ABSTRACT:
A cathode plate including a substrate, a cathode structure, a gate structure and emission sources is provided. The cathode structure and the gate structure are disposed on the substrate. The emission sources are arranged regularly on the cathode structure. A field emission flat lamp including said cathode plate, an anode plate and a sealant is provided. The sealant is disposed between and seals the cathode plate and the anode plate. Since the volume of each emission source is small, the bubbles resided inside the emission sources can be reduced, such that the qualities of the field emission flat lamp and the cathode plate thereof can be improved.
