摘要： The present invention relates to a flat panel display, and more particularly, to a method of fabricating an organic light emitting display device so as to improve device characteristics by patterning a plurality of organic layers using a heat transfer method to optimize thicknesses according to R, G and B pixels. The method includes: forming lower electrodes of R, G and B pixels on an insulating substrate; forming an organic layer on the insulating substrate; and forming an upper electrode on the organic layer. Formation of the organic layer includes forming a hole injection layer and a hole transport layer of the R, G and B pixels on the entire surface of the substrate as a common layer. The R and G emission layers are patterned by a heat transfer method using a heat transfer device having a transfer layer such that an organic layer is patterned to a thickness obtained by subtracting a thickness of the B emission layer from the thicknesses of the R and G emission layers required in R and G colors.

摘要： An organic electroluminescence display device made by a laser induced thermal imaging process has a substrate having first and second electrode layers, and an organic layer having red, green, and blue light-emitting layers between the electrode layers. Thermosetting light-emitting materials are used to form the red, green, and blue light-emitting layers, and a laser is then selectively irradiated onto a light-to-heat conversion layer formed on the substrate to deliver heat energy converted from light energy through the light-to-heat conversion layer to the thermosetting light-emitting materials so that curing is progressed to form patterned light-emitting layers. In accordance with the fabrication method of the present invention, the light-emitting materials may be patterned using a laser, thereby fabricating a large scaled organic electroluminescence display device and simplifying the process by not using a mask when the light-emitting layers are formed.
