Abstract
Disclosed is a field emission display device which can prevent mixing of colors between the phosphor elements of the field emission display device. In the field emission display device, an upper substrate and a lower substrate are spaced apart with a predetermined gap and opposed to each other. Cathode assemblies are formed in a shape of stripes on the lower substrate. Anodes are formed on the upper substrate, and black matrices are formed on the anodes. The black matrices are disposed at locations respectively corresponding to every space between the cathode assemblies, so as to respectively have a shape of a partition. R, G, and B phosphor elements are formed in spaces between the black matrices, so as to respectively correspond to the cathode assemblies.
