Abstract:
1. A method of fabricating an organic light emitting display device, comprising the steps of: forming lower electrodes of R, G and B pixels on a substrate; forming an organic layer on the substrate; and forming an upper electrode on the organic layer; wherein the step of forming the organic layer comprises: forming hole injection layers and hole transport layers of the R, G and B pixels on an entire surface of the substrate as a common layer; forming R and G emission layers on the hole transport layers of the R and C pixels, respectively; and forming a B emission layer as a common layer on an entire surface of the substrate which includes the R and G emission layers; wherein the R and G emission layers are formed by patterning through a heat transfer method using a heat transfer device having a transfer layer so that the R and G emission layers are patterned to a thickness obtained by subtracting the thickness of the B emission common layer from optically optimized thicknesses of an R emission layer and a G emission layer required in R and G colors in a case where the B emission layer is patterned and not common.
