A method of fabricating an organic light emitting display is capable of improving device characteristics by patterning a plurality of organic layers of an emission layer and a charge transport layer using a thermal transfer method to optimize thicknesses of the organic layers corresponding to R, G and B pixels. The method includes: forming lower electrodes of R, G and B pixels on a substrate; forming an organic layer on the layer; and forming an upper electrode on the organic layer. Formation of the organic layer includes forming a portion of a hole injection layer and a hole transport layer of the R, G and B pixels over an entire surface of the substrate, the organic layer comprising a first portion and a second portion, the organic layer having a thickness equal to a sum of the thicknesses of the hole injection layer and the hole transport layer. Formation of the organic layer further comprises patterning the second portion of the organic layer, and patterning emission layers of the R, G and B pixels. The second portion of the organic layer and the emission layers of the R, G and B pixels are simultaneously formed by a thermal transfer method using a thermal transfer device having the second portion of the organic layer and the emission layers of the R, G and B pixels as a transfer layer. |
