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. | 12-18-2008 |
