MASK AND OPTICAL FILTER MANUFACTURING APPARATUS INCLUDING SAME

摘要

The present invention relates to a mask and an optical filter manufacturing apparatus including same. An optical filter manufacturing apparatus of the present invention comprises: a roll used in a roll to roll process; a base film wound on the roll; a light source emitting light for exposure; a polarizing plate installed at the emitting side of the light source to polarize the light emitted from the light source; and a mask for forming a pattern on the base film, and including a plurality of open guide slits formed therein having a predetermined thickness and width. According to the optical filter manufacturing apparatus having the mask of the present invention, a pattern can be formed uniformly on a base film because light can be radiated evenly across the entire surface of the base film, thus providing improved product quality and accurate realization of the base film's properties.
