident light, using a reflection surface having a deformed shape, to output the homogeneous laser beam, wherein the SLM comprises a plurality of diffraction lattices formed in a pillar shape, the reflection surface being arranged between the plurality of diffraction lattices, and wherein a voltage applied to the diffraction lattices deforms the reflection surface so that a depth of the reflection surface from a surface of an adjacent diffraction lattice changes.
