A black matrix, a method for preparing the black matrix, a flat panel display and an electromagnetic interference filter using the black matrix. The black matrix may comprise a substrate, a titanium oxide layer, a Ni plating layer, and a Ni/Pd alloy layer. The method may comprise the steps of forming a titanium oxide layer, forming a metal particle-deposited pattern on the titanium oxide layer, forming a Ni electroless plating layer on the metal particle-deposited pattern, and forming a Ni/Pd alloy layer on the Ni electroless plating layer. Since the black matrix may have a high blackening density via simple selective multilayer plating without using a high-price vacuum sputtering apparatus and undergoing photolithography, unlike conventional chromium-based black matrices, it may be employed in various flat panel displays. In addition, since the black matrix may exhibit superior electrical conductivity, it may be used in electromagnetic interference filters without additional front-surface blackening.
