A method for fabricating an electronic emission source of a field emission display includes to provide a substrate, screen print or lightgraphic etching the laminate to form a cathode electrode layer within the cavities, wherein the surface of the cathode electrode layer fabricates a photoresist by lightgraphy technology, coat a low viscosity carbon nano-tube solution to the surface and depositing it in the cavities, remove the photoresist by vacuum sintering and etching to form an electron emission sources layer having flat surface within the cavities. Comparing with the conventional arts, the present invention is to provide a better flatness, which improves the uniformity of images and brightness. In addition, the present invention enhances the density of Carbon Nano-Tube ("CNT") and thereby improves the electron density of the electron beams. The structure of the electron emission sources includes a cathode fabricated in a substrate; a cathode electrode layer with cavities formed in the surface of the cathode; and an electron emission sources layer produced by etching, sintering and depositing in the flat surface of the cavities.
