ABSTRACT:
A method for manufacturing a high-transmittance optical filter for image display devices, which may include the steps of coating a photocatalytic compound on a transparent substrate to form a photocatalytic film, selectively exposing the photocatalytic film to light and growing a metal crystal thereon by plating to form a metal pattern, and selectively etching and removing the photocatalytic compound remaining on the transparent substrate using a buffered oxide etchant (BOE). According to the method, a high-transmittance, high-resolution and low-resistivity optical filter can be manufactured in a simple manner at low costs.
