MASK AND OPTICAL FILTER MANUFACTURING APPARATUS INCLUDING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a mask and an optical filter manufacturing apparatus for use in a roll-to-roll process, which can uniformly form a pattern on a base film, can improve the quality of a product, and can accurately realize characteristics of the base film.SOLUTION: The apparatus is formed from: a base film 50 wound around a roll; a light source 10 that generates light for exposure; a polarizing plate 30 that is installed at an emission side of the light source and polarizes light generated from the light source; and a mask 40 that causes a pattern to be formed on the base film and includes a plurality of guide slits that are opened to have a predetermined thickness and a predetermined width. The entire surface of the base film 50 is irradiated with a uniform light quantity.
