Patent ID: 8338222

Claim:
A method of fabricating an organic light emitting display, comprising steps of: forming first, second and third electrodes, respectively corresponding to R (red), G (green) and B (blue) pixels, on a substrate; depositing a hole injection layer over the substrate and the first, second and third electrodes; depositing a common hole transport layer over the hole injection layer; thermally transferring a first organic layer from a base substrate to the common hole transport layer disposed over the first electrode, the first organic layer including a first hole transport layer and a first emission layer corresponding to each R (red) pixel; thermally transferring a second organic layer from the base substrate to the common hole transport layer disposed over the second electrode, the second organic layer including a second hole transport layer and a second emission layer corresponding to each G (green) pixel; thermally transferring a third organic layer from the base substrate to the common hole transport layer disposed over the third electrode, the third organic layer including a third emission layer corresponding to each B (blue) pixel; forming a hole blocking layer over exposed portions of the common hole transport layer and over each of the first second and third organic layers; forming an electron transport layer over the hole blocking layer; and forming a common electrode on the electron transport layer.
