An optical filter that may include a transparent substrate, a photocatalytic film formed on the back surface of the transparent substrate, a metal pattern formed by selectively exposing the photocatalytic film to light and growing a metal crystal thereon by plating, and a near-infrared ray shielding and photoselective absorbing layer formed on the metal pattern. Since the optical filter may exhibit superior color reproduction and excellent shielding performance against electromagnetic waves, near-infrared rays and neon light, it may be applied to a variety of image display devices, e.g., PDPs.
