An optical member for blocking EMI(Electro-Magnetic Interference), an optical filter including the same, and a display apparatus including the same are provided to enhance EMI blocking performance and to reduce a surface resistance by forming a metal layer having a thickness less than 12.5nm. An optical member for blocking EMI includes a base substrate and a lamination member formed on one surface of the base substrate. The lamination member is formed with a plurality of repetitive unit layers(10,20,30,40) including metal layers(12,22,32,42) and high refractive layers(51,52,53,54,55). One of outermost metal layers of the lamination member is formed with the metal layer having the least thickness. The high refractive layer is formed of Nb2O5. The metal layer is formed of Ag. The repetitive unit layer further includes at least one metal oxide layer adjacent to the metal layer.
