Abstract: A novel black matrix, a method for preparing the same, and a flat display device and an electromagnetic interference filter to which the black matrix is applied. The black matrix is prepared by exposing a photoactive compound to form a latent pattern of nuclei for crystal growth and treating the latent pattern of nuclei for crystal growth with a metal salt solution to give a metal particle-deposited pattern; forming an electroless Ni-plated layer on the metal particle-deposited pattern; and forming an electroless Cu-plated layer on the electroless Ni-plated layer. Exhibiting improved black tone, which is achieved only by a selective multilayer plating process, without using expensive vacuum sputtering apparatus or a photolithographic process, the black matrix can be applied to various flat display devices. In addition, due to improved electric conductivity, the black matrix can be used in an electromagnetic interference filter, without employing an additional front surface blackening process.

Abstract: 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.
