A method of fabricating an OLED is provided. The method includes providing a substrate, in which a pixel electrode is formed. In addition, the method includes laminating a donor substrate attached to a frame on an entire surface of the substrate, and irradiating a laser to a predetermined region of the donor substrate to form an organic layer pattern on the pixel electrode. The present invention provides a method of fabricating the OLED capable of suppressing generation of contaminants such as particles and so on, and preventing the donor substrate from sagging or bending, as well as improving transfer efficiency since the donor substrate and the substrate are readily adhered to each other to maintain vacuum state.

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:
A donor substrate for laser transfer comprises: a base film; a light-to-heat conversion layer formed on the base film; and a transfer layer formed of an organic material on the light-to-heat conversion layer. The transfer layer contains a thermosetting electroluminescent material, and an organic electroluminescence display device is manufactured using the same. Thus, R, G and B emission layers are simply formed with a fine pattern by a thermal curing process after laser transfer. As a result, the emission layers are not damaged, and the manufacturing cost of a full-color organic electroluminescence display device is reduced due to employment of a simplified mask process. The donor substrate is advantageous to use in the manufacture of a large-sized organic electroluminescence display device.

The invention is directed to an organic electroluminescent (EL) display device having an improved light extracting efficiency due to a photonic crystal layer formed proximate one side of a stack. Among other elements, the stack may include a first electrode formed on a substrate, an organic light emitting layer formed above the first electrode, and a second electrode formed above the organic light emitting layer. Additionally, the photonic crystal layer may be configured to correspond to a wavelength of colored light. An organic EL display device having an improved light extracting efficiency may be manufactured using a thermal transfer donor film to adhere the photonic crystal layer to the stack.
